Cerberus Pyrotronics Explosion Proof Thermal Fire Detector (Detect-A- Fire) 6128

Thermal Fire Detectors Proof Models Proof Models AND ARCHITECT SPECIFICATIONS AND ARCHITECT SPECIFICATIONS MODELS Explosion Proof Self Restoring Detector Element Models Available in both Normally Open Normally Closed Contacts in a Wide of Temperature Settings Factory Set and Hermetically Sealed in Steel Shell and FM Approved as Fenwal Series 27120 and 27121 for Cerberus Pyrotronics Fenwal explosion proof detectors are of the rate type and are designed for use with either Cerberus Pyrotronics systems or other commer available fire alarm systems The detector element all models is self restoring after operation The Detect explosion proof models can be supplied with closed contacts at 140 160 190 210 225 275 360 or 450 settings or with normally open contacts 140 160 190 210 275 325 360 450 500 600 or settings These detectors are only explosion proof mounted in an approved explosion proof junction of Operation of Operation units have met with wide acceptance they are designed with rate compensation This a unique advantage over both standard fixed and rate of rise types of detectors because the Detect A Fire unit accurately senses the surround air temperature regardless of the fire growth rate At the predetermined danger point the system is secret of the unit sensitivity is in the design The shell is made of a rapidly expanding alloy which follows changes in surrounding air temperature inner struts are made of a lower expanding alloy to resist thermal energy absorption and sealed the shell the struts follow temperature changes slowly slow rate fire will heat the shell and struts together At point the unit will trigger actuating the alarm or the extinguishant transient rush of warm air up to 40 may expand shell but not enough to trigger the unit In ignoring warm air excursions the Detect A Fire unit eliminates false alarms prevalent with rate of rise a fast rate fire starts then the shell will expand rapidly struts will close actuating the alarm or releasing the The faster the fire rate of growth the sooner the and Architect Specifications and Architect Specifications explosion proof thermal fire detector shall be a Detect explosion proof model Fenwal also for purposes referred to as Cerberus Pyrotronics and shall be of the rate compensated type explosion proof detector shall have a self restoring and shall be factory set and hermetically sealed in steel These detectors shall be mounted in an explosion proof junction box explosion proof detectors must be UL listed and FM NUMBER Cross Reference Chart Open Contact Closed Contact 27121 140 27120 140 27121 160 27120 160 27121 190 27120 190 27121 210 27120 210 27121 225 27120 225 27121 275 27120 275 27121 325 27120 325 27121 360 27120 360 7 8 7 8 7 8 7 8 7 8 10 10 10 15 20 25 15 27121 450 27120 450 27121 500 27121 600 27121 725 Normally Closed Contact Detectors do not operate with any Cerberus Pyrotronics Control These Normally Closed Contact Detectors are offered for special applications only Information Information to the chart above When placing a purchase order to the Cerberus Pyrotronics model number The of the model number is DT the temperature desired EP For example if you wish to order a open 140 detector you would order model DT 140EP The Cerberus Pyrotronics model DT 140EP and DT 190EP both normally open stocked items All other models are special orders Cerberus Pyrotronics Customer Service Depart for assistance Shipping weight for these items is one pound and Installation Information and Installation Information explosion proof EP models attach to the threaded cover of listed explosion proof junction boxes such as Series UL or equal The EP models should not be in outdoor or other wet locations Setting 140 7 160 7 190 7 White 210 7 White 225 7 450 15 275 10 325 10 360 10 500 15 600 20 725 25 in Feet Note B I Groups B and D II Groups E and G Model Required for UL ULC Listings and FM detector to a listed fitting in withthe Electric Code local authority jurisdiction Pyrotronics Ridgedale Avenue Knolls NJ 07927 201 267 1300 201 397 7008 www cerbpyro com Units have a stainless steel sensing shell and a brass mounting head Model No Series Closed Series Open Rating Only Amps 125 VAC Amps 125 VDC Amps 125 VAC Amps 125 VDC Amps 24 VDC Amps 48 VDC in U S A Pyrotronics East Pearce Street Hill Ontario 1B7 CN 905 764 8384 905 731 9182 1997 sheet dated 1 95
