Kit includes a D343 Duct Detector Housing, a D7050HD Photoelectric Duct Smoke Detector Head, and a D344-1.5 Sampling Tube.
The D343 Series Duct Smoke Detector Housings mount on the ducts of heating, ventilation, and air conditioning (HVAC) systems to monitor the presence of smoke in the conditioned air. The D343 Housings operate on the MUX bus of the D7024 Addressable Fire Alarm Control Panel (ROM version 2.0 or higher). An external 24 VDC or VAC supply is also required.
The efficient housing design samples the air passing through a duct and detects potentially hazardous conditions. When smoke is detected, the detector sends an alarm signal to the control panel or HVAC control equipment that initiates the necessary action to control air handling systems.
The D7050DH 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 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.
