Sounder (Siren) Connections - Honeywell Ademco Vista-12D Installation And Setup Manual

* Includes Keypads, RF Receivers, Zone Expander/Relay Units, or TeleCommand Phone Module.
Maximum wire lengths for any device that is wired directly to the control can also be determined from the Wiring Run
Chart, based on the current drain of that device alone.
The length of all wire runs for all partitions combined must not exceed 457m when unshielded quad conductor cable
is used (228m if shielded/screened cable is used). This restriction is due to the capacitive effect on the data lines
when quad cable is used.

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.

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.
