Description

Details

The 2W-MOD2 allows a control panel to receive a “need for maintenance” signal from two–wire i3 series smoke detectors, model numbers 2W–B, 2WT–B, 2WTA–B, and 2WTR–B.
The module uses a form C zone relay to initiate “out of sensitivity” and “freeze trouble”, a form A zone alarm relay and a second form A zone relay to indicate loop fault. An EZ Walk Test puts all detectors on the loop into a Walk Test mode for easy verification of detector loop wiring.
Three LED’s on the module provide a local visual indication of the module status(es).
The maintenance module allows two-wire smoke detectors to be used on any electrically compatible four-wire control panel.
