Silent Knight SK-PTIR-W Multi-Criteria Detector Data Sheet

SK PTIR W Photo Thermal Infrared Detector SK PTIR W is an intelligent multi criteria that combines photoelectric thermal infrared PTIR sensors in one unit to multiple components of a fire multi sensor approach on the SK PTIR W replaces the SK ACCLIMATE enables sensitivity to real fire with heightened immunity to nuisance particulates Multiple and communication can greatly reduce nuisance alarms compared to single methods Sophisticated algorithms maximize the advantages of all four sensor creating our best detection strategy offering heightened immunity to nuisance and enhanced sensitivity to real fire Photoelectric sensor detects airborne particles associated with smoke Thermal sensor detects heat and rate of rise 135 fixed temperature threshold Infrared sensors discern light patterns in the environment as an additional data point for alarm ability to reject certain nuisance alarm triggers such as theater smoke supports the use the detector in applications where moderate to heavy nuisance conditions exist that cause single sensing detectors to trigger a false alarm PTIR detector meets both UL 268 7th edition and UL 521 listing requirements and can distinct smoke and heat alarms This dual nature supports a local alarm setting for detection and a general evacuation setting based on thermal detection This minimize work interruptions in multi level buildings AND BENEFITS UL 268 7th Edition and UL 521 Listed Multi criteria detection Analog communications Low standby current Rotary address switches Dual LEDs for 360 visibility New modern profile Expanded color options TECHNICAL SPECIFICATIONS Height 2.0 inches 51 mm installed in base Diameter 6.2 inches 156 mm installed in base 4.1 inches 104 mm installed B501 WHITE IV BL base Weight 3.4 oz 95 g Humidity Range 15 90 Humidity Non condensing Temperature Range 32 0 38 Velocity 0 300 ft min 0 91.4 m min Voltage Range 15 to 32 VDC Current 24 VDC 200 uA one every 5 seconds with green blink on communication Alarm Current 2 mA 24 VDC communication every 5 seconds with LED solid on Current 4.5 mA 24 VDC one every 5 seconds with amber solid on Load Rating 0.0063 devices in this datasheet meet the of UL 268 7th Edition LISTINGS AND listings and approvals below apply to SK PTIR W In some cases certain may not be listed by certain agencies or listing may be in Consult the factory for the latest status UL S6173 FM Approved CSFM 7272 0559 0517 INFORMATION Multi criteria photoelectric and infrared smoke detector white 4 Mounting base white 4 mounting base white 4 Mounting base ivory 4 Mounting base black 6 Flanged mounting base white 6 Flanged mounting base 10 pack 6 Flanged mounting base ivory Intelligent addressable sounder white Intelligent addressable sounder ivory Intelligent addressable base low frequency white Intelligent addressable sounder low frequency ivory Isolator base white Isolator base ivory Relay base white Relay base ivory Surface mounting kit flanged Trim ring white Trim ring ivory IR color kit includes cover and ring white 10 pack IR color kit includes cover and ring ivory 10 pack IR color kit includes cover trim ring black 10 pack Remote LED annunciator Detector test magnet Telescoping test magnet Silent Knight Clintonville Road CT 06472 1610 C 07 19 Honeywell International Inc Knight is a registered of Honeywell Inc All rights reserved use of this document strictly prohibited document is not intended to be for installation purposes We to keep our product information and accurate We cannot all specific applications or all requirements All are subject to change notice of origin Mexico
