Sounder (Siren) Connections; Wiring The Ac Transformer - Honeywell ADEMCO VISTA-12A Installation And Setup Manual

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
2-5 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.

Mounting and Wiring the Control

Wiring the AC Transformer

Transformer:
Connect the Transformer to terminals 1 and 2
on the control board. See wiring table at bottom
of page for wire size to use.
Use wired-in or plug-in 110 (e.g., 1321)/220VAC
transformer, with 16.5VAC, 25VA output.

V/99090/E148-36
Using Powerline Carrier (X-10) Devices
If using Powerline Carrier (X-10) devices, a
separate powerline modulator must be used,
which is connected to the supplied Trigger
Module via an SA4120XM-1 cable. See your
local distributor for available modulators and
connecting cable.
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.
