Functonal Overvew Ths manual should be read n conjuncton wth the Detectve+ user manual. Detectve Net s a cable replacement wreless soluton for Detectve or Detectve+ allowng wreless transmsson of gas alarm events between devces. A gas alarm event on a Detectve+ shall cause an alert to be transmtted to all other Detectve Net devces on the network whch n turn wll cause all Detectve+ unts n the network to go nto alert. Ths wll ensure that all personnel beng protected by the network are alerted to a gas event that may be remote from ther current locaton. Detectve Net s smply connected to the exstng nterconnectng cable connector and s suppled wth a clp for mountng. A Detectve Net devce can be confgured as ether a master or a slave devce and a full wreless network can consst of one master devce master and up to 25 slave devces. The wreless network can be ether confgured pror to deployment or once the devces are deployed. It s also possble to add or remove further slave devces once a network s confgured and operatonal. 5

Glossary Ths secton detals the terms used wthn ths manual. Detectve Net Master Devce One devce n each network must be confgured to be a master devce that wll control the network and all slave devces. Detectve Net Slave Devce A network wll consst of one master devce that controls the network; all other devces wll be slave devces. Network Hoppng Network hoppng descrbes the process of the master Detectve Net devce communcatng not drectly wth a slave devce but by passng the message through another slave devce, or hoppng. Learn Mode All slave devces must be confgured to operate wth the master devce n the wreless network. Learn Mode descrbes the process of learnng a slave devce to the master devce. Slave devces must be learned to the network pror to deployment. Gas alarm A gas alarm s ntated when a Detectve+ unt detects gas and goes nto alarm wth the beacon and lghts n operaton. Network Alert A network alert s the response of the network to a gas alarm event on a Detectve+ unt wthn the network. A network alert wll cause all other Detectve+ unts wthn the network to go nto network alert mode, beacon and lghts wll flash at a slower rate than a gas alarm to dfferentate t. Force Communcaton If no wreless connecton exsts between devces, the force communcaton feature can be utlzed to re-establsh communcatons by pressng any button on a slave devce. 10
Modulated Alert A Modulated Alert s a response of Detectve Net to a problem wth the Detectve Net devce, for example f a slave Detectve Net devce has lost connecton to the network a modulated alert wll be sent to the locally-attached Detectve+. The wll cause Detectve+ to go nto Modulated Alert, the beacon and lghts wll flash for 3 seconds followed by a 5 second pause; ths pattern wll then be repeated. Network Connecton Test Once a network has been confgured, deployed and connected to Detectve+ unts t s possble to undertake a network connecton test to ensure all Detectve Net unts are confgured correctly and are wthn range on the network. A Network Connecton Test wll cause all devces confgured wthn the network to be placed n Network Alert for 10 seconds. RICOCHET Mesh Network Each Detectve Net devce can provde alternatve wreless transmsson routes. Should a wreless connecton between two Detectve Net devces weaken, the network automatcally re-routes communcaton va alternatve Detectve Net devce. Ths creates a mesh type network allowng a more robust and effcent wreless network. 11

Contents 1.5 Functon buttons Detectve Net has two buttons (FB1 À and FB2 Á) that control the functonalty of the devce. Fgure 5: Functon buttons À Overvew Á Glossary Operaton Specfcaton Servce and mantenance Troubleshootng Accessores Button functonalty s as follows: 1.5.1 Functon Button 1 (FB1) Hold down for 3 seconds (Devce off) Double clck Warranty Contacts Hold down for 3 seconds (Devce on) Powers up devce Unlearns a slave devce from a confgured network (master devce wll also need to be n learn mode to perform ths operaton) Resets a master or a slave devce 1.5.2 Functon Button 2 (FB2) Hold down for 3 seconds (Devce on) Double clck Toggles functonalty between a master and slave devce, hold to change a master devce to a slave devce or vsa Enter/leave learn mode (slave devce wll leave learn mode automatcally) 1.5.3 Functon Button 1 (FB1) & Functon Button 2 (FB2) Ext Hold down for less than 1 second Intates a system network connecton test Hold down for 3 seconds (Devce on) Powers down devce 16
1.6 System Confguraton A Detectve Net wreless network can be confgured ether before deployment of Detectve+ unts n an offce or laboratory envronment, or durng deployment of Detectve+ unts n the feld. The followng sectons detal how to setup and confgure a wreless network. Ths process need only be undertaken once, f a network of confgured and learned wreless devces s powered down, upon beng powered up agan the devces wll retan the prevous confguraton and be able to operate mmedately. 1.6.1 Swtchng on a devce Hold down FB1 for 3 seconds. The LED ndcators wll llumnate sequentally left to rght to ndcate power up. LED1, LED2 or LED4 may be llumnated dependant upon prevous confguratons these can be gnored at ths stage; the devce must now be reset. 1.6.2 Resettng a devce A reset wll cause the devce to erase any prevous network confguraton but wll not change the functon of the devce. For example f the devce was prevously a master devce t wll contnue to be so after a reset but the master wll no longer retan any slave nformaton prevously learned. It wll effectvely become a blank master devce. Wth the devce powered up, hold down FB1 for 3 seconds. If the devce was prevously confgured a slave devce, LED1 wll flash 3 tmes to ndcate a successful reset on a slave devce. LED1 wll then contnue to flash red ndcatng the devce s a slave devce. X X If the devce was prevously confgured as a master devce, LED1 wll flash green and LED4 wll flash red 3 tmes to ndcate a successful reset on a master devce. LED1 wll then contnue to flash red and LED4 wll contnue to flash green ndcatng the devce s confgured as a master devce. 17
1.6.3 Toggle Devces between Master & Slave Functonalty Each network requres only one master devce; all other devces should be slave devces. One unt n the network should be confgured as a master devce and all other unts should be confgured as slave devces. To toggle between master and slave functonalty press FB2 for 3 seconds. If the devce was a slave devce and s beng toggled to a master devce LED4 wll flash 3 tmes ndcatng a successful toggle from a slave to a master. LED1 wll then contnue to flash red and LED4 wll contnue to flash green ndcatng the devce s confgured as a master devce. If the devce was a master devce and s beng toggled from a master to a slave devce LED1 wll flash 3 tmes ndcatng a successful toggle from a master to slave. LED1 wll then contnue to flash red ndcatng the devce s confgured as a slave devce. 1.6.4 Settng Up a Smple Wreless Network Take a devce confgured as the master devce ensurng t has been reset (see Secton 1.6.2) and double-clck FB2 to enter learn mode. LED1 wll contnuously flash red, to ndcate devce s n the learn mode and LED4 wll contnue to flash green. Take a devce confgured as a slave devce ensurng t has been reset (see Secton 1.6.2) and place a mnmum of 1m apart from the master devce. The slave and master devces must be placed a mnmum of 1m apart to ensure correct operaton durng normal operaton and also when settng up the pared network. Double-clck FB2 on the slave devce to enter learn mode LED1 wll contnuously flash red to ndcate the devce s n learn mode. The slave devce wll learn automatcally and when complete, LED1 turns off and LED2 wll flash green to ndcate the slave s connected to the master. If the learn process s unsuccessful, the slave devce wll ndcate ths as LED2 wll flash red 3 tmes to show an unsuccessful learn and LED1 wll revert to flashng red to show powered up. The slave wll ext learn mode. If the devce had prevously been connected to a network, LED2 would revert back to ts prevous state and LED1 would reman off. X X The master devce wll ndcate a successful learn of a slave devce by a trple green flash on LED2 (ths wll only occur once) and LED1 remans contnuously flashng red, ndcatng the devce s stll n the learn mode. LED4 contnues to flash green ndcatng ts master status. 18
The slave devce s now confgured to the network. If requred, further slaves devces can be learnt to the network n the same manner as descrbed prevously. If no further slaves are to be added to the network double-clck FB2 button on the master devce to ext learn mode, LED4 contnues to flash green, LED2 wll flash green to show the slave s connected to the network and LED1 turns off. A network of one master and one slave devce has now been confgured for use. 1.6.5 Network connecton test Once a network has been confgured, deployed and connected to Detectve+ unts t s possble to undertake a network connecton test to ensure all Detectve Net devces are confgured correctly and are wthn range on the network. Press and hold both FB1 and FB2 on ether a master or slave devce momentarly to ntate a system connecton test. A network connecton test wll cause all devces confgured wthn the network to be placed n network alert for 10 seconds. If a confgured devce s not placed nto network alert upon ntaton of the network test, t may be out of range and must be moved closer to an adjacent devce. If a confgured devce cannot be moved closer to an adjacent devce, utlsng the 10m or 20m cable accessory t can be detached from the Detectve + mountng and elevated to mprove wreless connectvty. It s mportant to undertake a network connecton test once the network s setup and deployed. Ths ensures all devces are functonng and correctly connected to the network. 19
1.6.6 Addng addtonal slave devces to the network Once a network has been confgured further slaves can be added to the network at any tme: On the master devce, double-clck FB2 to enter learn mode. Take a devce confgured as a slave devce ensurng t has been reset (see Secton 1.6.2 on page 17) swtch on and place a mnmum of 1m apart from the master devce, then double-clck FB2 to enter learn mode, LED1 wll contnuously flash red to ndcate the devce s n learn mode. The slave wll learn automatcally and when complete, LED1 turns off and LED2 changes to a sngle green flash (network OK). The master devce wll ndcate a successful learn of a slave devce by a trple green flash on LED2 (ths wll only occur once) and LED1 remans contnuously flashng red, ndcatng the devce s stll n the learn mode. LED4 contnues to flash green ndcatng ts master status. The slave s now confgured to the network. To add further slave devces repeat the above process untl all requred slaves are confgured to the network. If no further slaves are to be added to the network double-clck FB2 button on the master devce to ext learn mode, LED4 contnues to flash green, LED2 wll sngle flash green to show the slave s connected to the network and LED1 turns off. It s mportant to undertake a network connecton test f slaves are added to the network. Ths ensures all devces are functonng and correctly connected to the network. 1.6.7 Removng Slave Devces from the Network Once a network has been confgured f a slave devce s to be removed from the network as t s no longer requred, ths must be unlearned from the network to prevent the network ndcatng a fault. If a slave devce s removed from a network to whch t was prevously learned, the master wll ndcate a fault by llumnatng LED2.To prevent ths, a slave must be unlearned from the network. Take the devce confgured as the master devce and double-clck FB2 to enter learn mode. LED1 wll contnuously flash red, to ndcate devce s n the learn mode and LED4 wll contnue to flash green ndcatng master status. X X Take the slave devce to be removed from the network and double-clck FB1 to enter unlearn mode, LED1 wll flash red contnuously, to ndcate t s n unlearn mode. 20
The slave wll unlearn automatcally and leave the network, f the slave successfully leaves the network LED2 wll flash green 3 tmes to ndcate successful unlearn then wll be extngushed to show devce no longer on the network. LED1 flashes red to show devce s powered. If the unlearn process s unsuccessful, the slave devce wll ndcate ths as LED2 wll flash red 3 tmes to show an unsuccessful unlearn then LED2 wll revert would revert back to ts prevous state pror to the unlearn process. The slave wll ext unlearn mode and be mantaned n the network. The master devce wll ndcate successful unlearn of a slave devce by a trple green flash on LED2 (ths wll only occur once) and LED1 remans contnuously flashng red, ndcatng the devce s stll n the learn mode. LED4 contnues to flash green ndcatng ts master status. Double-clck FB2 on master devce to ext Learn mode. LED4 contnues to flash green, LED2 wll flash green to show the slave s connected to the network and LED1 turns off. It s mportant to ensure the master devce exts learn mode or the network wll not operate correctly. The slave s now removed from the network. 1.6.8 Power Down master or slave devce When the wreless network s decommssoned to preserve battery lfe the master and slave devces should be powered down. Hold down both FB1 & FB2 for 3 seconds to power down. LED s wll flash rght to left to ndcate a power down sequence. 1.6.9 Powerng Up a Prevously confgured network If a network of confgured and learned wreless devces are powered down, upon the devces beng powered up agan the devces wll remember the prevous confguraton,.e. f they were prevously confgured as a master or slave. It s not necessary to reconfgure the network. The deployment nstructons on page 22 should then be followed. 21
1.7 Network Deployment Correct deployment of the wreless network s mportant as t wll ensure the system operates effectvely and relably. The followng nstructons assume that the network has prevously been confgured and all requred slave devces have been learned to a master devce pror to deployment (see Secton 1.7.1 below). However the network confguraton and master slave learn process could be undertaken durng the deployment process. The followng nstructons should always be followed when deployng the network: 1.7.1 Deployment Process All devces should be powered down and connected to Detectve+ wth the requred nterconnectng cable (see page 13). Before deployment ensure no Detectve Net devces are ndcatng a low battery. Any devce wth the battery ndcaton LED llumnated should not be deployed and should be unlearned from the network and replaced. Pror to powerng the detectve net devce ensure the Detectve + s powered and operatng normally, or the wreless devce wll deem the Detectve + to have exhausted ts battery and wll ntate an alert on the network. The master devce should be powered frst and placed as centrally as possble n the network (ths wll make best use of the benefts of the mesh network). LED2 wll flash amber twce to ndcate no network connecton (as no slave devces are powered at ths pont) and LED4 wll flash green ndcatng ts master status. When placng the slave devces start wth the devce closest to the master and work outwards. Place the frst slave devce n poston and power up, LED2 wll double flash amber to ndcate the slave devce has no wreless communcaton to the master devce and t s attemptng to establsh connecton. The slave devce may establsh communcaton quckly and LED2 wll then flash green 3 tmes, ndcatng communcaton to the master has been establshed. LED2 wll then revert back to a green flash ndcatng establshed network connecton. If the devce does not connect then use the force communcaton process to establsh connecton (see page 23). 22
If network connecton s stll not establshed t may be that the devces have exceeded the connectvty range wthn that gven envronment. Reposton the slave devce deally closer to the master devce. or closer to a slave devce that has successful communcaton and repeat the force communcaton process. Repeat ths process untl communcaton s establshed. If a confgured devce cannot be moved closer to an adjacent devce, utlsng the 10m or 20m cable accessory t can be removed from Detectve + and elevated to mprove wreless connectvty. Ths process should then be repeated for all confgured slave devces workng outwards from the master devce untl the full network has establshed communcatons. At ths pont all devces n the network should ndcate a fully functonng network by flashng LED2 green. Once all Detectve Net devces have been deployed a Network Connecton test must be performed. Ths ensures all devces are functonng and correctly connected to the network. Once all Detectve Net devces have been deployed a Network Connecton test must be performed. Ths ensures all devces are functonng and correctly connected to the network. If the sequence as descrbed above s not followed when powerng up the network, dependant upon the network confguraton t may take up to an hour before the whole network s fully establshed. 1.7.2 Force Communcaton The force communcaton process can be used to force a slave devce to re-establsh communcaton to a master devce. Press any button on the slave devce and ths wll force the slave to establsh communcatons wth the master devce. LED2 wll flash amber contnuously whlst the devce attempts to re-establsh communcatons, once communcatons s re-establshed LED2 should then sngle flash green. Once communcaton to the master has been re-establshed t s mportant to repeat the network connecton test and ensure all devces respond approprately. If the force communcatons process s unsuccessful and connecton s not re-establshed, LED2 wll flash red 3 tmes to ndcate unsuccessful communcatons and then LED2 wll contnue to double flash amber ndcatng the devce s tryng to re-establsh network connecton. The force communcaton process can be repeated several tmes. If the devce s unable to re-establsh network connecton LED2 wll double flash red ndcatng network connecton s lost. 23
Contents If t s not possble to establsh network t may be that the devces have exceeded the connectvty range wthn that gven envronment. Reposton the slave devce deally closer to the master devce, or closer to a slave devce that has successful communcaton and repeat the force communcaton process. Repeat ths process untl communcaton s establshed. If a confgured devce cannot be moved closer to an adjacent devce, utlsng the 10m or 20m cable accessory t can be removed from Detectve + and elevated to mprove wreless connectvty. 1.7.3 Network Topology Detectve Net can be deployed n varous standard topologes e.g. a rng or star network. Overvew Fgure 6: Network topology Glossary SLAVE SLAVE SLAVE MASTER Operaton SLAVE Specfcaton SLAVE Servce and mantenance SLAVE SLAVE Troubleshootng Accessores Warranty Contacts Ext To ensure a robust and relable network and also to maxmze the benefts of the mesh network the followng best practces should be followed: A network must contan only one master devce. A devce must not be deployed f the low battery LED s llumnated. Place the master devce as close as possble to the centre of the network. Wherever possble place slave devces such that wreless communcaton to the master s drect and network hoppng s not necessary. Place slave devces as close as practcally possble to other slave devces as ths wll ncrease the robustness of the mesh network allowng sgnals to be transmtted back to the master devce va several possble slave devces. Although Detectve Net devces have an auto power down feature, manually powerng down at the end of a deployment wll ncrease devce battery lfe. 24
Contents Overvew Glossary Operaton 1.7.3.1 Operatonal Consderatons Maxmum range s typcally up to 70m meters but ths may vary dependent upon the operatng envronment and other envronmental condtons. Ths can be extended by use of the 10m or 20m nterconnectng cable to obtan greater dstance between Detectve+ unts. Network hoppng descrbes the process of the master Detectve Net devce communcatng not drectly wth a slave devce but by passng the message through another slave devce, or hoppng. Ths may occur f the slave devce s placed at the maxmum dstance from the master devce. If each slave devces s placed at the maxmum dstance apart n a straght lne from the master devce network hoppng wll be utlsed. In ths case the maxmum number of hops n each drecton from a centrally located master devce wll be three, see Fgure 7.

1.8 Alarms and Alerts The followng secton detals the use cases when an alarm or alert wll be nstgated on the wreless network. 1.8.1 Gas alarm A Gas Alarm s ntated when a Detectve+ unt detects gas and goes nto alarm, Detectve+ beacon and lghts wll then be n operaton. A Gas Alarm wll cause the locally attached Detectve Net devce to transmt an alert to all other wreless devces on the network causng all other Detectve+ unts to ntate a Network Alert (see Secton 1.8.2). The locally attached Detectve Net devce wll ndcate a gas alarm event by a sngle flash on LED3. 1.8.2 Network Alert A Network Alert s a response of a specfc Detectve+ to the fact that another Detectve+ unt n the network s n Gas Alarm (or that a Detectve + on the network has turned off due to an exhausted battery). A Network Alert receved by a Detectve Net devce va the wreless network shall actvate a Network Alert on the locally attached Detectve+. Ths wll cause the Detectve+ to go nto Network Alert, the beacon and lghts wll flash at a slower rate than a Gas Alarm to dfferentate t from the Detectve+ that s n Gas Alarm. Dependant upon the deployment confguraton a Network Alert may take a number of seconds to be ntated on all Detectve+ unts as the alert message propagates throughout the network. The locally attached Detectve Net devce wll ndcate a Network Alert by a double flash on LED3. 27
1.8.3 Modulated Alert A Modulated Alert s a response of Detectve Net to a local problem wth the Detectve Net devce. It s not a response to a command va the wreless network. For example f a slave Detectve Net devce has lost connecton to the network a modulated alert wll be sent to the locally-attached Detectve+. Ths wll cause the Detectve+ to go nto Modulated Alert, the beacon and lghts wll flash for 3 seconds followed by a 5 second pause; ths pattern wll then be repeated. Ths modulated alert s to sgnfy a dfference to the Gas Alarm or Network Alert. The followng condtons can cause a Modulated Alert to be nstgated: A slave devce losng network connecton to a master devce (see Secton 1.9.2) A Detectve Net devce detects a low nternal battery (see Secton 1.9.4) A Detectve Net devce detectng an nternal fault (see Secton 1.9.6) A Detectve Net devce n Modulated Alert sgnfes a fault wth ether the network or the Detectve Net devce and should be nvestgated and rectfed mmedately to ensure the wreless network contnues to functon as desred. 28
1.9 Network Operaton The followng secton detals operaton of the wreless network ncludng scenaros that may be encountered durng normal operaton. 1.9.1 Normal Operaton In normal operaton the wreless network should operate unobtrusvely. If the network s functonng correctly all slave devces and the master devce wll be flashng LED2 green (the master devce wll contnue to flash LED4 green ndcatng ts master status). A gas event on a Detectve+ wll cause that unt to go nto Gas Alarm (see Secton 1.8.1) and the locally attached Detectve Net devce wll ntate a Network Alert (see Secton 1.8.2). Ths wll cause all Detectve+ unts on the wreless network to go nto Network Alert. 1.9.2 Loss of Connecton to Wreless Network If Detectve Net devce loses connecton to the wreless network, for example f an obstructon s placed between devces after deployment, t wll ndcate ths to the user. If a slave Detectve Net devce has lost connecton to the master devce, t wll double flash LED2 amber to ndcate that connecton has been lost and that t s attemptng to re-establsh connecton. Detectve Net wll attempt to re-establsh connecton at regular ntervals. The master Detectve Net devce wll ndcate a slave devce has lost connecton and s attemptng to re-establsh connecton by a double amber flash on LED2. It must be noted that due to the mechansm of the wreless network t may take several mnutes for LED2 on the master to be llumnated amber. If a slave devce cannot re-establsh wreless connecton to the master, LED2 wll flash red to ndcate that network connecton has been lost and ths wll ntate a Modulated Alert (see Secton 1.8.3) on the locally attached Detectve+ unt. The master Detectve Net devce wll ndcate a slave devce has lost connecton and s attemptng to re-establsh connecton by a double amber flash on LED2. It must be noted that due to the mechansm of the wreless network t may take several mnutes for LED2 on the master to be llumnated amber. Detectve Net wll contnue to attempt to re-establsh connecton but at reduced ntervals and after approxmately 13hrs t wll cease tryng to re-establsh connecton and power down. Detectve+ wll reman powered untl ts on battery becomes depleted. Detectve Net wll contnue to keep the locally attached Detectve+ n Modulated Alert throughout the 13hr perod (f Detectve+ has suffcent battery lfe). 29
If the master Detectve Net devce s the cause of the slave devce loosng connecton to the network,.e. t has been nadvertently damaged or swtched off, then all slaves devces wll perform as descrbed above and eventually all slave devces wll ntate a Modulated Alert on the locally attached Detectve+ unt. It must be noted that due to the mechansm of the wreless network slave devces wll not ntate Modulated Alert smultaneously; t may take several mnutes before all unts are n modulated alert. If the master wreless devce s lost from the network due to damage or exhausted battery the network wll n essence no longer functon as slave cannot automatcally become the master. 1.9.3 Re-establshng Network Connecton If network connecton has been lost between a slave Detectve Net devce and the master Detectve Net devce and the reason for the loss of communcaton has been resolved and LED2 s double flashng amber ndcatng network communcaton has not be re-establshed, mplement the Force Communcatons feature (see Secton 1.7.2) to quckly re-establsh communcatons. Ths process must be repeated for each slave devce that has lost network connecton and LED2 s double flashng amber. If ths process s not followed, dependant upon the network confguraton t may take up to an hour before the whole network re-establshed. If the Master Detectve Net devce had nadvertently been powered down, causng the network to be lost but has now been repowered. It s recommended to power down all wreless devces and follow the normal power up sequence (see Secton 1.7.1). Ths wll ensure the network s re-establshed n the quckest and most effcent manner. If ths process s not followed, dependant upon the network confguraton t may take up to an hour before the whole network re-establshed. It s then mportant to undertake a network connecton test to ensure all devces have been correctly establshed on the network. 30
1.9.4 Detectve Net Devce - Low Battery Alert Detectve Net montors ts battery status and f the battery s at the end of ts lfe the battery ndcaton LED wll be llumnated and ths wll ntate a Modulated Alert (see Secton 1.8.3) on the locally attached Detectve+ unt. A Detectve Net devce that llumnates ts battery low LED upon start up should not be deployed n a wreless network. The devce should be returned to your local Crowcon offce or agent for battery replacement. 1.9.5 Detectve+ - Power Down or Inadvertent Swtch Off If Detectve+ powers down due to the battery beng depleted or due to beng physcally turned off, the locally attached Detectve Net wll ntate a Network Alert (see Secton 1.8.2) on the rest of the network. Ths wll cause all Detectve+ unts on the wreless network to go nto Network Alert wth beacon and lghts ndcaton. If a powered Detectve Net devce s connected to an un-powered Detectve+, the Detectve Net wll nstgate an a Network Alert on the rest of the network as t wll see assume the Detectve+ unt that has an exhausted battery. If a Detectve+ goes nto low battery alarm, there wll be no ndcaton of ths on the wreless network. 1.9.6 Internal Fault Detectve Net nternally montors t s status and f an nternal fault s detected t wll ndcate ths by llumnatng the LED s n turn from rght to left and then mmedately left to rght. It wll then pause for 5 seconds and repeat ths cycle. It wll also ntate a Modulated Alert (see Secton 1.8.3) on the locally attached Detectve+ unt. The devce should be removed from the network and replaced wth a new slave devce. The new slave devce wll need to be confgured to the network (see Secton 1.6.4). It should be noted that a slave devce n fault mode that s physcally removed from the network wll not be unlearned from the master devce. The master wll contnue to show a mssng slave devce untl the unts are decommssoned; at ths pont the network should be reset and reconfgured to ensure the master devce does not nclude the removed slave devce n ts network. A devce that s ndcatng an nternal fault wll not operate correctly wthn the wreless network, should not be used and should be returned to your local Crowcon offce or agent for repar/replacement. 31

4. Troubleshootng Table 2 Symptom Cause Acton A slave devce wll not learn to a master devce. Slave and master devces not a mnmum of 1m apart. Place master and slave devce a mnmum of 1m apart and repeat learn process. Master devce not n learn mode. Check the master devce s n learn mode ndcated by a contnuous flash on LED1. A slave devce cannot be removed from the network, unlearn process from master devce not successful. Slave devce not n learn mode. Slave unt chosen s confgured as a master devce. Slave and master devces not a mnmum of 1m apart. Master devce not n learn mode. Check the slave devce s n learn mode ndcated by a contnuous flash on LED1. Toggle functonalty of devce to a slave devce. Place master and slave devce a mnmum of 1m apart and repeat learn process. Check the master devce s n learn mode ndcated by a contnuous flash on LED1. Slave devce not n unlearn mode. Check the slave devce s n unlearn mode ndcated by a contnuous flash on LED1. 34
Symptom Cause Acton Network communcaton can not be establshed at deployment ndcated by amber or red LED 2 or by a slave devce not respondng to a network connecton test. Detectve Net LED s llumnatng n turn from rght to left then left to rght repeatedly. Devces placed too far apart or envronmental condtons are challengng for the network. Slave devce may not be learned to master devce. Interconnectng cable may be damaged. Detectve Net devce has detected an nternal fault. Devces should be postoned closer together then force communcatons and network connecton test processes ntated. Use extended 10m or 20m nterconnectng cables to elevate Detectve Net to mprove network connectvty. Deploy Detectve Net devces as repeaters to mprove network robustness n challengng envronments. Relearn slave to master devce. Replace nterconnectng cable and repeat network connecton test. Detectve Net devce must be removed from the network and replaced wth a new unt. 35

6. RICOCHET Mesh Technology RICOCHET mesh technology s rapdly becomng the recognzed standard for wreless systems n the securty, lfe safety, ndustral and buldng automaton ndustres. RICOCHET mesh technology was created for three reasons: To create a wreless mesh network technology for contnually supervsed battery operated devces. To reduce the complexty of wreless product desgn, protocol development, equpment nstallaton and usage. To enable the development of wreless systems that can go further, be smarter and be easer than ever before. RICOCHET enabled wreless devces receve and repeat wreless transmssons from other devces. The sze, scalablty and range of an entre system are extended, as wreless sgnallng s no longer lmted by pont-to-pont communcatons. Each RICOCHET enabled devce provdes alternatve wreless transmsson routes. Should a wreless connecton between two devces weaken, the network automatcally re-routes communcaton va alternatve RICOCHET enabled devces. RICOCHET easer, smarter, further. 37
