Kidde Edwards Data Sheet K85001-0613 - Intelligent Duct Smoke Detector

Intelligent Duct Detector Kidde FX PDD Duct Smoke Detector is designed for easy and represents the perfect balance of practical design advanced technology FX PDD features a unique design that speeds installation and maintenance Removable dust filters conformally coated boards and optional water resistant gaskets keep con away from components ensuring years of trouble free When cleaning is required the assemblies come apart and snap back together in seconds duct smoke detector primary purpose is to provide early of an impending fire and shut down the HVAC unit in to prevent smoke from circulating throughout the building duct smoke detector is designed for use in duct applications temperatures can exceed standard detector capabilities Duct detectors have specific limitations Duct detec are not a substitute for an open area smoke detector Duct are not a substitute for early warning detection or a for a building regular fire detection system Smoke are not designed to detect toxic gases which can up to hazardous levels in some fires These devices will not without electrical power As fires frequently cause power Kidde suggests you discuss further safeguards with local fire protection specialist Features Less than 2 deep for easy installation and applications where is tight 32 to 120 0 to 50 operating range with 100 ft min to ft min air velocity rating assures reliability under harsh conditions Status LEDs remain visible through clear assembly cover Cover monitor switch for added security Standard sampling tube spacing for easy drop in migration other detectors Sampling tube can be installed with or without the cover in and can be rotated in 45 degree increments to ensure alignment with duct airflow 15.2 to 19.95 Vdc operation Magnet activated test

duct detection applica where early indication combustion is required the confined space ventilation ductwork primary purpose is to early warning of an fire and to pre smoke from circulating the building is typically used to detect smoke in the supply side of the HVAC but can provide supervision of the return side as well smoke relay detectors continually sample air flow in the HVAC duct and an alarm condition whenever smoke is detected An alarm activated when the quantity percent obscuration of combustion in that air sample exceeds the detector sensitivity setting Intelligence all FX Series intelligent devices the FX PDD detector fea rotary addressing and issues a dirty sensor warning when reaches its preset limit The dirty sensor warning indicates the is operating within its specified limits but is in need of serv When the detector ability to compensate for environmental has reached its limit the duct smoke detector signals a condition FX PDD also uses differential sensing to prevent gradual changes from triggering unwanted alarms A rapid in environmental conditions such as smoke from a fire the detector to signal an alarm state but dust and debris over time does not change alarm sensitivity FX PDD detector contains a microprocessor that performs self diagnostics and stores the results in nonvola memory Stored results include details such as hours of opera last maintenance date and number of alarms and troubles information can be retrieved and reviewed when desired Configuration detector assembly cover provides easy access to the smoke its wiring connections sample and exhaust tubes and the chamber itself enters the detector sensing chamber through a sampling ordered separately that extends into the duct and is directed into the ventilation system through an exhaust tube in The difference in air pressure between the two tubes pulls sampled air through the sensing chamber When a sufficient of smoke is detected in the sensing chamber the detector an alarm sampling tube may be installed from either the duct side of assembly or from inside the sensor compartment as preferred the installer The exhaust tube must be installed from the duct Sampling tubes may be rotated in 45 degree increments so air holes can be aligned to allow the unit to be mounted at any angle relative to the air flow installations where the duct smoke detector controls and indica are hidden from view a remote test station or an LED indicator be connected to the detector to provide these functions 2 of 4 Test Stations Labor saving Remote Test Reset stations provide testing from the convenience of a remote Tests can be performed quickly and safely without having to climb to the roof Magnetically and key operated one gang models are FX PDD detectors are also compatible R LED remote alarm LED velocity in the duct as low as 100 ft min maintains adequate flow into the sensor smoke chamber through air holes in the sampling tube and discharges through the exhaust tube Air tubes must be installed with the inlet holes facing the air Sampling tubes may be rotated in 45 degree increments that air holes can be aligned to allow the unit to be mounted in any angle relative to the airflow sensors are engineered to operate optimally under the environmental conditions frequently found in HVAC duc Nonetheless before installing the detector test the duct velocity temperature and humidity to verify that it is within the range of the detector Consult the FX PDD installation for details station specifications Test Reset Stations provide alarm test trouble indication reset capability from a remote location They include a one plate momentary SPST switch red alarm LED and termi block Magnetically operated models TRM or key operated TRK are
