ICM TX UNIT THERMAL ALARM (THERMISTOR)
DEVICE TECHNICAL SPECIFICATIONS
Although this thermal alarm provides an indication
that the time-temperature curve is exceeded, the
curve may not represent the threshold to injury due to
variations in individuals and the protective clothing
worn. Use this alarm as a reference only to increasing
time-temperature. Do not use as a substitute for stan-
dard operating procedures regarding escape from
time-temperature extremes. Failure to do so can result
in serious personal injury or death.
The ICM Tx Unit can monitor temperature conditions if the
Thermal Alarm option is purchased. If the wearer is
exposed to more than a pre-set limit of time/temperature,
the unit will sound a tone every 3 seconds.
