Fire Alarm Verification for Smoke Detectors
This feature applies to any hard-wired or polling loop fire zone set to zone type
16. For four-wire smoke detectors, the power must be interrupted by the
system's auxiliary relay (field 3*61 = 2). The control panel will “verify” any alarm
by resetting the smoke detectors after the first alarm trigger, and then waiting 90
seconds for a second alarm trigger. If the smoke detector or thermostat does not
trigger again, the control will disregard the first trigger, and no alarm signal will
occur. This feature eliminates false alarms due to electrical or physical transients.
Zone 6 Tamper Configuration
Zone 6 may be used as a tamper loop for the Vista-100 cabinet door tamper
switch and for the Ademco AB12 Grade A burglary bell box tamper switches and
tamper liner. The bell housing's tamper switch and inner tamper linings must
also be wired to zone 6.
Assign zone 6 to a burglary partition. Program zone 6 for Day Trouble/Night
Alarm (zone type 5) when only one burglary partition is used. Program for 24-Hr.
Audible Alarm (zone type 7) when more than one burglary partition is used.
Enable the Zone 6 Alternate Tamper Function (program field 3*17).
When set in this manner, the zone will trigger a trouble when the panel is
disarmed and an alarm when the panel is armed, when the zone senses either
an open or a short, or when an earth ground fault caused by drilling through the
AB12 housing is detected. See the Section 13:
EXTERNAL SOUNDERS for
information on AB12 bell wiring.
Wiring 2-Wire Latching Glass Break Detector s To Zone 8
Use zone 8 for connection of compatible 2-wire latching-type glass break
detectors. Wire as follows:
1. Connect all detectors in parallel across zone 8 (terminals 26 and 27).
Remove the 2000 ohm EOL resistor if connected across the selected zone
terminals. You must connect the EOL resistor across the loop wires at the last
detector.

After an alarm, the first code + OFF turns off the siren and disarms the system;
the second code + OFF clears the memory of alarm and resets the glassbreak
detector.
