Step 1: Module Placement & Verification
A. Move the Programming Slide Switch to the ‘on’ position (up). The System
Trouble LED will begin to flash and the Trouble Buzzer will sound at 20
ppm (pulses per minute).
B. Press the Reset Button. All the panel LEDs will turn on and then turn off.
After about 15 seconds the green power LED will begin a single phase
flash (flash and pause, flash and pause, etc.) the System Trouble LED
will turn a steady amber and the Zone Trouble LED’s will turn to a steady
amber.
C. At this point all Zone Trouble LED’s should be a steady amber, as well as
any Expansion Modules Enable/Disable LED.
Step 2: Initiating Device Circuit Programming
A. Press the Reset Button. The green power LED will begin a two phase flash
(flash-flash-pause, flash-flash-pause, etc.), the Zone 1 Trouble LED will
turn to steady red and the Circuit 1 and Circuit 2 Signal Trouble LED’s will
turn a steady amber.note 1
B. Use the Trouble Silence Button to step through the different zone types.
The different zone types as well as their Zone Trouble LED Color Codes
are listed in the following chart.
Initiating Device Circuit Zone Type Zone Enable/Disable LED Color Code

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

Technical Bulletin # 970510 Page 4of 7
single phase flash (flash-pause, flash-pause, etc.) and the Circuit 1 Signal
Trouble LED should be on steady amber. note 2
B. Press the Alarm Silence Button to chose the Indicating Appliance Circuit 1
(SIG 1) as Silenceable or Non-Silenceable.
Indicating Appliance Circuit Mode Alarm Silenced LED Code
Silenceable Single Phase Flash Amber (flash-
pause, flash-pause, etc.)
Non-Silenceable OFF
C. Press the Trouble Silence Button to chose the desired Indicating Appliance
Circuit output signal rate. The Indicating Appliance Circuit Output Rate and
their Signal Circuit Trouble LED codes are listed in the following chart.
Indicating Appliance Circuit Output Rate Signal Circuit Trouble LED Code
Continuous Steady
120 Pulses per minute 120 Flashes per Minute
Temporal (3-3-3) Flash-Flash-Flash-Pause and repeat
Continuous California Rate 10 seconds ON, 5 Seconds OFF…
March Time California Rate 10 Seconds ON @ 120 PPM, 5
Seconds OFF…
D. After Circuit 1 is programmed press the Reset Button. The Alarm Silenced
LED should be performing a single phase flash (flash-pause, flash-pause,
etc.) and the Circuit 2 Signal Trouble LED should be on steady amber.note3
E. Repeat steps B and C.
F. After Indicating Appliance Circuit 2 has been programmed, press the Reset
Button.
note 2The Alarm Silenced LED will be performing a single flash, unless it was previously
programmed as Non-Silenceable. The Circuit 1 Signal Trouble LED will be a steady amber,
unless it was previously programmed for a different output rate.
note3The Alarm Silenced LED will be performing a single flash, unless it was previously
programmed as Non-Silenceable. The Circuit 2 Signal Trouble LED will be a steady amber,
unless it was previously programmed for a different output rate.
