Wiring 2-Wire Latching Glass Break Detectors On Zone 8
Use zone 8 for connection of compatible 2-wire latching-type glass break
detectors.
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.
¥ Connect all detectors in parallel across zone 8 (terminals 19 and 20).
You must connect the EOL resistor across the loop wires at the last detector.
Remove 2000 ohm EOL resistor if connected across the selected zone
terminals.
Compatible Glass Break Detectors
Use detectors that meet the following ratings:
Standby Voltage:
Standby Resistance: Greater than 20k ohms (equivalent resistance of all
Alarm Resistance:
Alarm Current:
Reset Time:
The IEI 735L series detectors have been tested and found to be compatible
with these ratings. You can use up to fifty IEI 735L detectors, connected in
parallel.
You should note that only one detector in the alarmed state can be
supported by the alarm current provided by zone 8.
You can use detectors which exceed 1.1k ohms in alarm, provided they
maintain a voltage drop in alarm of less than 3.8 volts.
Do not use other N.O. or N.C. contacts when using glass break detectors on
zone 8. Other contacts may prevent proper glass break detector operation.
