Thermal Alarm
WARNING!
Although the thermal alarm provides an indication that the temperature/time curve is exceeded,
because of variations in individuals and protective clothing, the curve may not represent the
threshold to injury accurately. Use the thermal alarm only as a reference to increasing tempera-
ture/time. Do not use the thermal alarm as a substitute for standard operating procedures for
escape from temperature/time extremes.
Failure to obey this warning can result in serious personal injury or death.
If the option for the thermal alarm is activated, the control module monitors thermal conditions.
The thermal alarm can be set as a primary or secondary (default) alarm. If the user is exposed to
more than the preset limit of thermal load (temperature/time), the secondary alarm shows on the
control module and the power module emits a tone every 5 seconds.
The following figure shows the thermal alarm activation curve for the control module. The
temperature/time limits correspond to this graph. The thermal alarm activates if the preset limit
exceeds the curve shown on the graph. Depending on the severity of conditions, the alarm will
self-cancel. This may occur even though the temperature is above the thermal curve.
