narizes zones 2-8 characteristics.

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

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.
