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.\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FIRE ALARM SYS","offers":[{"title":"Default Title","offer_id":51571162939712,"sku":"395253089610","price":43.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/6466\/0032\/files\/2a31b9aafce7dd48c639c541f8b3a9a7.jpg?v=1772129479","url":"https:\/\/firealarmsys.com\/products\/simplex-4098-9778-same-day-shipping-sealed","provider":"FIRE ALARM SYS","version":"1.0","type":"link"}
