Bosch D7050DH Addressable Photoelectric Duct Smoke Detector Head None

The D7050DH is designed for use with the D343 Duct Smoke Detector Housing. The detector is a UL Listed, duct photoelectric smoke detector designed for use with commercial fire protective signaling systems and household fire warning systems (see NFPA 72, the National Fire Alarm Code). It is compatible with the FPD-7024 and D7024 Addressable Fire Alarm Control Panels (FACPs). It detects large smoke particles in air ducts by scattering light from a pulsed infrared source operating with a gated, high-speed, photodiode infrared sensor. The symmetry of the optical chamber allows 360° uniform smoke entry, but minimizes external light entry.
