s Fire Detectors Fire Detectors DT 135R DT 135F DT 200R and DT 200F FM Approved Overview Siemens Building Technologies Fire Safety Thermal Fire Detectors are fixed or a combination of fixed rate of rise type The combination consist of two independently operated elements The rate of rise element is However the fixed temperature of the non restoring type Laboratories Inc recommends combination type thermal detector be used to a maximum of 2,500 square feet 50 foot and the fixed temperature type be used protect a maximum of 625 square feet 25 foot However job conditions and judgment often dictate closer to provide faster detection thermal fire detector shall be Fire Safety insert number It shall operate a temperature of insert The detectors shall be listed by Laboratories Inc and Factory for use with Siemens Building Fire Safety Division systems Technologies Safety Security Products Principle of Operation rate of rise element consists of an air a flexible metal diaphragm and a trouble free vent that is carefully is well known air expands as it is heated and contract as it is cooled For normal day to fluctuations of temperature the expansion contraction of the air within the chamber is compensated by the of the vent when a fire occurs air temperatures rise rapidly and the air in the chamber expands than it can be vented This creates a which distends the diaphragm and electrical contacts rate of rise action is not related to any fixed level but responds with the utmost when the rate of temperature rise 15 per minute If the heat is removed air within the chamber contracts and the moves to a normally open circuit position Fire Detectors 6130 continued Temperature Principle of Operation a slow developing fire the temperature may not rapidly enough to operate a rate of rise Therefore a fixed temperature principle of is needed detector utilizes a fixed temperature element of fusible alloy and is of the non restorable fusible alloy will melt and activate the detector the surrounding air rises above the preset of 135 or 194 external heat collector drops away when the is activated therefore giving a quick visual that the detector has alarmed detector includes a thermoplastic reversible plate In one position it easily attaches to 4 octagon junction box 3 octagon box or ring reverse the plate can be used for open wiring a junction box A 1 4 space between and mounting surface allows for wire All mounting screws are concealed detector simply attaches to the mounting with a push and twist motion no tools required for Ordering This marketing catalog sheet is not intended to be used for system design or installation purposes the most up to date information refer to each product installation instructions Technologies Safety Security Products Safety Security Fernwood Road Park NJ 07932 973 593 2600 973 593 6670 www SBT Siemens com FIS in U S A Safety Security Derry Road West Ontario 7A6 Canada 905 799 9937 905 799 9858 2009 sheet dated 11 02
