Description
The Model 30-3003D uses air sampling tubes to provide a cross sectional sampling of air moving through the duct. Inlet sampling tubes are available in four lengths: one foot, three feet, six feet, and ten feet.
The length of the inlet sampling tube is determined by the width of the duct to be monitored. The inlet duct, therefore, specify the shortest sampling tube that is at least the width of the duct to be protected. It can then be cut to the exact length at the job site.
Outlet tubes are one common length. Both inlet and outlet tubes are furnished with each detector.
The Harrington Model 30-3003D Explosion-Proof Air Duct Smoke Detector is designed to detect the presence of smoke for the primary purpose of controlling blowers and dampers in air conditioning and ventilation systems and is intended for use in hazardous industrial and commercial locations. The unit mounts directly to heating, ventilating, and air conditioning ducts and utilizes a cross sectional sampling tube arrangement rather than a substitute for open area detection.
The explosion-proof air duct smoke detector is intended to be connected to a control unit and function as part of a fire protection system. The 30-3003D is designed for use with a 4-wire system fire alarm control panel (2 wires for detector power and 2 wires for detector output).
The detector operates on the forward light scattering principle, a technology that is based on more than 30 years of experience in advanced photoelectric detection systems.
