Cerberus Pyrotronics DT-135R F 200R F Thermal Fire Detector 6130

Thermal Fire Detectors AND ARCHITECT SPECIFICATIONS Listed Cerberus Pyrotronics Thermal Fire Detectors are fixed or combination fixed temperature rate of rise The combination detectors consist of two indepen operated thermal elements The rate of rise element self restoring However the fixed temperature is of the type Laboratories Inc recommends the combi type thermal detector be used to protect a maxi of 2,500 square feet and the fixed temperature type used to protect a maximum of 625 square feet Job and engineering judgment however often closer spacing to provide faster detection Principle of Operation rate of rise element consists of an air chamber a metal diaphragm and a moisture proof trouble free which is carefully calibrated is well known that air expands as it is heated and con as it is cooled For normal day to day fluctuations of the expansion and contraction of the air the chamber is automatically compensated by the action of the vent when a fire occurs air temperatures rise very and the air in the chamber expands faster than it be vented This creates a pressure which distends the and closes electrical contacts Data NUMBER rate of rise action is not related to any fixed tempera level but responds with the utmost promptness when rate of temperature rise exceeds 15 per minute If the is removed the air within the chamber contracts and switch moves to a normally open circuit position Temperature Principle of a slow developing fire the temperature may not in rapidly enough to operate a rate of rise element cases such as described a fixed temperature principle operation is desired detector utilizes a fixed temperature element made fusible alloy and is of the non restorable type fusible alloy will melt and activate the detector when surrounding air rises above the preset level of 135 200 Information external heat collector drops away when the detec is activated therefore giving a quick visual confirma that the detector has alarmed detector includes a thermoplastic reversible mount plate In one position it easily attaches to a 4 octagon box 3 octagon box or plaster ring reverse the plate can be used for open wiring without a box A 1 4 space between detector and mounting allows for wire connections All mounting screws concealed detector simply attaches to the mounting plate with a and twist motion No tools required and Architect Specifications thermal fire detector shall be a Cerberus Pyrotronics number It shall operate at a of degrees F insert temperature The shall be listed by Underwriters Laboratories and Factory Mutual for use with Cerberus Pyrotron systems No No T 1 3 5 F T 1 3 5 F T 2 0 0 F T 2 0 0 F e s c r i p t i o n e s c r i p t i o n and fixed 135 and fixed 200 temperature 135 temperature 200 p p l i c a t i o n s p p l i c a t i o n s temperature and ceiling not 100 temperature and ceiling not 100 violent fluctua and ceiling not 100 violent fluctua and ceiling exceed 100 but not d e n t i f i c a t i o n d e n t i f i c a t i o n Heat Heat o l l e c t o r o l l e c t o r Information RING SPOT SPOT RING Pyrotronics Ridgedale Avenue Knolls NJ 07927 201 267 1300 201 397 7008 in U S A Pyrotronics East Pearce Street Hill Ontario 1B7 CN 905 764 8384 905 731 9182 1995 sheet dated 3 94
