The FDBZ492 is a Siemens duct fire detection base that mounts in HVAC ductwork and houses an addressable smoke detector head. It samples air moving through supply and return air ducts, providing early detection of smoke that could be distributed throughout a building via the air-handling system. The base integrates with Siemens Cerberus PRO and FireFinder XLS fire alarm systems via the 2-wire signal line circuit.
