About the 4WITAR-B

A 4-wire photoelectric smoke detector with an isolated 135°F thermal sensor, built-in sounder, and Form C relay. Drift compensation and smoothing algorithms help reduce nuisance alarms caused by factors such as dust accumulation and RF interference.

Red and green LEDs indicate operating status, including power-up, standby, alarm, maintenance, and freeze trouble. The sounder produces an 85 dB temporal tone during an alarm. Sensitivity can be checked in seconds with a compatible sensitivity reader.

Features a plug-in design with base included, in-line terminals, and a Stop-Drop ’N Lock attachment.
