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

PR is operating a sample of air is from the duct and passed through the sampling chamber by of the input sampling tube The air sample passes through smoke detector mounted in the duct housing and is exhausted into the duct through the outlet tube FDBZ492 PR supports two sets of Form C alarm one Form A alarm contact and one Form C trouble The trouble contact supervises the presence of the power removal of the detector cover and the removal the smoke detector head FDBZ492 PR contains a green power on LED red alarm and yellow trouble LED which are visible through the cover trouble LED is activated when either the housing cover smoke detector is removed from the unit When the trouble LED is activated the power LED turns off reset test switch is located on the housing cover and is to reset the unit after an alarm and the smoke is cleared When not in alarm the reset test can be used to test that the unit will operate when an alarm condition exists trouble contacts will not operate in the event of a smoke alarm FDBZ492 PR duct detector will operate from various input sources namely 24VAC 24VDC 115VAC and 230VAC Industry Inc Technologies Division A6V10330327 a en LED FDBZ492 PR contains an LED indicator located on the detector capable of flashing either one of three distinct green yellow or red During each flash interval the based detector checks the following smoke in its sensing chamber its critical smoke sensing electronics are operating on the results of these checks the LED indicator flashes follows guideline contains general information on duct smoke installation but does not preclude the NFPA docu listed Siemens Industry Inc assumes no responsibility improperly installed duct detectors To determine the correct position for an FDBZ492 PR duct smoke detector the factors must be considered A uniform non turbulent laminar airflow between 100 ft to 5,000 ft min must be present in the HVAC duct To duct velocities examine the engineering that define the expected velocities or use an model 6000AP velocity meter or equivalent minimize the impact of air turbulence and stratification performance a duct smoke detector should be located far as possible downstream from any obstruction i e plates elbows dampers etc In all situations THE AIR DUCT HOUSING on Duct System Industry Inc Technologies Division A6V10330327 a en of velocity and pressure differential within is required pressure differential between the input sampling high tube and outlet low pressure tube for the smoke duct detector should be greater than inches of water and less than 1.2 inches of water a code compliant location supply or return side or for the installation of the duct unit that will permit access for viewing and serviceability When installing on the return side install duct units prior to air being exhausted from the building or diluted with air When installing duct smoke units downstream of filters occurring in the filters will be detected but if the filters blocked insufficient air flow through the duct unit prevent the correct operation of the duct detector Duct installed in the supply air side may monitor upstream and or filters DUCT
