Autocall Electronic Heat Detectors for Two-Wire and Four-Wire Bases

Datasheet Initiating Peripherals Heat Detectors for Two Wire and Four Wire Bases Reference detectors are used where property protection is desired and life safety protection is not required or is performed by other Typical heat detector applications are satisfied by use of fixed temperature electronic detectors addition of rate of rise operation provides two forms of heat for use where temperature fluctuations are controlled and less than 6 F min 3.33 C min Where temperatures may fluctuate quickly use fixed temperature detection to NFPA 72 the National Fire Alarm Code and

protection of property listed to Standard 521 as a rate compensated heat detector temperature operation is suitable for most applications Thermistor based design is inherently rate compensated due to thermal lag Available for 135 F 57 C or 200 F 93 C UL and ULC spacing distance is 70 ft 21.3 m with rate of rise temperature detection Dual thermistor rate of rise operation For use where anticipated ambient temperature changes are less than F minute 3.33 C minute UL and ULC spacing distance is 70 ft 21.3 m encapsulated electronic design provides Operation for ceiling or wall mounting Easily tested self restoring operation with repeatable accuracy Alarm indicating LED located on detector Current limited alarm that is compatible with two wire initiating device IDCs Designed for EMI compatibility remote alarm indicating LED base options Bases for 2 wire or 4 wire operation Auxiliary relay output refer to selection chart on page 2 for relay Remote alarm indicating LED output Electronic Design electronic heat detectors use a fast response thermistor based to provide temperature sensing that quickly accurately and identifies when fixed temperatures are exceeded The temperature sensing thermistor readily tracks the local ambient This eliminates the time required to melt a lead pellet or a bimetallic element as occurs in mechanical heat detector designs provides the required heat detection for most applications detection detection is determined by comparing two thermistor By combining accurate thermistors with proper physical this patented rate of rise detection design achieves a high of performance not normally available with mechanical detection This product has been approved by the California State Fire Marshal CSFM pursuant to Section 13144.1 of
