3-2.5.2.4.11 How to Change a Thermal Detector’s Pre-Alarm and Alarm Thresholds
Purpose: To change the pre-alarm and alarm thresholds of one or more
thermal detectors. The thermal detector is UL Listed and FM Approved
for alarm reporting anywhere in the range of 135° F to 155°F when
used with a 50-foot spacing, or anywhere in the range of 135°F to
145°F when used with a 70-foot spacing. Alarm thresholds can be set
in 1F° increments. A pre-alarm threshold can also be set anywhere
within the temperature range of 80°F to 135°F, but must be less than
the detector's alarm threshold.
The alarm ranges for the thermal detectors are summarized below:
Spacing (ft.)
Pre-Alarm Range
(°F)
Alarm Range (°F)
50 80 - 135 135 - 155
70 80 - 135 135 - 145
