The Simplex 4098-9734 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 accurately and quickly measures the local temperature for analysis at the fire alarm control panel.
Rate-of-rise temperature detection is selectable at the control panel for either 15° F or 20° F per minute. Also, fixed temperature sensing is independent of rate-of-rise sensing and programmable to operate at 135° F (57.2° C) or 155° F (68° C). The 4098-9734 sensor provides an additional 190° F (88° C) set point.
In a slow-developing fire, the temperature may not increase rapidly enough to operate the rate-of-rise feature. However, an alarm will be initiate when the temperature reaches its rated fixed temperature setting. Besides, Simplex 4098-9734 heat sensors can be programmed as a utility device to monitor for temperature extremes in the range from 32° F to 155° F (0° C to 68° C). Furthermore, this feature can provide freeze warnings or alert to HVAC system problems.
