Compatible Glass Break Detectors
Use detectors which are compatible with the following ratings:
Standby Voltage:.......... 5VDC-Ð13.8VDC
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: .............. 2 mA -Ð10 mA
Reset Time:.................. Less than 6 seconds
The IEI 735L series detectors have been tested and found to be compatible with these
ratings. Up to 50 IEI 735L detectors, connected in parallel, may be used (the alarm
current provided by this zone is sufficient to support operation of only one detector in
alarmed state). Follow the manufacturer's recommendations on proper installation.
Detectors which exceed 1.1k ohms in alarm, but maintain a voltage drop in alarm of less
than 3.8 volts can also be used.
Zones 2-8 Advisories
If latching type devices are installed on both zones 1 & 8, and these zones are assigned
to different partitions, there is a possibility that, if both devices go into alarm at the same
time, the resetting of one device could cause the loss of alarm memory in the other
device.
Use of N.O. or N.C. contacts on the same zone may prevent proper glass break detector
operation.
UL NOTE: 4-wire smoke detectors cannot be used in UL installations.
Hard-wired Zone 9
Applications This zone is unsupervised and is suitable for monitoring fast-
acting glass break sensors or vibration sensors when pro-
grammed for fast response.
Response Type Any type except fire (09), and types 20Ð22 (these are used
only for 5800 series wireless transmitters).
Response Time Fast (10 msec) or slow (350 msec) response selected in field
*14.
Max. Zone Resistance 300 ohms
Unsupervised Usage ¥ Only closed circuit devices can be used.
¥ Connect these devices in series with one another between
terminals 22 & 23.
Zone 9 Advisories
Avoid using mechanical magnetic or relay type contacts in this zone when programmed
for fast response.
UL NOTE: The interconnecting wires from zone 9 shall be no longer than 3 feet, with no
intervening walls or barriers for UL installations.
