HEAT DETECTOR

SHORT DESCRIPTIONS

4098-9733, 4098-9789 HEAT DETECTOR WITH BASE, SSD HEAT SENSOR
BRAND: SIMPLEX, ORIGIN: USA, CERTIFICATION: UL LISTED
FEATURES:
Sealed against rear airflow entry, Interchangeable mounting, EMI/RFI shielded electronics, Selectable rate compensated, fixed temperature sensing with or without rate-of-rise operation

TrueAlarm 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 (8.3° C) or 20° F (11.1° C) per minute. 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 initiated when the temperature reaches its rated fixed temperature setting. TrueAlarm 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). This feature can provide freeze warnings or alert to HVAC system problems
