AD2-P Siemens Duct Smoke Detector

Models AD2-P, AD2-PR, and AD2-XHR (AD2 Series) from Siemens Industry, Inc., are air duct monitoring housings containing sampling tubes.

Replacement: FDBZ492 Siemens

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.

The AD2 Series duct smoke detectors provide early detection of smoke and products of combustion present in air moving through an HVAC duct supply, return, or both. These devices are designed to prevent the recirculation of smoke in areas by the air handling system’s fans and blowers. Complete systems may be shut down in the event of smoke detection.
