2. If an

EOL resistor

is presently connected across zone 1 terminals, remove it. The EOL

resistor must be connected across the loop wires at the last detector

In UL installations, only zone 1 may be used as a fire zone. In addition, an Ademco Model

610–7 must be used as the end-of-line resistor at the last detector.

The alarm current provided by zone 1 will support only one smoke detector in the alarmed state.

Wiring 4-Wire Smoke/Combustion Detectors on Zones 2-7

4-wire smoke detectors may not be used in UL installations.

The system will support as many 4-wire detectors as can be powered from Auxiliary Power

on the control on zones 2–7. Refer to the detector’s instructions for complete details regarding

its proper installation and operation.

1. Connect 12-volt power for the detectors from Auxiliary Power terminals 4 and 5 (which

will interrupt power for fire alarm reset). Observe proper polarity when connecting

detectors.

2. Connect detectors (including heat detectors, if used) across terminals of the zone selected.

All detectors must be wired in parallel.
