Simplex 4098-9402 Rate of Rise Heat Detector

The Simplex 4098-9402 is a combination sensor between a Rate-of-Rise and a Thermal Sensor. The Simplex 4098-9402 is also compatible with various Fire Alarm Control Panels. Simplex electronic heat detectors use a fast response, thermistor based which is design to provide temperature sensing that quickly, accurately, and consistently identifies when fixed temperatures are exceeded. Additionally, the fixed temperature sensing thermistor readily tracks the local ambient temperature. Consequently, 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. Furthermore, heat detectors are used where property protection is desired and where life safety protection is not required or is performed by other equipment. Moreover, typical heat detector applications satisfy the use of these fixed temperature electronic detectors. Especially, this heat sensor is compatible with various Fire Alarm Control Panels. Also, 135° F (57° C) fixed temperature detectors are for normal temperatures that do not exceed 100° F (38° C).
