Installing A Keyswitch - Honeywell ADEMCO VISTA-12A Installation And Setup Manual

Installation and Setup Guide

Installing a Keyswitch

1. Connect the 4146 keyswitch's normally open
momentary switch to a zone's terminals
(zones 2-8). Remove the 2000 ohm EOL
resistor if connected across the selected zone.
2. Using a standard keypad cable as shown:
Connect the yellow and white keyswitch wires
to trigger connector pin 3 (+12V).
Connect the Red and Green LED wires to the
appropriate output 17/output 18 trigger
connector pins.
3. Connect a 2000 ohm EOL resistor across the
momentary switch.
4. You can wire an optional closed-circuit
tamper switch (model 112) in series with the
zone. If the switch plate is then removed from
the wall, the tamper will open, disabling
keyswitch operation until the system is next
disarmed from the keypad.
If the tamper is opened when the system is
armed, an alarm will occur.
Notes
• Use 4146 keyswitch or any normally open
keyswitch.
• Use only one keyswitch per partition.
• If using a keyswitch in more than one partition,
you must use relays (not the on-board triggers)
for the Red/Green LED functions (step 2).
2-14
• When using a keyswitch, the zone it is
connected to is no longer available for use
as a protective zone.
• Use *56 Menu mode to program the
keyswitch zone and assign it zone type 77.
• Use *80 Menu mode to program the LED
functions: program outputs 17 and 18 for
system operation zone type 78 (red LED)
and 79 (green LED) as appropriate (see
Output Device Programming section).
