Sounder (Bell) Connections; Wiring The Ac Transformer - ADT Safewatch Pro 3000 Installaton Manual

Safewatch Pro 3000 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.

Wiring the AC Transformer

1321 Transformer:
Connect the 1321 Transformer to terminals 1 and 2 on
the control board. See wiring table at right for wire gauge
to use.
4300/1321X10 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
4300/1321X10 Transformer, as shown.

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
2000
supplies this current.
OHM
EOL
RESISTOR
U L
• Use only UL Listed sounding devices for UL
installations.
• The total current drawn from the alarm output
and the auxiliary power output, combined,
cannot exceed 700 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
ADT3000-011-V0
indoors.
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.
