The following features are available in CPU EPROM U4 software numbered 73265 (or greater).
The
AUTO SILENCE
feature will automatically turn off all silenceable circuits after a pre-programmed delay. The delay
timer starts after a system alarm. Any subsequent alarms which occur before the auto silence activates will restart the delay
countdown at zero.
The
PRESIGNAL DELAY
delays the activation of all silenceable circuits mapped to a zone in alarm for a pre-programmed
length of time. A subsequent alarm aborts the delay and re-maps all alarm points. Pressing the SIGNAL SILENCE switch
before the delay time has expired aborts the delayed activation of the silenceable circuits.
Note: When Pre-Signal Delay
has been selected, at least one notification appliance circuit must be programmed as non-silenceable. This will
ensure that at least one notification circuit will sound immediately after initiation of an alarm condition.
The
POSITIVE ALARM SEQUENCE
(PAS) function adds a timer. After a first alarm, the timer is set for 15 seconds. If
nothing happens in that 15 seconds, all signals are activated. If an ACKNOWLEDGE or SILENCE key (including annuncia-
tor keys) is pressed before 15 seconds, the timer changes to its full value (1, 2, or 3 minutes).
Note:
When Pre-Signal has been selected, at least one notification appliance circuit must be programmed as non-silenceable.
This will ensure that at least one notification Circuit will sound immediately after initiation of an alarm condition.
NFPA 72-1993 requires the installation of a Day/Night/Weekend switch that can override PAS operation. This can be
accomplished by using a normally open switch to close an IZ-8F that has been programmed for NON-ALARM and SUPER-
VISORY operation. Note that the zone cannot have a notification appliance circuit mapped to it.
The switch totally inhibits all presignal function. On entering presignal mode, the CPU checks zone 1 in module 1. If this is
an IZ-8F zone set for NON-ALARM and SUPERVISORY, and it is
active
(switch is on), all presignal and PAS operation
will be ignored.
AC LOSS REPORT DELAY
When a Digital Alarm Communicator Transmitter (DACT) is used, the reporting of an AC
Loss condition must be delayed. With software P/N 73452 (or higher), this function can be selected under extended pro-
gramming features. When selected, the CPU's trouble contacts will not be activated for loss of AC power until approxi-
mately 8 hours after loss of power occurs.
The
CALIFORNIA CODE
mode adds a ten second timer to the two notification circuits on the CPU. When an alarm
occurs, the timer is started. At the end of the ten second period, all silenceable circuits are shut off for five seconds. NOTE:
The circuits on the CPU and the circuits on the IC-4F are controlled by different microprocessors and may not be in
synchronization with each other. At the end of the five seconds, the circuits are turned on again for 10 seconds. This cycle
repeats indefinitely.
In the event of an acknowledged alarm, the
REMINDER
mode pulses the piezo every 15 seconds. If an acknowledged
trouble exists, but not an alarm, the piezo will beep every two minutes.
