ULC S530 Actuated Fire Detection FM 3230 CSFM File 7272 0067 0258 Restriction of Hazardous Substances Product Overview Photoelectric Smoke Detector Model FDO421 uses state of the art circuitry and surface mount maximum Model FDO421 incorporates an optical sensor using a light detection principle The device utilizes advanced software to analyze the signals and provides highly stable and accurate detection FDO421 also uses state of the art microprocessor circuitry with error detector self diagnostics and supervision programs detector is UL 268 7th edition listed incorporating advanced built in True Class X SLC operation use is optional greatly system reliability and circuit integrity while providing advanced fault finding unit fits into one 1 wall or ceiling footprint and only occupies one 1 on the signal line circuit SLC FDO421 is a plug in two wire addressable photoelectric smoke whose value is increased with built in ISOtechnology feature Model is Underwriters Laboratories Listed UL268A Listed for direct in air usage detector consists of a dust resistant photoelectric chamber and electronics with a low profile plastic housing Every FDO421 fire detector is shipped with a protective dust cover Operation FDO421 is a wide spectrum photoelectric smoke detector that an infrared light emitting diode IRLED as well as a light photodiode Under normal conditions light transmitted by the LED directed away from the photodiode and scattered through the smoke in a controlled pattern smoke chamber is designed to manage dissipation and extraneous reflections dust particles or other non smoke contaminants in such a way as to When smoke enters the detector light emitted from the IRLED is by the smoke particles and is by the photodiode see images on 2 Smoke Detector Model FDO421 Infrastructure Building Products Data Sheet 6152 usa siemens com fire Labyrinth Optical Optical Sensitivity Settings Parameter Sets FDO421 provides four 2 pre programmed sensitivity parameter sets that can be selected by the Siemens fire alarm panel in order to match the expected application or environmental conditions Dust cover Photoelectric FDO421 This application parameter set which is ideal for normal office hotel lobby type is the default setting This application parameter set is used when the detector is used a UL268A DI direct in air duct application without a duct housing FDO421 does not require a field sensitivity test Model FDO421 is UL Listed as a self testing and complies with NFPA 72 as a self monitoring detector and control panel arrangement This set is also used when Model FDO421 is used in air duct housings Models FDBZ492 and quick visual inspection is sufficient to indicate the condition of Model FDO421 at any time If more information is required a printed report can be provided from the compatible FACP indicating status and settings assigned to each individual detector When Model FDO421 moves to Alarm the detector will flash RED and continue flashing until the system is reset at the FACP At that time any user defined system alarm functions programmed into the system are activated FDO421 contains a tri color LED indicator capable of flashing any one 1 of three 3 distinct GREEN YELLOW RED During each flash interval the microprocessor based detector monitors following scenarios sensitivity is within the range indicated on the nameplate label in its sensing chamber sensors and electronics are functional on the results of the monitoring the LED indicator flashes the following INTERVAL COLOR seconds FLASH supervisory operation sensitivity is within rated limits is in trouble and needs replacement condition is not powered denotes LED can be turned OFF follow the corresponding description of the panel used Infrastructure Building Products quick visual inspection is sufficient to indicate the condition of the detector at any time If more detailed is required a printed report can be provided from the respective Desigo Fire Safety Modular XLS V FC FV20 FACP that indicates the status and settings assigned to each individual detector Installation Model FDO421 intelligent addressable detectors use a surface mounting base Model DB 11 or DB 11E which on a 4 inch 10.2 cm octagonal square or single gang electrical back box The base utilizes screw clamp for electrical connections and self wiping contacts for increased reliability Model DB 11 detector base can be used with the optional Siemens Model LK 11 detector locking kit which 50 detector locks and an installation tool to prevent unauthorized removal of the detector head Model DB has aesthetically conducive plugs to cover the outer mounting screw holes FDO421 may be installed on the same initiating circuit with the Siemens Model H detectors used with Desigo Fire Safety Modular FireFinder XLS V FC FV20 FACPs Data XTRI series interface modules HTRI series interface modules HMS XMS series manual stations HFP 11 HFPT 11 detection devices HCP output control module HZM conventional zone module detector which is shipped with a protective dust cover consists of the following Built in ISOtechnology for True Class X SLC performance Dust resistant photoelectric chamber Microprocessor based electronics with a low profile plastic housing Model FDO421 intelligent addressable detectors are approved for operation with the Underwriters Laboratories temperature range of 32 to 120 0 to 49 See installation manual P N A6V10323928 for further details Application Data of Model FDO421 smoke detectors require a two wire circuit In many retrofit cases existing wiring may be T tapping is permitted only for Style 4 Class B wiring Model FDO421 is polarity insensitive which can greatly installation and debugging times When
