4 GENERAL INFORMATION The following general procedures must be observed in relation to the location and installation of System One Home Communication components: Stations are not to be installed back to back or in line of sight of each other as this will cause feed-back (squealing). Where stations are to be fitted externally, appropriate measures to provide protection from weather are to be taken. Avoid running Intercom cable in parallel to electrical wiring. The Power supply is not to be installed in a cavity wall or any area (roof etc) where temperatures are likely exceed 86º F. Guidelines for maximum cable lengths as set out in this manual are to be observed to avoid the possibility of operating problems due to excessive voltage drop. The maximum number of stations on a system including Master, Room and Door stations is generally limited to 20. It is important that the power supply is properly matched to the size of the system. (See Power Supply Page 25) CAUTION: Failure to use Valet cable may cause problems with the performance of the system and will void warranty on the equipment. IMPORTANT: Responsibility will not be taken for problems that arise from the improper use of cable or interference generated externally to the system. Interference by light dimmers, fluorescent lighting and similar electrical products, must be corrected at the source. An aid to reducing the effects of this type of interference is to place stations and wiring no closer than (12 ) from any AC device or wiring. The circuitry of the intercom has been designed to minimize the effects of Radio Frequency Interference however total immunity to this type of interference cannot be guaranteed where the levels of interference generated are extreme. 2

5 LOCATION OF EQUIPMENT Master Station (Optional, Special Order Only) Where a master has been purchased as part of the system, it is generally located above the breakfast bar in the kitchen/family room at a suggested height of 55 from the floor to the center of the unit. As all wiring from other stations is generally terminated at the rear of the master, the walls should be no less than 2 ¾ in depth. A timber wall box should be inserted so as to allow for correct support of the master station. IMPORTANT The master station should be installed in a cavity wall and not a single brick wall in order to facilitate the wiring behind it. Where there is wall tiling around or near to the master station, ensure the master station is mounted either completely within or completely clear of the tiled area as failure to do so will result in the master being affixed to an uneven surface. 3

6 Room Stations Careful consideration must be given to present and/or future layout of furniture so as not to locate stations in inappropriate positions. To avoid audio feedback, room stations should be kept at least 12 to 16 feet away from other stations. Never have more than one station in any one room and avoid mounting stations in the same wall cavity i.e. directly below and above one another in a two storey house. A suitable height is generally 55 from the floor to the center of the unit. Stations located on timber frame walls should be located adjacent stud to allow for firm fixing. to a Stations located on cavity brick walls will require the installation of wall boxes. Stations installed on single brick walls will also require wall boxes however the cable will need to be chased and conduited into the brick wall. The rear of the brick wall will need to be rendered or lined as the depth of a room station is approximately the same as a brick. Where stations are required in bathrooms or laundries, they must be kept clear of water or steam. Where stations are mounted on a tiled surface, a wall box should be installed prior to lining/tiling of the walls and the tiles will need to be cut to the inside dimensions of the wall box. Where room stations are mounted outside and are exposed to the weather, the fitting of weather proof covers will be required. Stations must not be installed in saunas. 4

7 Front Door/Gate Station(s) These stations are best located adjacent to the front door or at the front gate at a suggested height of 55 and may require a wall box depending upon the surface to which they are to be affixed. Any Station exposed to the weather will require the fitting of a weatherproof cover. Where stations are to be installed in solid brick or concrete columns at a front gate, it is required that the cable be run in conduit from the station to ground level and back to the house. Power Supply The power supply is usually located no less than 6 feet and not more than 16 feet from the point of connection at the System One Room Station. Suggested locations are kitchen cupboards, pantry, bedroom wardrobes etc. Because the power supply dissipates heat more effectively in a cool environment it is recommended that the supply not be located in the roof space of a dwelling. It is also advantageous to have easy access to the supply should it be required that the system be turned off. Antenna (AM/FM Aerials) The antenna arrangement is a critical part of the installation if a quality radio reception is required. The AM and FM aerials should be located in the highest point of the roof and at least 6 feet away from any electrical or intercom wiring. Because the FM antenna is directional, experimentation with positioning is recommended to achieve the best possible result. Where the roof is lined with foil insulation or is of metal construction, an external whip or car radio antenna may be required for AM. Connecting a specialized FM antenna or connecting to a TV antenna can greatly improve FM reception in poor signal areas. 5

8 Auxiliary Input Jack Optional accessory allowing music from an external source such as a Tape Deck, CD player or walkman to play throughout the Intercom System. Two different types of Input Jack are used: - Type A - For use with a Master Type B - for use without a Master The Input Jack should be installed in a wall near the location where the external music source is to be situated. NOTE: An appropriate lead will be required to connect the music source to the Input Jack. The use of appropriate cable from the Input Jack to the master (or from the Input Jack to a room station where a master is not used) is essential. See section What Cable To Use. Auxiliary/Lock Output Board Optional Accessory allowing Electronic door locks, Automatic gates, Courtesy lights, Alarm panic circuits, etc. to be controlled from the Master or any Room station. There are two (2) outputs on each board which can individually be programmed to time out or toggle depending on the application. Four (4) of these boards can be fitted to any one system allowing a total of eight (8) Auxiliary outputs in total. Each board is fitted in conjunction with a room station and is located in the side compartment of the room station back housing. NOTE: Additional wiring is required for this feature to be available. See section What Cable To Use. 6

9 WHERE TO RUN CABLE Cables can be run either: In the roof space In false ceilings/bulkhead area Through and/or around external walls Under floors (subject to access being available) Note: Intercom cables should be run as far away from AC wiring as practicality permits. Avoid running intercom cable in parallel to AC or any other type of wiring. (Running across at right angles is OK where necessary) All aerial wires should be taken to the highest and most accessible point in the roof. Allow additional cable at each station for the purpose of termination. (At least 3 feet ) In the case of cavity brick walls, ensure the wires are pulled through one of the holes at the rear of the wall box. 7

10 WHAT CABLE TO USE? General System One is designed to operate using 8 core cable however operation is also possible using 6 core cable with the disadvantage that music will be muted at all room stations while private communication is in progress. The system may be Star Wired from a central point or Loop Wired however the number of stations on a loop is governed by the length of the loop, and also whether or not a standby battery is being used in conjunction with the supply. See section Maximum Cable Lengths. Important Note: Different cables have different characteristics hence it is recommended that Valet Cable be used on all new installations. Many other cables will work acceptably HOWEVER RESPONSIBILITY CANNOT BE TAKEN FOR PROBLEMS THAT ARISE FROM THE USE OF OTHER CABLES. The proper use of shielded cable on VLC & TC terminals will prevent clicks & pops caused by Control Voltage changes from being induced onto audio lines. Power Supply Heavy duty Figure 8 cable (18 gauge or better) should be run from the Power Supply to the System One Room Station. AM Aerial The coaxial cable supplied with the master is to be run from the master to the highest point in the roof where the antenna tail provided (or a car radio antenna) must be plugged into the socket at the end of the cable. The plug at the master end of the cable must be cut off. Additional AM coax leads can be plugged into one another if additional length is required. FM Aerial Run the 300 ohm FM Ribbon antenna supplied with the master from the master to the highest point in the roof. If using coaxial cable to connect to an alternative 75 ohm antenna, be sure to fit a balun to the 300 ohm terminals at the master. 8

11 Auxiliary Input Jack [Optional] Two different Input Jacks are available, each requiring different cabling. Type A ( For use with a system incorporating a master) (Special Order Only) Run 2 core shielded audio cable from the master to the Input Jack. Type B (For use with systems not incorporating a master) Run 6 core cable (or same wire as used for intercom wiring) from Input Jack to the nearest room station. Auxiliary/Lock Outputs [Optional] An additional single core cable is required between all room stations (and master if fitted). Heavy duty Figure 8 cable (18 gauge or better) is to be run from each relay output (via power source if applicable) to each auxiliary device. Note: Clearly tagging all cables at the master or central wiring point is recommended, as this can be extremely helpful in the event of having to isolate a problem such as a damaged cable. 9

12 MAXIMUM LENGTH FOR CABLE RUNS As stated in the previous section the system may be Star Wired from a central point or Loop Wired however the number of stations on a loop is governed by the length of the loop, and also whether or not a standby battery is being used in conjunction with the supply. The table below shows the relationship between the length of a cable run and the number of stations permitted on the run. The length of a cable run is determined from the station to which the Power supply is connected. WITHOUT STANDBY BATTERY WITH STANDBY BATTERY 400 feet - one station on loop 200 feet - one station on loop 200 feet - two stations on loop 100 feet - two stations on loop 130 feet - three stations on loop 70 feet - three stations on loop 100 feet - four stations on loop Note: These maximum distances can be doubled where required by running a fig 8 cable (18 gauge) in parallel with the red & black wires. 10

16 INSTALLATION OF VR102 S Room Stations in Timber Frame Walls Cut hole in wall lining keeping one side of the cut out adjacent to a stud so as to allow for firm fixing. Fit room station housing into cut out and mark positions for wall fixing attachments. Remove housing and cut out a 3/16 1/4 vee for the fixing point of the wing toggle bolt. Pull any cabling through the room station back housing and fit the back housing into the cut out hole securing it with the fixing attachments provided. Strip back the outer white covering of the cable (approximately 3 ), then strip the individual wires (approximately 1/4 ). Firmly fix all bare wires into the appropriate screw terminals. Ensure bare wire from one terminal does not touch the bare wire of another. (See diagram page 17) Secure the front fascia onto the back housing using the four 1/2 screws provided. NOTE: It is suggested that these screws be only partially screwed in until system has been fully tested. Room Stations in Cavity Brick Walls Remove the brick and mortar and insert the wall box ensuring that all cables are first pulled the holes in the rear of the wall box. Installation is then the same as for timber frame walls except for using another wood screw instead of the wing toggle bolt. (See diagram page 16) 14

23 INSTALLATION OF MASTER (SPECIAL ORDER ONLY) Timber Frame Wall Not Yet Lined Install the master wall box flush with the front of the stud and brace to limit any movement of the box when fitting the master station. it so as After the wall has been lined, cut out an opening to the inside dimensions of the wall box. Timber Frame Wall Already Lined Cut out an opening in the wall lining (H 12 ¾ x W 10 5/8 ) ½ away from a wall stud. Slide in the master wall box side ways, then straighten it up and firmly nail it to the stud so that it is flush with the front of the stud. Pull the cables through the wall box. Strip back approximately 6 of the white insulation from all the Valet Intercom cables. Twist the wires together according to their colours and trim to equal length. Strip back to bare wire approximately 1 ¼ off the end of each of the individual coloured wires and twist the bared wires together according to their colours. Cut 4 sections of multistrand single core cable, strip one end of these sections to 1 ¼. Twist one of these to each of the coloured groups of intercom cable. Solder and insulate the connections Strip and firmly twist the other end of each of the single core multistrand cables, and screw into the appropriate terminals at the rear of the master. Terminate Aerial, Power Supply, Input Jack and Auxiliary Control wires where applicable. Ensure all outer shield wires are insulated and terminated at the appropriate terminal.

26 POWER SUPPLY Requirements A Regulated 13.8V DC power supply is required to power the system. The required current rating of the supply will vary depending on the size of the system and is equal to the sum of the current draw of each unit used. CURRENT DRAW - MASTER ma peak - S ma peak - AUX O-P BOARD - 60 ma per board An 800 ma power supply will operate a system comprising of 5 Room/Door Stations. A 2 Amp power supply will operate a system comprising of 13 Room/Door Stations. (or a Master and 11 Room/Door Stations) A 3 Amp power supply will run A Master and 17 Room/Door stations. Multiple Supplies Multiple power supplies may be used to provide additional current however their output voltages need to be identical to minimize power losses. Standby Battery (Optional) Many 13.8 V power supplies accommodate the use of a standby battery which may be used to allow the entire system to run in the event of a mains power fail. The duration of battery backup is dependant upon: a) the size of battery(s) used b) the number of stations connected A system using a 12V 6.5AH battery with ten stations connected to a master, will run for approximately three hours with music playing at a moderately high volume. (six hours with music turned off) 24

27 Installing Power Supply Attach figure 8 wire from the master to the output of supply ensuring that polarity (+ve & -ve) is correct. NOTE: The trace on the output wires of a transformer cannot be relied upon to indicate +ve & -ve. Always use a multimeter to check polarity before making the final connection. The maximum length for cable runs is reduced if using a standby battery due to the battery having a lower output voltage than the power supply itself. (See section Maximum Lengths for Cable Runs ) If Battery Backup is required on a system using multiple supplies, each supply is to have its own battery. 25

28 CONTROL VOLTAGE LOAD RESISTOR The fitting of a Load Resistor to the system is required to balance the Voltage Control Line so that communication is received by the appropriate station(s). Although a Load resistor is provided with each Room Station Only One Load Resistor is required for an entire system. The Load Resistor should be fitted at the Master Station across the Yellow - Voltage Control terminal and the Shields - 0V terminal. In systems where a Master Station has not been installed, the Load Resistor should be fitted at the Room station where the power supply has been connected, across the VLC (YEL) terminal and the Neg (BLK) terminal.

29 CODING - VR102 For the purpose of Select Calling (Calling individual or grouped stations), each station must be allocated either a Single Digit or Double Digit number. If more than one station is allocated the same number, the stations having the same number will form a group. Allocating a number to a station, is done by means of programming via the keypad. Single Digit Coding Single Digit Format is the default programming setting intended for systems requiring up to 8 select call channels. This format offers the convenience of calling individual stations by pressing only one button. NOTE: Single Digit Format is compatible with the Current Master (VM101) and previous model Room Stations (VR101). Enter program mode by pressing the PRIVACY and MONITOR buttons simultaneously. If not previously programmed the station will already be in the default setting of Single Digit Format where the red LED will repeatedly flash the programmed number. (the default number being 1) Enter a number between 1 and 8 by pressing the corresponding button. The Red LED will repeatedly flash the programmed number. Exit program mode by pressing the CANCEL/CLEAR button. NOTE: The Master Station can only be set to 1 or 2 and is factory set to 1 (See section USING TWO MASTERS) 27

30 Double Digit Coding Double Digit Format is a programming option intended for systems requiring from 9 to 24 select call channels. This format requires that two buttons be pressed in sequence for calling individual stations. Note: Double digit format is not compatible with the Current Master (VM101) and Previous model Room Stations (VR101). Enter program mode by pressing the PRIVACY and MONITOR buttons simultaneously If not previously programmed the station will be in the default setting of Single Digit Format where the red LED will repeatedly flash the programmed number. (the default number being 1) Press the AUX button to toggle to Double Digit Mode. In Double Digit mode the red LED will repeatedly flash the following information. - Two quick flashes representing Double Digit Mode - One to three flashes representing the first digit (default = 1) - One to eight flashes representing the second digit (default = 1) Enter a double digit number in the ranges of 11 to 18, 21 to 28, 31 to 38. (24 possibilities in total) The red LED will repeatedly flash the following information. - Two quick flashes representing Double Digit Mode - One to three flashes representing the first digit of the new number - One to eight flashes representing the second digit of the new number Exit program mode by pressing the CANCEL/CLEAR button. Note: - Single and Double Digit format cannot be mixed in one system. - Each station is to be individually programmed to the same format. - Repeated pressing of the AUX button while in program mode will toggle between Single and Double Digit formats. KEYPAD BACKLIGHTING Model VR102 Room Stations have Keypad backlighting which can be enabled and disabled by pressing the DOOR button while in Program mode, as outlined above. 28

31 DOOR ADJUSTMENTS There are three adjustments on the door station which may require fine tuning after installation. NOTE: A flat bladed screw driver with a blade width of between 2mm and 2.4mm is required for these adjustments. The use of an incorrect screw driver will result in the pot being damaged. Door Station Volume Speaker volume at the door station is adjusted by means of a miniature trim pot (VR1) located in the center of the circuit board. Turning this pot will vary the speaker volume. This adjustment can be made while someone is communicating to the door station from one of the internal stations or while the chime is activated. Chime Volume Chime volume is adjusted by means of a miniature trim pot (VR2) situated at the bottom of the circuit board as indicated below. Turning this pot will vary the chime volume throughout the system. This pot should be adjusted so the chime volume comes through at an acceptable level at an internal room station with its slide volume control set to around level 4 or 5. Microphone Gain The microphone gain pot (VR3) is generally set half way and would rarely require adjustment. The microphone level can be turned down where the door station causes feedback in a room station due to close proximity or can be turned up if the communication level at internal stations is too low.
