Simplex 4098-9778
TrueAlarm heat sensors a r e 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 i s accurate. And quickly measures the local temperature for analysis at the fire alarm control panel.
Rate-of-rise temperature detection. Selectable at the control panel for 15° F (8.3° C) or 20° F (11.1° C) per minute. Fixed temperature sensing i s 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 initiates when the temperature reaches its rated fixed temperature setting.
TrueAlarm heat sensors a r e programmed as a utility device. To monitor for temperature extremes; in the range from 32° F to 155° F (0° C to 68° C). This feature can provide freeze warnings or alerts to HVAC system problems.
