Installing A Keyswitch - Honeywell ADEMCO VISTA-48A Installation And Setup Manual

Installation Instructions
Transmitter Battery Life
• See Wireless Transmitter paragraph in the Limitations of This Alarm System statement located at the end
of this manual for information on transmitter battery life.
• Some transmitters (e.g., 5802 and 5802CP) contain long-life but non-replaceable batteries, and no battery
installation is required. At the end of their life, the complete unit must be replaced (and a new serial number
enrolled by the control).
• Button-type transmitters (such as 5801, 5802, and 5802CP) should be periodically tested for battery life.
• The 5802MN, 5802MN2, and 5804 Button Transmitters have replaceable batteries.
Do not install batteries in wireless transmitters until you are ready to enroll during system programming.
After enrolling, batteries need not be removed.

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 switchplate
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 N.O. 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).
• 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).
