Make sounder connections to alarm output terminals 3 (+) and 4 (–).

•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.

Supervised output

1.Cut the red Bell Supervision Jumper located above terminals 2 and 3 on the PC board.

2.Connect a 2k ohm resistor across the terminals of the last sounder. See Figure 5.

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..

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.

Connect keypads and other addressable devices (4204, 4219, 4229, 4286, 5881, LRR, etc.) to the control’s keypad terminals as shown on the Summary of Connections diagram. The system supports up to 8 keypads, which can be assigned to partitions in any combination (see program fields *190-*196).

Determine wire size using the Wire Run Chart on the following page. For single 4-wire runs, determine the current drawn by all units, then refer to the Wiring Run chart to determine the maximum length that can be safely used for each wire size.

Supplementary Power (optional)

UL Use a UL Listed, battery-backed supply for UL installations. The battery supplies power to these keypads in case of AC power loss.

The battery-backed power supply should have enough power to supply the keypads with the UL required minimum standby power time.

Use supplementary power if the control’s aux. power load for all devices exceeds 600mA (suggested power supply: AD12612). Connect as shown in Figure 6. Be sure to connect the negative (–) terminal on the power supply unit to terminal 4 (AUX –) on the control.

IMPORTANT: Keypads powered from supplies that do not have a backup battery will not function if AC power is lost. Make sure to power at least one keypad in each partition from the control’s auxiliary power output.
