Signal Circuit
Restore
A. Restore On - ACKNOWLEDGE
For use with supplementary signaling and
functions
Any active output point programmed to restore on ACKNOWLEDGE will
return to Idle whenever the Acknowledge switch is pressed. All output
points that were returned to Idle will reactivate upon a subsequent alarm
which is programmed to activate those output points.
B Restore On - SIGNAL SILENCE (** System Default **)
All required Fire
Alarm outputs in which silence is intended to occur, shall be programmed under
this switch or function.
Any active output point programmed to restore on Signal Silence will be
silenced by the activation of the Signal Silence Switch and will return to
Idle. The Signal Silence Switch operates as an alternate acting switch. All
outputs that were returned to idle will reactivate upon a subsequent alarm or
by depressing the Signal Silence Switch again. Both Signal Circuits and
Relay Outputs can be programmed to restore on Signal Silence. . All output
points that were returned to Idle will reactivate upon a subsequent alarm.
C. Restore On - RESET
Serves as System Back up. Any active output point not restored by any
other means will restore on RESET. Any active output programmed to
restore on RESET will not restore on any other action.
>>
NOTE: There are a few restrictions to be aware of regarding
output signal circuits:
1. The two signal circuits on the Bus Driver Module (BDM) can be
used for steady or pulsing DC (marchtime, temporal, etc.) and
programmed separately.
Alarm Levels
Available
There are four levels of alarm that can be assigned to each type of output
circuit, PreAlarm, 1st Alarm, 2nd Alarm or Releasing. These levels
designate at which level of alarm an output circuit will activate. Output
circuits assigned to 1st alarm level (system default) will activate when a first
alarm is detected on its assigned input circuit(s), provided the input circuit is
assigned to activate that output circuit in the CBE table. Circuits designated
as PreAlarm will activate when a prealarm level is detected on an input
circuit. Circuits requiring activation on 2nd alarm (AND zones) can be
assigned to alarm level 2. An AND zone assigned to activate both 1st and
2nd alarm level output circuits will activate only those outputs assigned to
level 1 during a first alarm condition. When a second alarm is detected both
first and second alarm outputs will activate. A shorting device will activate
both first and second alarm outputs (CZI).Discharge devices are assigned to
Level three, and will activate after the 2
nd
alarm plus the releasing and dump
timing, if not aborted.
