System Sensor’s intelligent, single-ended, reflected-type Beam200 Smoke Detectors protect open areas with high ceilings where installing and maintaining other methods of smoke detection are difficult. Alignment via an optical sight and a two-digit signal strength meter makes installation much easier than dual-ended projected beam detectors. Listed for operation from –22 deg. F to 131 deg. F, the unit is designed for open-area applications to provide early warning in environments where temperature extremes exceed the capability of other types of smoke detection. It provides 16- to 328-foot coverage and consists of a transmitter/receiver unit and a reflector. When smoke enters the area between the unit and the reflector it reduces the signal and, when the smoke level reaches the threshold, an alarm is activated. The detector has four standard sensitivity selections in addition to two Acclimate settings. System Sensor
