2WTR-B SYSTEM SENSOR

I3 PHOTO DETECTOR, PLUG-IN, 2-WIRE, 12/24 VDC, 135 °F THERMAL, FORM-C RELAY.a

Product Overview

The System Sensor 2WTR-B is a 2-wire i3 sounder and relay smoke detector designed around the i3 principles: installation ease, intelligence, and instant inspection. Its plug-in design with an installer-friendly base simplifies installation, allowing pre-wiring and accommodating a wide range of back box and direct mounting options. 

The 2WTR-B integrates a Form C relay, an isolated thermal sensor, and an 85 dB sounder, making it suitable for applications requiring both notification and auxiliary signaling. Intelligent features like drift compensation, smoothing algorithms, and remote maintenance signaling help reduce nuisance alarms and simplify ongoing system maintenance.
