Description

The System Sensor 2251B is a 200 Series intelligent low-profile plug-in photoelectric smoke detector designed for use on compatible addressable fire alarm systems. It provides analog communication with point ID capability, enabling each detector’s address to be set via rotary decade switches for precise device identification and selective maintenance.

The 2251B features a unique optical sensing chamber engineered to detect smoke from a wide range of combustion sources. Detector sensitivity can be programmed through the control panel software and is continuously monitored and reported to the panel. Dual LEDs provide 360° visibility for local status indication.

The detector plugs into a separate mounting base, allowing simplified installation, maintenance, and interchangeability with other 200 Series sensor types.
