Installation Instructions
PC4612 
1. Introduction
The PC4612(A) is a 12-zone annunciator for use with PC4010/PC4020 
security systems. You can install a combined total of 9 PC4612(A) and 
PC4216 modules on each PC4010/4020 system.
2. Specifications
• Style PC4612 or PC4612A available
• 16 programmable LEDs
• Four wire (QUAD) hook-up to Combus
• Nominal current draw of 15mA
• Tamper and trouble reporting
• Supervision by control panel via Combus
3. Installation
Connect the PC4612(A) to the panel via the Combus. Be sure to include the current draw of the PC4612(A) (15mA) in your Combus current calculation. Refer to your PC4010/4020 Installation Manual for 
more information on Combus wiring.
4. Enrolling and Programming the PC4612(A)
Follow the instructions below for enrolling and programming your 
PC4612(A) module. If you are enrolling the module on a PC4010/4020 
v3.0 or greater system, you can use the reference numbers (indicated 
by the square brackets, eg. [0200]) to jump to a programming section. 
Refer to your system's installation or programming manual for more 
information on programming.
4.1 Enrolling
You must enroll the PC4612(A) module with your panel before you 
can program it. The PC4612(A) is enrolled exactly as if it were a 
PC4216 module. Follow these steps:
1. At a PC4010/4020 system LCD keypad, enter Installer's Programming ([*][8][Installer’s code]).
2. Enter Ref #[0200][*] OR scroll to Module Hardware, press [*], 
then, scroll to Enroll Module, press [*].
3. Scroll to PC4216 Module, press [*]. The LCD keypad displays 
Create Tamper on Desired Unit.
4. Tamper and then restore the PC4612(A): 
a) Remove the screws on the bottom of the unit. 
b) Pull the front plastic of the unit approximately Ό" away from 
the backplate. 
c) Replace the front of the unit and the screws in their original 
locations. The LCD keypad displays PC4216 Mod 01 Enrolled.

5. Record the module number in the worksheet area on the back of 
this instruction sheet.
6. To exit Module Enrollment, press [#].
4.2 Programming
On the PC4612(A), each of the 16 outputs controls a particular LED. Outputs 1-12 control the LEDs which light up numbers 1-12 on the Annunciator. Outputs 13-16 control the LEDs which light up the Zone Trouble, 
Bell Trouble, System Trouble and AC On indicators, respectively.
A Custom Group is a set of 16 programming choices which correspond 
to the 16 programmable outputs on each PC4612(A) module. Each 
LED will function according to the programming of its output in the 
assigned custom group.
To program the PC4612(A), you need to assign a custom group to the 
module, and to make sure that the outputs of the assigned custom 
group are programmed appropriately. Example: the PC4612(A) is assigned to custom group (01). In this custom group, output (05) is programmed to follow zone
(020), which is a fire zone. This was done by programming output (05) 
for option (22) zone follow. When zone (020) is in alarm, LED 5 turns 
on. When zone (020) is restored and a fire reset is performed, LED 5 
turns off.
The PC4612(A) uses the same programming as the PC4216, and is 
therefore done in the same programming sections. These sections are 
described below as they relate to the PC4612(A). For instructions on 
how to program the PC4010/4020 and its modules, refer to your 
PC4010/4020 Installation Manual. For information on programming 
PC4216 modules, refer to your PC4216 Installation Instructions.
1. Choose a Custom Group
Ref #: [000703XX] where XX = 01-09 (PC4612(A) number) Program 
each PC4612(A) to use one of nine custom groups. More than one module may follow the same custom group. Enter the number of the custom 
group the PC4612(A) will follow (enter 01-09). To exit, press [#].
2. Program a Custom Group
Ref #: [000704XX] where XX = 01-09 (Custom Group 01-09) A custom group is a set of 16 programmed output options. Each output in a 
custom group can be programmed to operate according to a different 
output option.
1. Choose the output to be programmed (01-16)
2. Enter the number of the output option to be used for that output.
3. To exit, press [#].
Please refer to the System Installation Manual for information on limitations regarding product use 
and function and information on the limitations as to liability of the manufacturer.

The recommended output options for the PC4612(A) are (21), (22), 
(48), (55), (56), (57). Their descriptions are listed below.
4.3 Recommended Output Options
Zone Alarm (21)
For zones that are programmed as burglary, the zone alarm output will
activate the LED when the selected burglary zone has gone into 
alarm.The LED will remain on until the partition is armed again.
Zone Follow (22)
For zones that are programmed as Fire or Fire Supervisory, the zone 
follow output will turn on the LED when the fire zone is in alarm, or 
when the fire supervisory zone is off-normal (zone shorted). The LED 
will only turn off when the zone has been restored and a fire reset has 
been performed.
Outputs 1-10 have red LEDs and are intended for fire/burglary alarm 
zone annunciation. Outputs 11-12 have yellow LEDs and are intended 
for fire supervisory zone annunciation.
NOTE: Use Options 21 or 22 for output numbers 01-10 and option 22 
only for output numbers 11-12.
Fire Zone Tbl. (48)
The output will activate when a fire zone is bypassed, or when a fire 
zone trouble condition is detected. The output will deactivate when the 
zone is unbypassed or the trouble is restored. Use this option for 
PC4612(A) output number 13.
Common Fire Tbl. (55)
The output activates when any of the following troubles are detected 
by the panel. The output deactivates when the trouble is cleared: 
• Any system AC or battery trouble (PC4020, PC4820, PC4204, 
PC4701)
• Any system communicator trouble (TLM1, TLM2, FTC, LINKS)
• Ground Fault trouble
NOTE: Use this option for PC4612(A) output number 15.
Bell Trouble (56)
The output activates for a trouble (open or short) on any supervised 
system bell output (PC4010/4020 or PC4702). The output deactivates 
when the trouble is cleared. Use this option for PC4612(A) output 
number 14.
AC Status (57)
The output will be ON when AC power is present on the PC4010/ 
4020, as well as all enrolled modules (PC4204, PC4820, PC4702). If 
the PC4010/4020 or any module loses AC power, the AC Fail Delay 
timer will start (see your PC4010/4020 Installation Manual for more 
information). When the timer expires (or if it is programmed to be 0), 
if the AC is still missing, the output will turn OFF. An AC Fail trouble 
condition will be generated. When AC power is restored, the output 
will again wait for the AC Fail Delay timer to expire. If the AC power 
is still on at the end of the delay, the output will turn ON. Use this option for PC4612(A) output number 16.
4.4 Finishing
Make sure you label each of the 12 zone lights in the space provided 
on the annunciator. When you have finished installing and programming the PC4612(A), instruct the end-user of the system how to interpret events using the annunciator.
