1. Field 15 to assign the keyswitch to a partition (1-2), or (9) to silence fire bell if fire
alarm occurs; enter 0 to disable.
2. Zone 7 must be assigned a non-zero response type.
3. Field 3 20 must be set to 1 when using J2/OUT 1 and 5 to operate keyswitch ARMED
and READY LEDs (if keyswitch provides LEDs).
4. 40 to enable Open/Close report for keyswitch.
Wire the keyswitch as shown in Figure 12-3. The tamper switch need not be used for fire or
UL Household Burglary installations. For UL Commercial Burglary installations, the
tamper switch must be wired to zone 8, and zone 8 must be programmed for Day
Trouble/Night Alarm (zone type 5). When the keyswitch is removed from the wall, the
tamper switch will open, causing an alarm or trouble on zone 8, and causing the control to
disable keyswitch operation until the associated partition is disarmed from a keypad.
Keyswitch Operation
The VISTA-32FB allows two modes of keyswitch operation. When field 15 is set to a
partition (1-2), the keyswitch operates as follows:
With System Disarmed and No Alarms Present
A momentary short across zone 7 will arm the partition in the AWAY mode, and a short held
for more than 10 seconds will arm the partition in the STAY mode. A subsequent short will
disarm the partition. The keyswitch LEDs will indicate that the partition has armed (see
table below).
Faulted zones must either be corrected or bypassed before the system will arm.
In commercial fire installations, mount the keyswitch next to a keypad. The keypad will display the
U L
UL-required FIRE BELL SILENCED indication when the keyswitch is used to silence a fire alarm.
TO OUT 1 (J2 PIN 7)
TO GND (J2 PIN 8)
TO OUT 5 (J2 PIN 6)
TO ZONE 8 + (TERM 27)
TO ZONE 7/ZONE 8 – (TERM 26)
TO ZONE 7 + (TERM 25)
