Model MI-RHDE rate of rise thermal detectors use dual thermistor sensing elements for ambient temperature compensation and fast response. These detectors are designed to provide open area protection and to be used with compatible control panels only. The ability to plug these detectors into a variety of base options extends panel compatibility and application flexibility. Two LEDs on each detector light to provide a local 360° visible alarm indication. Remote LED annunciator capability is available as an optional accessory wired to the standard base terminals. These detectors also have a latching alarm feature. The alarm can be reset only by a momentary power interruption. These detectors may be tested by activating an internal reed switch with a magnet
