<br /> a 15°F(8.3°C) per minute or a 20°F (11.1°C) per minute
<br /> rate of temperature rise The fixed temperature sensing
<br /> is entirely independent of the rate-of-rise operation. In a
<br /> slow developing fire, the temperature may not increase
<br /> rapidly enough to operate the rate-of-rise feature. -
<br /> However, an alarm will be initiated when the �
<br /> temperature reaches its rated fixed temperature setting.
<br /> The fixed temperature setting is selectable for a 117°F
<br /> (47.2°C) or a 135°F (57.2'C) alarm initiation.

<br /> WARNING: IN MOST FIRES, HAZARDOUS LEVELS OF SMOKE AND TOXIC GASES CAN BUILD UP BEF�RE
<br /> A HEAT DETECTOR WOULD INITIATE AN ALARM. IN CASES WHERE LIFE SAFETY IS A
<br /> FACTOR, THE USE OF SMOKE DETECTORS IS HIGHLY RECOMMENDED.
