Using 2-Wire Latching Glassbreaks on Zone 8
Zone 8 can support 2-wire glassbreak detectors. The
zone provides enough standby current to power up to 50
2-wire glassbreak detectors meeting the requirements
listed below.
Compatible Glassbreak Detectors
Use detectors that meet the following ratings:
Standby
Voltage:
5VDC13.8VDC
Standby
Resistance:
Greater than 20k ohms (equivalent
resistance of all detectors in parallel)
Alarm
Resistance:
Less than 1.1k ohms (see note below)
Alarm
Current:
2mA10mA
Reset Time:
Less than 6 seconds
NOTES:
You can use detectors that exceed 1.1k ohms in
alarm, provided they maintain a voltage drop of
less than 3.8 volts in alarm.
The ASC-SS1 detector has been tested and found to
be compatible with these ratings.

Figure 3-15: Wiring Latching Glassbreaks to Zone 8
The alarm current provided by zone 8
supports 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.
To wire 2-wire latching glassbreak detectors to zone 8,
perform the following steps:
Step Action
1 Select compatible 2-wire glassbreak
detectors that meet the requirements stated
previously.
2 Connect detectors across zone 8 (terminals
21 and 22). See Figure 3-15.
3 Connect the EOL resistor at the last detector
in the loop across the zone’s terminals. You
must connect the EOL resistor across
the loop wires at the last detector.
