Figure 13 Signal Adder Module (Model SGM-1004A)
Jumpers
JW1: Remove continuity jumper if there are any more adder modules installed.
JW2: Jumper pins for bell cut on Zone 1.
JW3: Jumper pins for bell cut on Zone 2.
JW4: Jumper pins for bell cut or on Zone 3.
JW5: Jumper pins for bell cut or on Zone 4.
J11: Wire these terminals to a bell cut relay (for details see QRM-1001 Bell Cut Module Installation and Operating
Instructions, LT-666).
Components
There are four green LEDs on the board, one for each signal zone. A green LED will illuminate or flash following the
signal rate sent to its zone. It will be off when the system is normal and it 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.
Operation
There are three modes of operation for this module. The basic mode of operation does not involve any bell cut relay
or 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 bell cut operation,
which allows the silencing of the bells. The third 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.
Notes:
• Jumper JW6 on the main fire alarm module must be removed if there are any adder modules installed.
• The SGM-1004A requires 4 display points.
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.
