Series 65 Duct Smoke Detector

Product code: 53546-021APO

53546-021APO - Series 65 Duct Smoke Detector
The Conventional Duct Smoke Detector provides early detection of smoke in the air moving through heating and ventilation (HVAC) ducts in commercial and industrial premises. Its purpose is to prevent the re-circulation of smoke from an area on fire to areas unaffected by the fire when used with a Series 65 or Orbis detector. It provides a volt-free changeover relay rated at 30V, 1A.

Brand Information

Series 65 incorporates well-proven sensing technologies, including an Integrated Circuit based on that used in XP95 analogue addressable detectors. The Series 65 range has a wide operating voltage of 9–33V and consists of ionisation, integrating ionisation and optical smoke detectors, four grades of heat detector and a range of bases.

Brand Features

Wide-operating voltage of 9–33 V DC Wide-operating and storage temperature of -20°C to +60°C Can be used on security systems Electrically and mechanically compatible with Series 60 Proven detection performance

Electrical Description

The duct smoke detector is supplied as a housing with a base fitted for either a conventional detector or an analogue addressable detector. The housing has provision for electrical connections depending on the type of detector fitted. For technical data on the detector head, please refer to the relevant product guide or PIN sheet.

Operation

The duct smoke detector is fitted to the side, the top or the bottom of the ventilation duct and has two tubes which extend into the air duct through holes in the duct wall. The perforated sampling tube which spans the duct is placed in the airflow upstream of the exhaust tube which causes a pressure differential in the duct detector. Air is sucked up the sampling tube, across the detector and exhausted back into the air duct. The duct smoke detector is designed to operate in ducts with a width of between 300mm and 3000mm. A sampling tube of 360mm, suitable for duct widths up to 540mm, is supplied as standard. Longer sampling tubes for wider ducts may be ordered separately: 150—750mm Part no 53541-170 750—1500mm Part no 53541-171 1500—3000mm Part no 53541-172 The tubes should be long enough to reach from one side of the duct to the other and it may be necessary to use a tube that is too long and cut it to slightly more than the duct width. Since the tube needs to be supported on both sides a hole should be cut in the opposite wall of the air duct to allow the tube to protrude slightly. The tube must be closed with the small red bung provided. The exhaust tube does not need to extend across the duct and is therefore supplied at a fixed length.
