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 publication A4098 Detectors, Sensors, and Bases Application Manual, for guidance in applying and locating heat detectors. Current Current, 2-Wire Current, 4-Wire Operation Range 1: General Specifications to 32 VDC (filtered DC with 30% ripple) typical, 100 maximum to 86 mA maximum, exact current is by alarm current limiting of IDC mA typical @ 24 VDC FM requirements for operation 15 and 25 F/min (8.33 and C/min) to 95% RH from 32 to 122 F (0 50 C), not intended for outdoor to 140 F (-18 C to 60 C) to Temperature Temperature Operating Range F Models F Models to 100 F (0 to 38 C) to 150 F (0 to 66 C) ** In most fires, hazardous levels of smoke and toxic gas build up before a heat detection device would initiate an alarm. In where Life Safety is a factor, the use of smoke detection is highly Temperature Guidelines F (57 C) fixed temperature detectors are for normal temperatures do not exceed 100 F (38 C). F (93 C) fixed temperature detectors are for normal temperatures exceed 100 F (38 C) but are less than 150 F (66 C). Indicating LED Operation heat detector LED turns ON continuously when in alarm. During conditions the LED is OFF. ULC, CSFM Listed, FM 1: Heat Detector Mounted in Base and reliable heat detection for 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.
