Installation Instructions
Sounder (Siren) 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 Siren 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.
Figure 5. Sounder Wiring (Supervised)
Wiring the AC Transformer
Transformer:
Connect the Transformer to terminals 1 and 2 on the
control board. See wiring table at right for wire size to
use.
Use wired-in or plug-in 110 (e.g. 1321)/220VAC
transformer, with 16.5VAC, 25VA output.
2-4
Notes
The 12VDC sounder output activates when an
alarm occurs.
Total current drain 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 activate).
You must install a battery, since the battery
supplies this current.
Do NOT perform steps 2 and 3 if using a self-
activated siren.
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
76m using 1.2mm O.D. 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 connect to AC mains power while making
any wiring connections to the control. As a safety
precaution, always power down the control when
making such connections.
