Kidde Edwards Data Sheet K85001-0589 - Rate Compensation Heat Detectors

Rate Compensation Detectors Series mount Mount 302 heat detectors are designed for use in normal environ as well as environments where the detectors are subject to moisture internal condensation and explosive atmo They are normally open devices designed to close an circuit upon activation All models feature rate compen and are available with either 135 57.2 or 194 90 ratings They are self restoring hermetically sealed shock and resistant and are tamperproof Features Rate compensation offsets thermal lag Self restoring no manual reset required Explosion proof and weatherproof models available Weatherproof models available that do not require a special Box mount and surface mount models available rated at 135 57.2 will not respond to momentary fluctuations less than 30 between 60 and 100 38 Sensors rated at 194 90 will not to momentary temperature fluctuations less than 50 between 60 16 and 150 66 302 Series sen should not be used in environments where conditions exceed parameters Do not install them in hot air ducts in front of in paint booths that use heat to cure paint or any other subject to temperature fluctuation Rated 57.2 90 Ambient Temperature 40 40 Ceiling 38 66 sensor aluminum tube acts as a heat collector when sourc of heat radiate directly on the tube Install these sensors out of sunlight and away from radiating heat sources including the flow from heaters and heat ducts 1 of 4 D A T A S H E E T K85001 0589 to be used for installation purposes Issue 1 Catalog u Conventional Initiating DevicesTechnology that saves livesfirealarmresources com Compensation Series sensors feature rate compensation which improves by offsetting thermal lag an inherent property of fixed temperature heat sensors slow rate of temperature rise allows the heat to penetrate the expansion struts The tubular shell and the struts expand until the total device has been heated to its rated tempera level of 135 57.2 or 194 90 At this point the contact points close and an alarm is initiated subjected to a rapid rate temperature rise there is not as time for heat to penetrate the inner strut However the rapid of the shell allows the struts to come together at a level the surrounding air temperature returns to below the rated the shell contracts forcing the contacts to open thus auto resetting the sensor Wiring control or device Rating VAC VDC VDC 302 Series Detectors of amps amp amp silver contact struts expansion sensing 0.040 anodized aluminum control sleeve screw hermetic seal Series heat sensors are low maintenance Sensors automati restore when temperatures drop below their rated tempera The accumulation of dust and dirt does not normally affect sensors operation for operation is simple and can be done before or after the has been installed Heat the sensor with a hair dryer do use any device with an open flame to test sensors The sen should operate shortly after the hot air is applied to NFPA 72 National Fire Alarm Code and or the local

initiate an alarm Independent studies indicate that heat sensors should only used when property protection alone is involved In cases where life safety is a factor the use smoke detectors is recommended no circumstances should heat detectors be relied upon as the sole measure to ensure fire However if they are spaced in accordance with the specifications found under Application sensors can contribute within an overall fire safety program to reducing the risk of avoid property losses used with automatic fire suppression systems such as pre action and deluge sprinkler carbon dioxide systems halon systems and dry chemical systems at least two sen should be used to initiate the alarm This is commonly referred to as cross zoning or priority zoning and is necessary to eliminate premature discharge of the system Refer to NFPA 72 more information D A T A S H E E T K85001 0589 to be used for installation purposes Issue 1 Information Interior applications Detector Rate
