Potter Installation Manual PAD100-DUCT Analog Addressable Duct Detector

Installation Manual PAD100 DUCT Analog Addressable Duct Detector TO THE INSTALLER manual provides an overview and the installation instructions for the PAD100 DUCT module This module is only compatible addressable fire systems that utilize the PAD Addressable Protocol terminals are power limited and should be wired in accordance with the requirements of NFPA 70 NEC and NFPA 72 National Alarm Code Failure to follow the wiring diagrams in the following pages will cause the system to not operate as intended For information refer to the control panel installation instructions module shall only be installed with listed control panels Refer to the control panel installation manual for proper system Description PAD100 DUCT duct smoke detector provides early detection of smoke and products of combustion present in the air moving HVAC ducts in commercial industrial and residential applications The PAD100 DUCT is designed and built to meet all requirements as well as the NFPA regulations regarding duct smoke detectors sampling is accomplished by two tubes which protrude into the duct An exhaust tube of one standard length 7 is supplied the installation kit with the smoke duct unit Once the duct width has been determined the air intake sampling tubes must be Sampling tubes are supplied in three standard lengths 2.5 ft 5 ft and 10 ft and cut to size to fit the duct Mounting duct smoke unit is accomplished by the use of a template and 2 sheet metal screws which are provided Mounting can be without the removal of the clear cover which is secured by 4 capture screws Setting the Address PAD protocol detectors and modules require an address prior to connection to the panel SLC loop Each PAD device i e detector and or module is set by changing the dip switches located on the device PAD device addresses are of a seven 7 position dip switch used to program each device with an address ranging from 1 1 PAD Device Dip Switch Addresses Table Addresses 1

MANUAL PAD100 DUCT ANALOG ADDRESSABLE DUCT DETECTORfirealarmresources com Mechanical Installation Instructions PREREQUISITES This guideline contains general information on the PAD100 DUCT duct smoke detector installation does not preclude the NFPA and or ICC documents listed Potter Electric Signal Company assumes no responsibility for installed duct detectors To determine the correct installation position for a PAD100 DUCT duct smoke detector the factors must be considered A uniform non turbulent laminar airflow between 100 ft min to 4,000 ft min must be present in the HVAC duct To determine velocities examine the engineering specifications that define the expected velocities or use an Alnor model 6000AP meter or equivalent To minimize the impact of air turbulence and stratification on performance a duct smoke detector should be located as far possible downstream from any obstruction i e deflector plates elbows dampers etc In all situations confirmation of and pressure differential within specifications is required pressure differential between the input sampling high pressure tube and exhaust low pressure tube for the PAD100 duct smoke 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 viewing and serviceability air When installing on the return side install duct units prior to the air being exhausted from the building or diluted with outside When installing duct smoke units downstream of filters fires occurring in the filters will be detected but if the filters become insufficient air flow through the duct unit will prevent the correct operation of the duct detector Duct units installed in supply air side may monitor upstream equipment and or filters Where possible install duct detectors upstream of air humidifiers and downstream of dehumidifiers To prevent false alarms the duct detector should not be mounted in areas of extreme high or low temperatures in areas high humidity exists or in areas where the duct may contain gases or excessive dust TUBE ASSEMBLY The PAD100 DUCT duct smoke detectors employ a specially notched sampling tube which may ordered separately in one of four 4 standard lengths For duct widths of 6 TO 1.0 For duct widths of 1.0 TO 3.0 For duct widths of 3.0 TO 5.0 For duct widths of 5.0 TO 10.0 sampling tubes are steel tubes with air intake holes located the entire length of the tube These tubes must be cut to and should span the entire width of the duct Sampling tubes over 3.0 must be supported on the opposite side of the duct ensure the correct operation of the sensing tube the red end cap red stopper in installation kit must be inserted in the end the air intake sampling tube For custom duct widths always use the next longest standard size and cut down to the exact TUBE INSTALLATION The PAD100 DUCT duct smoke detector provides a unique patented mechanism for and or removal of the sampling and exhaust tubes from either the front or rear of the detector housing Once the airflow has been determined insert the inlet and exhaust tubes into the duct smoke detector If the cover is in place the tubes be inserted into the back of the detector via the key slots provided Simpl
