SYSTEM SENSOR 4WTR-B

Product Overview

The System Sensor i3 4WTR-B is a 4-wire smoke detector with integrated sounder and relay, designed to deliver easy installation, intelligent functionality, and immediate visual feedback. Its plug-in design allows installers to pre-wire the included base and securely attach the detector using the Stop-Drop ’N Lock mechanism. The base supports a wide range of mounting options, including octagonal, single-gang, 4-square back boxes, or direct ceiling installation, while providing ample room for neat wiring.
