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 as indicated
in Figure 2-7.
3.
Connect a 1k ohm resistor across the terminals of
the last sounder, not across the control's terminals.
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.
• Use only UL Listed sounding devices for UL installations mounted indoors.
U L
• The total current drawn from the alarm output and the auxiliary power output, combined, cannot exceed
600mA. 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
Wire the 1321 Transformer to terminals 1 and 2 on the
control board. Refer to wiring table at right for wire
gauge to use.

NOTES:
•
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.

OHM RESISTOR ACROSS THE EXTERNAL
SOUNDER, AS SHOWN BY THE DASHED LINE.
DO NOT CONNECT THE RESISTOR AT THE
ALARM OUTPUT TERMINALS THEMSELVES!
