Installation Instructions
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.
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

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.
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.

•Use caution when wiring the transformer to the control to guard against blowing the transformer fuse (the fuse is
•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.
Backup Battery
1.Place the
2.After all connections to the control are completed and AC power has been applied, connect the red and black flying leads on the control board to the battery. Do not attach these leads to the battery terminals until all connections are completed.
IMPORTANT: The panel will not power up initially on battery power only. You must plug the transformer in first, and then connect the battery.
UL For UL installations and Residential fire installations, refer to the chart below for the correct battery size required to meet the mandatory standby time.
