Definitions:
Alarm Verification - After receipt of an alarm by a smoke detector, verified
Zones attempt to automatically reset the detector. Receipt of a second alarm
within the 60-second confirmation period after the automatic detector reset
period transmits the alarm to the panel.
Waterflow Zone - Initiating Device Circuits defined, as waterflow zones do not
permit alarm silence while the alarm is active.
Waterflow Zone with Retard - Initiating Device Circuits defined as waterflow
with retard do not permit alarm silence while the alarm is active and also delay
the waterflow signals to the panel to prevent false alarms due to fluctuations in
water pressure.
Alarm Non-Verification - As soon as a device on this type of zone goes into
alarm, an alarm is transmitted to the panel.
Supervisory Operation - An Initiating Device Circuit used to monitor the
status of critical fire protection equipment (e.g., Tamper switches for a sprinkler
system).
C. Once an Initiating Device Circuit Zone Type is selected, the Indicating
Appliance Circuits (IAC’s) operated by this zone must be chosen. This is
indicated by the Circuit 1 and Circuit 2 Signal Trouble LED’s. If both LEDs
are steady amber, then both SIG 1 (Circuit 1) and SIG 2 (Circuit 2) are
operated by that zone (This is the Factory Default.). If only Circuit 1’s
Signal Trouble LED is on then only SIG 1 (Circuit 1) is operated by this
zone. If only Circuit 2’s Signal Trouble LED is on then only SIG 2 (Circuit
2) is operated by this zone. Press the Alarm Silence Button to change the
Indicating Appliance Circuit operated by this zone.
D. To program the next Initiating Device Circuit, press the Reset Button and
repeat steps B and C above.
E. After the last Initiating Device Circuit has been programmed press the
Reset Button.
Step 3: Indicating Appliance Circuits Programming
A. The green power LED should be performing a three-phase flash (flash-
flash-flash-pause, flash-flash-flash-pause, etc.). The System Trouble LED
should be steady amber, the Alarm Silenced LED should be performing a
