Sounder (Bell) Connections - ADT Safewatch Pro 3000EN Installation And Setup Manual

3000EN Series: Installation Instructions
U L
Use a UL Listed, battery-backed supply for UL installations. The battery supplies power to these touchpads in
case of AC power loss.
The battery-backed power supply should have enough power to supply the touchpads with the UL required
minimum standby power time.
Touchpads 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 touchpad in each partition from the control's auxiliary power output.

* Includes Touchpads, RF Receivers, Zone Expander/Relay Units, 4286 Phone Module and communication device. Maximum wire
lengths for any device that is homerun to the control can also be determined from the Wiring Run Chart, based on the current
draw of that device alone.
The length of all wire runs for both partitions combined must not exceed 1500 feet (457m) when unshielded quad conductor cable is
used (750 feet if shielded cable is used). This restriction is due to the capacitive effect on the data lines when quad cable is used.

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 terminal 5 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.
U L
• 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 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.
