Brand New SIMPLEX 4098-9402 RATE OF RISE HEAT DETECTOR 135 RR Direct

Description

Brand new in packaging
4098-9402 SIMPLEX LIFEALARM HT DET 135 RR DIRECT.
Accurate Electronic Design. Simplex® electronic heat detectors use a fast response, thermistor based design to provide temperature sensing that quickly, accurately, and consistently identifies when fixed temperatures are exceeded. The fixed temperature sensing thermistor readily tracks the local ambient temperature. This eliminates the time required to melt a lead pellet or heat a bimetallic element as occurs in mechanical heat detector designs and provides the required heat detection for most applications. Accurate thermal detection for protection of property** UL listed to Standard 521
Available with rate-of-rise temperature detection:
Dual thermistor rate-of-rise operation
For use where anticipated ambient temperature changes are less than 6° F/minute
UL spacing distance is 70 ft
Epoxy 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 circuits (IDCs)
Direct connecting design:
Wiring attaches directly to detector terminals
Detector mounts onto mechanical adapter plate (supplied)
Rate-of-rise detection is determined by comparing two thermistor responses. By combining accurate thermistors with proper physical placement, this patented rate-of-rise detection design achieves a high level of performance not normally available with mechanical detection.
Heat detectors are used where property protection is desired and where life safety protection is not required or is performed by other equipment. Typical heat detector applications are satisfied by use of these fixed temperature electronic detectors.
