INTRODUCTION
TECHNICAL DATA
ASSEMBLY
P/N A6V10330327_a_en
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.

Summary of Contents for Siemens FDBZ492-PR
- Page 1 Model FDBZ492-PR Global Air Duct Monitoring Housing 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.
- Page 2 OPERATION When the Model FDBZ492-PR is 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.
- Page 3 Detector LED The FDBZ492-PR contains an LED indicator (located on the smoke detector) capable of flashing either one of three distinct colors: green, yellow, or red. During each flash interval, the microprocessor based detector checks the following: • for smoke in its sensing chamber •...
- Page 4 The pressure differential between the input sampling (high pressure) tube and outlet (low pressure) tube for the FDBZ492-PR smoke duct detector should be greater than 0.01 inches of water and less than 1.2 inches of water. Identify a code compliant location (supply or return side, or both) for the installation of the duct unit that will permit easy access for viewing and serviceability.
