System Sensor 2151 Photoelectric Smoke Detector

System Sensor 2151

The (photoelectric sensor) and model 2151T (photoelectric sensor with thermal). Can b e used with a variety of adapter bases in several wiring configurations and voltages. The other features include low current draw, stable performance in high air velocities. Built-in tamper-resistant base design, remote LED option, removable cover, and built-in test switch.

The 100 series comes designed to meet the performance criteria designated by UL. The sensing chamber i s sealed against backpressure airflow. The chamber top i s covered by a one-piece mold screen which minimizes the entry of dirt and insects. This screen can b e removed for cleaning. The key features include a variety of mounting bases as and a full line of accessories.

All 100 Series photoelectric smoke detectors contain 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.

The System Sensor photoelectric detector’s unique optical sensing chamber i s engineered to sense smoke. By a wide range of combustion sources. Dual electronic thermistors add 135°F fixed temperature thermal sensing on model 2151T.
