Bosch Addressable Photoelectric Smoke Detector Head

The D7050 MUX smoke head and D7050TH MUX smoke head w/ fixed heat (135°F) are UL Listed, open-area photoelectric detectors. They are designed for use with commercial fire protective signaling systems and household fire warning systems (see NFPA 72). They are compatible with the: FPD-7024 Family fire alarm control panels (addressable versions), D7024 Family fire alarm control panels (addressable versions), DS7400Xi Series Addressable Control Panels, G Series control panels (D9412G, D8412G, D7212G or later).

The symmetry of the optical chambers allows 360 degree uniform smoke entry, but minimizes external light entry. In the chamber, large smoke particles scatter infrared light from a pulsed source operating with a gated, high-speed, photodiode sensor. The D7050TH has an added fixed-temperature sensor. Use in confined areas, such as furnace rooms and closets. Areas where a fire increases air temperature slowly but substantially before the fire breaks confinement.
