Can be used for EOLR supervised or closed circuit
unsupervised devices. Can also support 4-wire smoke
detectors. Zone 8 can support Iatchmg glass break
Zones 1-7:300 ohms, excluding EOLR
Zone 8: 100 ohms, excluding EOLR
EOLR disabled in field *41 (enter 1).
Only closed circuit devices can be used.
EOLR enabled in field “41 (enter O).
Supports both open circuit and closed circuit devices.
Connect open circuit devices in parallel across the
loop. The 2,000 ohm EOLR must be connected
across the loop wires et the last device.
s Connect closed circuit devices in series with the loop.
Supports up to 50 2-wire latching type glass break
detectors.
Configure as EOLR zone
c Second CODE + OFF sequence momentarily
interrupts power to reset the glass break detectors.
See table below for compatible detectors.

Supports as many 4-wire smoke detectors as can be
powered
Assign zone response type 09 (fire).
The zones must be configured for EOLR supervision.
A normally-closed, momentary switch must be installed
in
series with the power to the detectors in order to
allow reset of the smoke detectors after an alarm.
The detectors must be wired in parallel, with the EOLR
at the last detector for full supervision.
To supervise power, a System Sensor No. A77-716
EOL Relay Module is reco-mmended.
Compatible Glass Break Detectors
Use detectors which are compatible with 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. 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.
