Description

The System Sensor 2351BR is an intelligent, addressable photoelectric smoke detector designed for open area and duct smoke detection applications. It combines a photoelectronic sensing chamber with addressable-analog communications and supports both Advanced Protocol and CLIP (Classic Loop Interface Protocol) modes.

The 2351BR features remote test capability when used in duct applications with compatible DNR(W) housings, eliminating the need for a test coil. Rotary decimal address switches allow precise point identification, while dual panel-controlled LEDs provide visible status indication. The detector transmits an analog representation of smoke density to a listed-compatible control panel for monitoring and alarm processing.
