System Sensor 2151 Low Profile, Plug-in Photoelectric Smoke Detector

Low profile, plug-in photoelectric smoke detector

---

The System Sensor 2151 is a low profile, plug-in photoelectric smoke detector.

100 Series Plug-in Smoke Detectors offer superb performance and reliability in a profile which is just 2" (5.1 cm) deep.

Model 2151 (photoelectric sensor) and model 2151T (photoelectric sensor with thermal) can be used with a variety of adapter bases in several wiring configurations and voltages. 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 is designed to meet the performance criteria designated by UL. Its sensing chambers are sealed against back pressure air flow, dirt and insects. This chamber is protected by a fine mesh screen, which can be cleaned or replaced.

Additional key features include a variety of mounting bases 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. Model 2151 photoelectric detector’s unique optical sensing chamber is engineered to sense smoke by a wide range of combustion sources. Dual electronic thermostats add 135°F fixed temperature thermal sensing on model 2151T.
