System Sensor’s single-ended, reflected-type Beam Smoke Detectors protect open areas with high ceilings and feature a four-wire design. Alignment is accomplished via an optical sight and a built-in, two-digit signal strength meter. Available with an integral sensitivity test module, these detectors provide 16-foot to 328-foot protection coverage in an operating temperature range from –22 deg. F to 131 deg. F to give early warning in environments where temperatures reach extremes. Two Acclimate settings automatically adjust sensitivity using advanced software algorithms to select the optimum level for a specific environment. The detectors are available as conventional or intelligent models and can be equipped with an integral sensitivity test feature that consists of a test filter attached to a servomotor inside the detector optics.
