Trigger Module and On-Board Triggers
IMPORTANT: Make all wiring connections to the Trigger
Module before mounting the module to the PC board.
1. Install five standoffs (supplied) as shown below.

(5 PLACES)
2. Connect field wiring to the desired trigger terminal
on the trigger module (TRIG 1 = output 17; TRIG 2 =
output 18) and the VTRIG +12V terminal.
For supervised trigger operation, refer to the
following:
Trigger Voltage/Aux Power Supervision
To supervise trigger voltage and/or aux power:
A. For Aux Power: Use the Trigger Module
terminals for ground and +12V connections
(instead of main board terminals 4 and 5).
For Trigger Voltage: Connect trigger wiring as
described in step 2 above.
B. Connect the SUPV terminal on the Trigger
Module to a zone (+) terminal.
C. Program that zone as a configurable zone type
set as a 24-hour zone and with the desired report
code (CID code 312 is recommended).
3. If using a Powerline Interface Modulator and
powerline carrier devices, use the SA4120XM-1
cable (part of 4120TR Trigger Cable). See previous
Powerline Carrier Device section.
4. Install the Trigger Module by aligning its 8-pin
header over the main PC board’s 8-pin connector
(orient the Trigger Module as shown on the
Summary of Connections diagram), then press down
firmly until the Trigger Module’s standoffs are
seated on the main PC board.
Notes
•
The Trigger module (Trigger-G) provides
supervision of auxiliary power and trigger
power, and provides connections for the two
onboard triggers.
•
There are two on-board triggers that can be
used to activate output devices.
•
These outputs are normally high, and go low
upon programmed condition.
•
The outputs can be programmed for inverted
operation (normally low, go high) using *79
Menu mode.
•
Program these triggers using *80/*81 Menu
modes as you would for any other relay output.
•
When using these outputs, note:
pin 1 = output number 17 (trigger 1):
15 ohms to ground when closed
(output low), open when off (output
high, normal default); can be used to
reset smoke detector power (must set
“output normal low = yes” in *79
Menu mode, and set for zone type 54,
fire zone reset, in *80 Menu mode); or
can support 12V relay module that
draws less than 300mA.
pin 5 = output number 18 (trigger 2):
15 ohms to ground when closed
(output low); open when off (output
high, normal default); or can support
12V relay module that draws less than
300mA.
•
NOTE: Do not exceed 700mA combined
current for both triggers and aux
power. Doing so can damage PC board
components and will void the system’s
warranty.
