FDBZ492-R Siemens Duct Housing – 2 Wire With Relay For Conventional Systems

Models FDBZ492, FDBZ492-R, and FDBZ492-HR from Siemens Industry, Inc., are air duct monitoring housings containing sampling tubes. When used with a compatible smoke detector, smoke and combustion products are detected for the shutdown of the duct system and/or operation of supplementary equipment as provided by the system control panel.

When the Models FDBZ492, FDBZ492-R, and FDBZ492-HR are operating, a sample of air is drawn from the duct and passed through the sampling chamber by means of the input sampling tube. The air sample passes through the smoke detector mounted in the duct housing and is exhausted back into the duct through the outlet tube.

This detector is equipped with cover removal switches (SW1, SW2) that instantly provides a trouble condition upon removal of the clear cover. For all testing and inspection with the cover removed, the cover removal switches (designated as SW1, SW2 on PCB) must be manually depressed to simulate normal operation.
