Wiring 2-Wire Latching Glassbreak Detectors To Zone 8; Compatible Glassbreak Detectors - ADEMCO VISTA-32FB Installation And Setup Manual

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 Section 14:
External Sounders for information on AB12 bell wiring.

Wiring 2-Wire Latching Glassbreak Detectors to Zone 8

Use zone 8 for connection of compatible 2-wire latching-type glassbreak detectors. Wire as
follows:
1. Connect all detectors in parallel across zone 8 (terminals 26 and 27). See Figure 6-3.
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.
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.

Compatible Glassbreak Detectors

Use detectors that meet the following ratings:
The IEI 735L Series detectors have been tested and found to be compatible with these
ratings. Up to 50 IEI 735L detectors may be connected in parallel.
•
The alarm current provided by zone 8 will support only one glassbreak detector in the alarmed
state.
•
Do not use other N.O. or N.C. contacts when using glassbreak detectors on zone 8. Other
contacts may prevent proper glassbreak detector operation.
