Overview Photoelectric Thermal Heat Detector Model FDOT421 is an intelligent multi criteria detector that incorporates optical and thermal sensors and signals in a neural network to create an intelligent multi criteria detector The result is a detector that provides enhanced detection to a wide range of of combustion FDOT21 is UL 268 7th Ed listed and incorporates advanced built in True Class X SLC operation use is optional greatly improves circuit integrity and provides advanced addressable fault finding multi criteria detector additionally has state of the art microprocessor with error check as well as detector self diagnostics and supervision that is used on Desigo Fire Safety Modular FireFinder XLS V and on FC FV20 series Desigo Fire Safety fire alarm control panels FACPs Model FDOT421 is a plug in and addressable two wire multi criteria with both photoelectric and thermal sensors whose value is increased built in ISOtechnology feature that is compatible with all current Siemens addressable systems Operation FDOT421 utilizes an infrared light emitting diode IRLED and infrared photodiode Under normal conditions light transmitted by the LED directed away from the photodiode and scattered through the smoke chamber a controlled pattern smoke chamber is designed to manage light dissipation and extraneous from dust particles or other non smoke airborne contaminants in such way as to maintain stable consistent detector operation When smoke enters detector chamber light emitted from the IRLED is scattered by the smoke and is received by the photodiode FDOT421 also utilizes a modern accurate and shock resistant thermistor to temperature changes signal processing with detection algorithms the detector to first gather smoke and thermal and then analyze this information in the neural network By comparing data with the common characteristics of fires or signatures Model FDOT421 can compare these to those of deceptive phenomena that cause detectors to trigger a false alarm Model FDOT421 Fire Detector Model FDOT421 detector provides three 3 pre programmed parameter sets can be selected by the FACP Infrastructure Building Products Sheet 6150 usa siemens com fire Labyrinth Optical Optical Heat sensor Dust cover Multi criteria detector Each detector consists of a photoelectric a solid state non thermal sensor microprocessor based with a low profile housing Every Model FDOT421 detector is shipped with protective dust cover Model FDOT421 Profile Overview FDOT421 provides two 2 different alarm sources that can be selected individually ON or OFF by the control Source 1 Neural Network Combines smoke heat with the following field selectable profiles Standard Duct This parameter set which is practically ideal for normal office hotel lobby type applications is the default This parameter set additional offers improved resistance to false alarms in areas where misleading sources and helps reduce cooking nuisance alarms UL 268 7th Ed Listed When using this detector direct in air duct applications be sure the detector is set to the parameter Source 2 Thermistor Heat only provides the following Static fixed at 135 57 default setting Rate of Rise detection at 15 min 8.3 min the detector is not programmed Model FDOT421 will default to a profile setting which allows operation a normal office type environment Model FDOT421 contains a tri color LED indicator capable of flashing any one of three 3 distinct colors GREEN YELLOW RED During each flash interval the microprocessor based detector the following fire system conditions Smoke in its sensing chamber Smoke sensitivity is within the range indicated on the nameplate label Internal sensors and electronics Based 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 quick visual inspection is sufficient to indicate the condition of the detector at any time more detailed information is required a printed report can be provided from the respective Desigo Fire Safety Model FC20 series FireFinder XLS V FACPs that indicates the status and settings assigned to each detector Infrastructure Building Products usa siemens com fire Installation Model FDOT421 detectors use a surface mounting base Model DB2 HR DB 11 or Model DB 11E Each base onto a 4 inch 10.2 cm octagonal square or single gang electrical 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 11 aesthetically conducive plugs to cover the outer mounting screw holes FDOT421 may be installed on the same initiating circuit with the following when used with Desigo Fire Safety Model FC20 series FireFinder XLS V FACPs XTRI Series interface modules HTRI series interface modules HMS XMS series manual stations HFPT 11 detection devices output control modules conventional zone module Data detector is shipped with a protective dust cover consists of the following Built in ISOtechnology for True Class X SLC performance Dust resistant photoelectric chamber Solid State non mechanical thermal sensor Microprocessor based electronics with a low profile plastic housing Model FDOT421 detectors are approved for operation within the UL specified temperature range of 32 to 100 38 Data of Model FDOT421 addressable multi criteria detectors requires a two wire circuit many retrofit cases existing wiring may be used T tapping is permitted only for Style 4 Class B wiring FDOT421 is polarity insensitive which can greatly reduce installation and debugging times When operating in 72 C
