2151 Photoelectric Smoke Detector

The System Sensor low profile photo electronic smoke detector is specifically designed to meet the performance requirements of the fire detection/alarm systems.

The System Sensor low profile photo electronic smoke detector is specifically designed to meet the performance requirements of the fire detection/alarm systems. The detector uses a state-of-the-art optical sensing chamber and is designed so that if the LED fails, it will not cause an alarm. The detector is designed to provide open area detection, and when installed in a two-wire base, is compatible with the Gamewell-FCI fire alarm control panels. The detector’s operation and sensitivity can be tested in place. The 2151 detector is designed with plug-in construction and plugs into the same base as the 1151 ionization smoke detector, making both models interchangeable. Bases are available for the following types of operation.
