ADDRESSABLE PHOTOELECTRIC SMOKE AND HEAT DETECTOR HEAD
D7050TH Addressable Photoelectric Smoke and Heat Detector Head The D7050TH, in addition to an optical smoke chamber, has an added 135Â°F (57Â°C) fixedtemperature sensor that expands its application to confined areas where a fire increases air temperature slowly and where there is a substantial increase in air temperature before the fire breaks confinement.
The D7050 Photoelectric Smoke and Smoke Heat Detector Heads are UL Listed, open-area photoelectric smoke detectors designed for use with commercial fire protective signaling systems and household fire warning systems (see NFPA 72, the National Fire Alarm Code). They are compatible with the FPD+7024 or D7024 Addressable Fire Alarm Control Panels (FACPs), the DS7400Xi Control Panel, and the G Series Control Panels.
They detect large smoke particles by scattering light from a pulsed infrared source operating with a gated, high-speed, photodiode infrared sensor. The symmetry of the optical chamber allows 360Â° uniform smoke entry, but minimizes external light entry. Use both of these smoke detectors for detection circuits installed in areas where personnel are present. The D7050TH has an added fixed-temperature sensor. This expands(more...)
