Global Air Duct Monitoring Housing
Installation Instructions
Model FDBZ492-PR
INTRODUCTION
Model FDBZ492-PR from Siemens Industry, Inc., is a RoHS
compliant air duct monitoring housing containing sampling
tubes. When used with a Siemens conventional smoke detector,
smoke and combustion products are detected for shutdown of
the duct system and/or operation of supplementary equipment
as provided by the system control panel. The duct unit supports
two sets of Form C alarm contacts, one Form A alarm contact
and one Form C trouble contact. The trouble contact supervises
the presence of the input power, removal of the detector cover
and the removal of the smoke detector head.
