Sounder (Bell) Connections
1. Make sounder connections to alarm output terminals 3
(+) and 4 (–).
For supervised output, continue with steps 2 and 3.
2. Cut the red Bell Supervision Jumper located above
terminals 2 and 3 on the control board.
3. Connect a 2k ohm resistor across the terminals of the
last sounder.

Notes
This control complies with NFPA requirements for
temporal pulse sounding of fire notification appliances.
Temporal pulse sounding for a fire alarm consists of:
3 pulses – pause – 3 pulses – pause – 3 pulses–etc..
•
The 12VDC sounder output activates when an
alarm occurs.
•
Total current drawn from this output cannot
exceed 2 amps (going beyond 2 amps will
overload the power supply, or may cause the
electronic circuit protecting the sounder output to
trip).
•
You must install a battery, since the battery
supplies this current.
UL
•
Use only UL Listed sounding devices for UL
installations.
•
Bell supervision is required for fire alarm installations.
•
The total current drawn from the alarm output and the
auxiliary power output, combined, cannot exceed 600
mA. In addition, the sounding device must be a UL
Listed audible signal appliance rated to operate in a
10.2-13.8 VDC voltage range, and must be mounted
indoors.
Wiring the AC Transformer
1321 Transformer:
Connect the 1321 Transformer to terminals 1 and 2 on
the control board. See Wire Run Chart at right for wire
size to use. (Use 1321CN in Canada)
1361X10 Transformer
(required if using Powerline Carrier devices)
1. Splice one end of a 3-conductor cable to the wire ends
of the SA4120XM-1 Cable.
2. Connect the SA4120XM-1 cable plug to the 8-pin
connector on the control (see the Summary of
Connections diagram for location of the 8-pin
connector).
3. Connect the other end of the 3-conductor cable to the
1361X10 Transformer, as shown.
Canada: See Powerline Carrier Device section for
connections to the PSC04 X-10 Interface and trigger pins.
Notes
•
Use caution when wiring the transformer to the
control to guard against blowing the transformer
fuse (the fuse is non-replaceable).
•
Wiring to the AC transformer must not exceed
250 feet using 16 gauge wire. The voltage
reading between terminals 1 and 2 of the
control must not fall below 16.5VAC or an “AC
LOSS” message will be displayed.
•
Do not plug the transformer into the AC outlet
while making any wiring connections to the
control. As a safety precaution, always power
down the control when making such connections.
