Model MI-FHSE intelligent fixed temperature (Class A1S) 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.
Operating Voltage Range: 15 to 32 VDC Max. Standby Current: 200μA @ 24 VDC (no communication) Max. Avg. Standby Current: 300μA (one communication every 5 sec. with LED blink enabled) Max. Alarm Current (LED on): 7 mA @ 24 VDC Operating Humidity Range: 10% to 93% Relative Humidity, noncondensing Temperature Range: -30°C to 80°C Nominal Activation Temperature: 58°C Height: 51 mm installed in B501 Base Diameter: 102 mm installed in B501 Base Weight: 78 g
