2. Connect detectors (including heat detectors, if used) across terminals of the zone selected.
See Figure 6-2. All detectors must be wired in parallel. Remove the 2000-ohm EOL
resistor if connected across the selected zone terminals. The EOL resistor must be
connected across the loop wires at the last detector.

Compatible 4-Wire Smoke Detectors

Use any UL Listed 4-wire smoke detector that is rated for 10-14VDC operation and has
alarm reset time not exceeding 6 seconds. Some compatible 4-wire smoke detectors are listed
below.

Fire Alarm Verification for Smoke Detectors

This feature applies to any hardwired or polling loop fire zone set to zone type 16. For 4-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-32FB Cabinet Door Tamper Switch and
for the ADEMCO AB12 Grade A Burglary Bell Box Tamper Switches and Tamper Liner.
Assign zone 6 to a burglary partition. Program it for day trouble/night alarm (zone type 5)
when only one burglary partition is used. Program it for 24-hr. audible alarm (zone type 7)
