About the 4098-5611
The 4098-5611 is a conventional fixed temperature heat detector that alarms at 135°F (57.2°C), using a fast-response thermistor instead of a melting pellet or bimetal element. It connects to conventional 2-wire or 4-wire initiating device circuits through a compatible base. It is mounted on or close to the ceiling, indoors only.
Indoor use only; mount on or close to the ceiling, out of direct sunlight.
