Interlogix GE449CRT Photoelectric Smoke Detector with Relay, 4-Wire

Item Description

The 449 Series low-profile, self-diagnostic, four-wire smoke detectors work on the light scattering principle. A pulsed infrared light-emitting diode serves as the light source, and a high-speed photo-diode as the sensing element. This design has superior protection against false alarms caused by dust, insects, RF, and ambient light.These smoke detectors are especially suited for residential occupancies, including hotels, motels, and dormitories, as well as other commercial and industrial fire-system applications. This series is designed for two-wire and four-wire connection to 6-24 VDC fire alarm control panels, UL Listed for commercial or household fire protection. The 449 Series is easily cleaned by replacing the proprietary field-replaceable optical chamber. All models are designed to reduce false alarms from dust, insects, RFI and external light.An integral combination rate-of-rise and fixed 135°F (57°C), 50-foot rated, heat sensor is available with all "T" model detectors.
