Edwards Signaling EC-50R Reflective Beam Smoke Detector

The EDWARDS-SIGNALING-EC-50R is a beam smoke detector that comprises a transmitter and receiver in a single enclosure and is usually installed between 19 inches and 24 inches below the ceiling. The unit is equipped with a test filter and one reflector.

The EC-50R emits an invisible infrared light beam that is reflected via a prism mounted directly opposite and with a clear line of sight. The reflected infrared light is detected by the receiver and analyzed. Smoke in the beam path will reduce the received infrared light proportionally to the density of the smoke. The detector analyzes this attenuation or obscuration of light and acts accordingly.

The EC-50R is ideal for large open areas such as warehouses, hotel atriums, industrial plants and school gymnasiums. The detector is often mounted within 30 feet (9.14 m) of a potential fire source.
