Simplex A4098-9733E

E-Series Analog Heat Sensor 4098-9733E and Bases for Extended Exposure to High Humidity 4098-9733 heat sensors are self-restoring and provide rate compensated, fixed temperature sensing, selectable with or without rate-of-rise temperature sensing. Due to its small thermal mass, the sensor’s thermistor accurately and quickly measures the local temperature for analysis at the fire alarm control panel.
