Figure 19: Hardwire Signal Adder Module (SGM-1004A)
GREEN SIGNAL LEDs
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.
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.
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.
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 second mode provides 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.
Isolator Mode
Jumpers for the Isolator Mode
JW2: Place jumper over pins 2 and 3 for the ability to connect an isolator on Zone 1.
JW3: Place jumper over pins 2 and 3 for the ability to connect an isolator on Zone 2.
JW4: Place jumper over pins 2 and 3 for the ability to connect an isolator on Zone 3.
JW5: Place jumper over pins 2 and 3 for the ability to connect an isolator on Zone 4.
ATTENTION: Discard jumpers on zones that are not configured for isolators.
J11: Wire these terminals to an alarm relay. These may be tapped if more signal modules are used in this manner.
