The System Sensor 4WTAR-B Photoelectric i3 Series Smoke Detector is a reliable conventional fire detection solution designed for fast installation, intelligent performance, and simplified maintenance.
Featuring a built in sounder, thermal sensor, and Form C relay, this 4 wire smoke detector provides enhanced life safety protection for commercial and residential applications.
Part of the trusted i3 Series, the 4WTAR-B uses advanced drift compensation and smoothing algorithms to reduce nuisance alarms caused by dust, RF interference, and environmental changes. These intelligent features help maintain long term detection accuracy while minimizing unnecessary service calls.
The integrated 85 dB sounder provides immediate local notification during alarm conditions, while the built in Form C relay allows easy integration with auxiliary devices and control systems. The addition of a thermal sensor enhances detection capabilities by responding to both smoke and heat conditions for improved safety.
The System Sensor 4WTAR-B also includes red and green LED indicators for clear visual status during power up, standby, alarm, maintenance, and freeze trouble conditions. When used with compatible modules such as the 2W-MOD2 or RRS-MOD, the detector supports remote maintenance signaling and synchronized sounder activation across multiple devices.
Ideal for offices, schools, healthcare facilities, retail spaces, and commercial buildings, the 4WTAR-B delivers dependable performance with easy installation and maintenance.
