7.7 SGM-1004A Hardwire NAC Signal Adder Module
Figure 24 Hardwire NAC Signal Adder Module (SGM-1004A)
7.7.1 SGM-1004A Components
There are four green LEDs on the board, one for each signal zone. The LED will illuminate or
flash following the NAC signal rate sent to its zone. It will be off when the system is normal and
they will illuminate when a NAC signal zone is activated. The LED does not reflect what is
happening on the NAC signal zone, just that it is receiving data to activate that NAC signal
zone.
JW1 Remove continuity jumper if this is not the last adder module installed.
JW2 Jumper pins for bell cut or isolators on Zone 1.
JW3 Jumper pins for bell cut or isolators on Zone 2.
JW4 Jumper pins for bell cut or isolators on Zone 3.
JW5 Jumper pins for bell cut or isolators on Zone 4.
JW11 For basic operation do not wire these terminals.
Note: Jumpers JW2, JW3, JW4 and JW5 are positioned on pins 2 and 3 (right two pins
with board orientation as shown above) from factory.
