Wiring 2-Wire Smoke Detector; Figure 4. 4-Wire Smoke Detector Connections - ADEMCO 5110XM Installation Instructions Manual

Remove 2000 ohm EOL resistor if connected across the zone terminals, and
connect it across the loop wires at the last detector.
3. To supervise power, you MUST use a UL listed End-Of-Line Power
Supervision Relay (i.e. System Sensor No. A77-716B).

Wiring 2-Wire Smoke Detectors To Zone 5
1. Connect up to 16 of the 2-wire smoke detectors listed below across zone 5
terminals 15 (+) and 16 (–). Observe proper polarity when connecting the
detectors.
2. Connect the EOL resistor at the last detector.
3. See "Programming Hard-Wired Zones" later in this section for a detailed
programming procedure.
Due to the alarm current available on zone 5, only one smoke detector at a
time can be supported in the alarmed state.
