Figure 6-4. Wiring Latching Glassbreak Detectors to Zone 8

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:

Standby Voltage: 5VDC–13.8VDC

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: 2mA–10mA

Reset Time: Less than 6 seconds

The IEI 735L Series detectors have been tested and found to be compatible with these

ratings. You can use up to 50 IEI 735L Detectors 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 glass break detectors on zone 8. Other

contacts may prevent proper glass break detector operation.

You can use detectors which exceed 1.1k ohms in alarm, provided they maintain a voltage

drop of less than 3.8 volts in alarm.

Checkout Procedure for Hardwired Zones

After installation of all hardwired zones is complete, each partition of the security system

should be checked as follows:

Make certain that all devices and sensors connected to the hardwired zones are not in a

faulted state. Doors and windows with contacts should be closed, PIRs should be covered

(use a cloth to mask them temporarily, if necessary).

With all hardwired zones intact, the alpha keypads connected to the system should

display:

DISARMED

READY TO ARM.
