Edwards Data Sheet CF CR Series Rate-of-rise, Fixed Temperature Heat Detectors

Edwards Signaling Catalog u Conventional Initiating Heat Series Series heat detectors offer fixed temperature or combina rate of rise and fixed temperature detection A temperature increase at the sensor of 15 or more per minute activates the rate of rise feature This the contacts in the sensor to transmit the alarm condition the fire alarm control panel When the rate of rise element alone been activated the sensor is self restoring TEMPERATURE If the temperature of the center disk to the sensor rated temperature the fixed temperature activates This closes contacts in the sensor and trans an alarm condition to the fire alarm control panel The fixed element is non restorable and when activated the must be replaced The need for replacement is indicated the center disk has fallen free from the detector Features Double pole normally open contact Low profile Aluminum finish Mounting flexibility with screw terminals Positive alarm indication for fixed temperature element 70 ft spacing CR models only detectors are most suitable for environments where rapid fire can be expected When selecting the location on the for the heat sensor do not locate it in direct path of hot or air flow Refer to the detector specifications for the recom maximum spacing Earlier detector response may be by reducing the spacing between detectors 1 of 2 D A T A S H E E T S85001 0367 to be used for installation purposes Issue 2.1 Series heat detectors are supplied a metal mounting plate The plate directly to a standard North Ameri 3 or 4 inch octagon box Once the plate is fixed a simple twist will the detector in place us 1 800 336 4206 www edwardssignaling com Signaling is EDWARDS brand Farm Glen Boulevard CT 06032 Canada contact Chubb Edwards Email inquiries chubbedwards com Web www chubbedwards com 2013 UTC Fire Security Americas Inc All rights reserved subject to change notice Edwards is part of UTC Controls Security a unit of Technologies Corporation Number Temperature Rating Max Ambient Temp Ceiling Type Recommended Recommended 57 93 57 93 38 66 38 66 Temperature and Rate of Rate of rise 15 F 9 C restoring Temperature Only ft 456 m ft 149 m ft 21.3 m ft 12.2 m Use For Property Protection Only Heat sen do not protect life against fire and smoke In most fires levels of smoke heat and toxic gases can build up a heat detector would initiate an alarm Independent indicate that heat detectors should only be used when protection alone is involved In cases where life safety a factor the use of smoke detectors is recommended no circumstances should heat detectors be relied upon the sole measure to ensure fire safety However if they are in accordance with the directions in the Specifica table these sensors can contribute within an overall safety program to reducing the risk of avoidable property Rating Maximum Distance Wall ft 6 m from any wall or extending down from ceiling more than 12 inches mm ft 10.5 m from any wall or extending down from ceiling more than 12 inches mm Pole Normally Open 3.0 amps at 125 Vac 1.0 amp at 28 Vdc amps at 125 Vdc 0.1 amps at 250 Vdc Dry ULC CSFM Environment Listings Maximum detector coverage has been determined by UL to provide detection time equal to sprinkler devices at 10 ft 3.05 m intervals on a smooth ceiling 15 feet 9 inches 4.8 m high Higher ceilings may affect detection time Earlier detection may be obtained by reducing the spacing between sensors NFPA 72 Chapter 5 information Detector 135 57 Rate of Rise and Fixed Temperature Detector 200 93 Rate of Rise and Fixed Temperature Detector 135 57 Fixed Temperature Only Detector 200 93 Fixed Temperature Only Wt kg lb 0.5 2 of 2 D A T A S H E E T S85001 0367 to be used for installation purposes Issue 2.1
