Silent Knight

Single-Ended Reflected Type Projected Beam Smoke Detector

Single-ended reflected type projected beam smoke detectors are designed to provide open area protection.

Single-Ended Reflected Type Projected Beam Smoke Detector

Single-ended reflected type projected beam smoke detectors are addressable beam smoke detectors for use with Silent Knight IntelliKnight Series fire alarm control panels (FACPs). The SK-Beam-T also includes an integrated sensitivity test feature. Installation of the single-ended reflective design is much easier than dual ended projected beam detectors. Alignment is quickly accomplished using an optical sight and a 2-digit signal strength meter incorporated into the single-ended reflected type projected beam smoke detectors. Listed for operation from -22º to 131º F (-30º to 55º C), the smoke detectors can be used in applications to provide early warning in environments where temperature extremes exceed the capability of other types of smoke detectors. Single-ended reflected type projected beam smoke detectors consist of transmitter/receiver unit and one reflector. When smoke enters the area between the unit and the reflector, it causes a reduction in the signal. When the smoke level reaches the predetermined threshold, the detectors generate an alarm signal. These beam smoke detectors have four sensitivity selections along with two acclimate settings. When either of the two acclimate settings are selected, the detector will automatically adjust its sensitivity using advanced software algorithms to select the optimum sensitivity for the specific environment.
