1. Dust cover 1 2. Thermal(heat)detector 1. Thermistor NOTE:Each detector consists of a dust-resistant chamber;a solid state, functional internal sensor,and 6 microprocessor-based electronics with a low-profile plastic housing. i rA Every Model FDT421 fire detector r shipped with a protective dust cover.. rr 2 Detector Supervision Model FDT421 contains a tri-color LED indicator, capable of flashing any one (1) of three (3) distinct colors: GREEN RED. During each flash interval, the microprocessor-based detector monitors the following fire-system conditions: • Temperatures reaching programmed thresholds • Internal sensors and electronics are functional Based on the results of the monitoring, the LED indicator flashes the following: FLASH COLOR CONDITION FLASH INTERVAL [in seconds] Normal supervisory operation. GREEN*: Temperature has not reached programmed 10 alarm thresholds or set points. YELLOW: Detector is not operating at 4 normal capacity and needs replacement. IFAlarm'condition 1 NO FLASH: Detector is not powered. — *denotes LED can be turned OFF Please follow the corresponding description of the panel used. A quick visual inspection is sufficient to indicate the condition of the detector at any time. If more detailed information is required, a printed report can be provided from the respective Desigo Fire Safety Modular FireFinder XLSIV or Model FC20-series FACPs that indicates the status and settings assigned to each individual detector. All Model FDT421 detectors use a surface-mounting base, Mode[ DB-1 1 or Model DB-1 1 E, which mounts on a 4-inch (10.2 cm.) octagonal, square or single-gang electrical box. The base utilizes screw-clamp contacts for electrical connections and self-wiping contacts for increased reliability. The Model DB-11 detector base can be used with the optional Siemens Model LK-1 1 detector locking kit,which contains 50 detector locks and an installation tool to prevent unauthorized removal of the detector head. Model DB-11 has aesthetically conducive plugs to cover the outer mounting-screw holes. Model FDT421 may be installed on the same initiating circuit with the Siemens Model 'H'-series detectors and devices [when used with Desigo Fire Safety Modular I Model FC20-series I FireFinder XLSIV FACPs] — • HFP-11, HFPT-11 • Model 'XTRI'-series interfaces • Model 'XMS'-series manual stations • Model 'HTRI'-series interfaces • Model HMS'-series manual stations • Model'HCP' -output control modules • Model 'HZM'-series of addressable,conventional zone modules Siemens Smart Infrastructure - Building Products —2— usa.siemens.comlfire
