Hardwire Signal Adder Module (SGM-1004A)
5.11.1 Basic Mode
Jumpers on the SGM-1004A Signal Adder Module and their functions:
JW1:
Remove continuity jumper if this is not the last adder module installed.
JW2, JW3, JW4, and JW5:
Leave these jumpers open, on positions 2 and 3.
J11 Terminals:
Not connected.
5.11.2 Components
There are four green LEDs on the board, one for each signal zone. The LED will illuminate or
flash following the signal rate sent to its zone. It will be off when the system is normal and they
will illuminate when a signal zone is activated. The LED does not reflect what is happening on
the signal zone, just that it is receiving data to activate that signal zone.
5.11.3 Operation
There are two modes of operation for this module. The basic mode of operation does not
involve any isolators connected to the signal zones. For this case, leave jumpers JW2, JW3,
JW4 and JW5 as they come on pins 2 and 3, and do not make any connection to terminal
block J11. The isolator mode is used when isolators are to be connected to the signal circuits.
For further information on bell cut relays or isolators, please refer to the specific fire alarm
panel manual or the isolator instruction manual.
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.
