2 1 Fire protection: LRAS for shutdown by FireChain & smoke detection LF-DO4 LF-DO4-IP 24 V AC/DC ProgramID: 90:00:00:00:00:0A:04:FB LRAS 4/21 LDO 4 LRAS 4/21 IP65 24 V AC/DC ProgramID: 90:00:00:00:00:8A:04:FB Function: Actuation of relays by. The relays get locked and can be unlocked individually by. Several FireChain channels can be binded in parallel on the inputs. From the storage results a distinct signal to shutdown for example ventilation systems. An individual manual signal can be scanned and a delay time for unlocking can be set. Node Object nvirequest SNVT_obj_request nvostatus SNVT_obj_status The Node Object monitors and controls the functions of the different objects in the device. It supports only the basic functions required by LonMark. FC Object nvifc[0...3] nvofc[0...3] nvirm[0...3] nvifc[0...3] SNVT Type If an type signal is recognized at the respective input nvifc[0...3] this signal is stored. The corresponding nvofc[0...3] is set to the value. If the value changes at the input the output value remains unchanged. By the once-only storage of the input value several FireChain signals can be binded in parallel to one input. The ouput is reset by unlocking (see EntrFC Object). nvirm[0...3] SNVT Type Smoke signal: If an type signal is recognized at the respective input nvirm[0...3] it is issued to nvofc[0...3] and nvokstoer[0...3]. nvofc[0...3] SNVT Type Transmission of FireChain in accordance to the function of the device. When the signal has been recognized and locked at the input the nvofc[0...3] is set to. When the unlocking timer is running emerg_null is controlled on the variable nvofirechain[0...3] as indication for an open state. When the timer is up and no signal was recognized at the input nvifirechain[0...3] the output nvofirechain[0...3] is set to Subject to modifications!

3 2 EntrFC Object nvientrfc[0...3] nvizentrfc nvientrfc[0...3] SNVT Type The respective FireChain channel can be unlocked with the nvientr[0...3]. The stored value is reset with an adjustable timeout period. The respective nvofc[0...3] variable is set to the value of the input (). If a new signal is generated during the timeout period the timeout timer is stopped. As long as the timer is running the output is set to emerg_nul. nvizentrfc SNVT Type All four channels can be unlocked simultaneously by the input nvizentrfc. Stoer Object nvostoerkom nvokstoer[0...3] nvostoerkom SNVT Type Serves to monitor communication. The variable nvostoerkom is set to the value if nvifc[0...3] is not updated within the time set in ncimaxrest[0...3]. nvokstoer[0...3] SNVT Type Single alert signal of the channels. The variable nvokstoer[0...3] is set to the value EMERG_FIRE if the nvifc[0...3] on the respective channel is not updated within the preset ncimaxrest[0...3] or if an EMERG_FIRE signal arrives at the input variables nvifc[0...3] and nvirm[0...3] Subject to modifications!

4 3 Hand Object nvohand nvohand SNVT Type Signal about the position of the manual switches. All switches in automatic mode: nvohand = At least one switch in position 0 or 1 : nvohand = Virtual Function Block ncimaxsendtime ncientrtime[0...3] ncimaxrest[0...3] nciinv[0...3] SNVT_lev_disc ncimaxsendtime SNVT Type The output variables described above are issued after a preset period of time. Value range: 0 timer deactivated 1 to 6553 timer time in seconds (factory setting: 0) ncientrtime[0...3] SNVT Type Delay time for unlocking until the outputs are set. The time serves to to identify for sure if an is still sent in case of a parallel binding. The period has to be set longer than the highest heartbeat time of the binded components. 0 timer deactivated (unlocking not possible!!!) SNVT Type If a value >0 is set by a start timer is activated that will release a once-only central unlocking operation after the preset time in case of voltage recovery. Thus an equipment with motor-driven fire dampers can be reset in a trouble-free automatic mode after a voltage breakdown Subject to modifications!

5 4 ncimaxrest[0...3] SNVT Type Setting of a maximum response time. If nvifc is not updated within this time an alert is issued by nvokstoer. Factory setting: 0 nciinv[0...3] SNVT Type SNVT_lev_disc Operating mode of the output relays can be inverted. nciinv[0...3] = ST_OFF; relay dropped off at nvifc[0...3] = nciinv[0...3] = ST_ON; relay dropped off at nvifc[0...3] = Conduct at voltage recovery or switch-on PowerOn automatic unlocking internal unlocking nvifc ncientrtime emerg_nul nvofc General functional sequence nvientrfc[0] internal unlocking nvifc[0] nvofc[0] ncientrtime[0] emerg_nul Subject to modifications!
