 Connect closed circuit devices in series in the high (+) side the loop. The 2,000 ohm EOL resistor must be connected
in series with the devices, following the last device. See the Summary of Connections diagram.
 Connect open circuit devices in parallel across the loop. The 2,000 ohm EOL resistor must be connected across the
loop wires at the last device.
If the EOLR is not at the end of the loop, the zone will not be properly supervised, and the system may not respond
to an open circuit on the zone.
Wiring 4-Wire Smoke Detectors on Zones 1-5
The system will support as many 4-wire detectors as can be powered from Auxiliary Relay Power on the control. Refer to
the detector’s instructions for complete details regarding its proper installation and operation.
Compatible 4-Wire Smoke Detectors
Use any UL Listed 4-wire smoke detector that is rated for 12VDC operation and that has alarm reset time not exceeding
6 seconds. Some compatible 4-wire smoke detectors are listed below.

 Power to 4-wire smoke detectors must be supervised with an EOL device relay module connected as shown in
Figure 2-8).
 A combination of heat detectors and smoke detectors is not permitted on a zone programmed for fire verification.
 Fire installations require the use of a synchronization module to synchronize the sounders and strobes on the
system.
Connect 12 volt power for the detectors from Auxiliary Relay Power terminals 7 (+) and 18 (-). Be sure to program the
Aux Power Relay for the smoke detector reset function in program field 34. Observe proper polarity when connecting
detectors.
Connect detectors (including heat detectors, if used) across zone terminals. All detectors must be wired in parallel with
the 2,000 ohm resistor wired in parallel at the last device in the loop.
Remove 2000 ohm EOL resistor if connected across the zone terminals, and connect it across the loop wires at the
last detector.
To supervise power, you MUST use a UL listed End-Of-Line Power Supervision Relay (i.e. System Sensor No. ELOR-1).
