Model MI-RHSE intelligent rate of rise temperature (Class A1R) sensors use a state-of-the-art single thermistor sensing circuit to provide early
warning of developing fires. These sensors are designed for open area protection and must only be connected to control panels that
use a compatible proprietary analogue addressable communication protocol for monitoring and control.
Two LEDs on each sensor light to provide a local 360° visible sensor indication. The LEDs can be latched on by code command from the control
panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code command. Remote LED indicator capability is
available as an optional accessory wired to the standard base terminals.
