Photoelectric Detector


System Sensor 2151BPI detectors are designed to meet the performance criteria designated by fire detection standards throughout the world. The 2151BPI photo-electronic smoke detector contains a unique optical sensing chamber designed to sense smoke particles produced by a wide range of combustion sources. A custom integrated circuit incorporates signal processing to reduce false alarms. Stability in high air velocities is a prime benefit in many applications (up to 15.2m/s)
The sensing chamber is sealed against back pressure air flow and the chamber is further protected by a fine mesh screen to limit the ingress of contaminants such as dust and insects. This screen can be readily cleaned and replaced. Additional key features include a variety of mounting bases, and a full line of accessories.
