Simplex 4098-9733 Analog Heat Detector and 50 similar items

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. Refer to specific panels for availability.
