●
●

●
Program Zone 1 as a Fire zone (type 09).
Program Field
●41 as a “O” (EOLR required).
Leave Red PCB jumper intact.
Supports up to eight (8) 2-wire smoke detectors.
Open circuit devices must be connected in parallel
across terminals 9 & 10. A
2000 ohm EOLR must be
connected across the furthest device.
Connect closed circuit devices in series with the loop.
Field 1*46 (AUX Output Enable) may be set to “3”
(zone 1 EOLR)
Second OFF sequence momentarily interrupts the
loop power to reset the smoke detectors.
See table below for compatible smoke detectors.

If the EOLR is not at the end of the loop, the zone is not properly supervised. The
system may not respond to an open circuit within the zone.
The alarm current provided by this zone is sufficient to support operation of only
one detector in the alarmed state.
UL NOTE: EOLRSare required for UL installations
The Following Table Summarizes Zones 2-8 Characteristics.
Applications
1Can be used for EOLR supervised or closed circuit
unsupervised devices. Can also support 4-wire smoke
detectors. Zone 8 can support latching glass break
detectors.
Zone Response Type Any.
Response Time Zones 1-7:350 msec; Zone 8: optional 10-15 msec
(as programed (field ●14)
Max. Zone Resistance s Zones 2, 3, 4, 5, 7, 8:300 ohms, excluding EOLR.
Zone 6:100
ohms.
Unsupewised Usage
. EOLR disabled in field
*41 (enter 1).
● Only closed circuit devices can be used.
EOLR Supervised
.
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
at the last device.
● Connect closed circuit devices in series with the loop.
Glass Break Devices
● Supports up to 50 2-wire latching type glass break
on Zone 6
detectors.
● Configure as EOLR zone.
● Second CODE + OFF sequence momentarily
interrupts power to reset the glass break detectors.
