Chart 3 shows the ICM Tx Unit thermal alarm activation
curve. The time/temperature limits are based on the
curve. The thermal alarm sounds if the pre-set limit
exceeds the curve. The alarm will self-cancel depending
on the severity of conditions. This may occur even though
the temperature is above the thermal curve.

hart 3: ICM Tx Unit Thermal Alarm Activation Curve
Note:
This chart was generated from data obtained in a
laboratory setting and is for reference only. Conditions
are highly variable in an actual use scenario. Users of the
ICM Tx Unit with the thermal alarm option should develop
procedures for the use of this feature.
Optional ID Tag (PN 10058545), for use with ICM Tx
Unit
The purpose of the ID Tag is to associate a user ID or
jump seat location with the ICM Tx Unit. Once the ICM
Tx Unit has read the ID data from a tag, that ID will remain
associated with all future sessions of the ICM Tx Unit until
another ID Tag has been swiped.
The ID Tag has a space for the user to place a label in
which the ID information can be written on the outside of
the ID Tag for easy identification. This space is located
on the side of the ID Tag opposite the appr
oval label.
Any label attached to the ID tag must be less than 4
squar
e centimeters in total area, other
wise the intrin-
sic safety approval is void.
Before using the ID tag, inspect for damage or cracks
in the case. If damage is found, discar
d and replace
the ID tag.
Failur
e to follow these warnings can result in serious
personal injury or death.

Functional Check of the ICM Tx Unit
1. Don the SCBA following the instructions in the SCBA
User’s Instruction Manual.
2. When opening the cylinder valve to perform the SCBA
“system checks,” listen for the ICM Tx Unit automatic
activation indicator as described in table.
3. Look through the facepiece lens at the LED panel, the
LEDs should illuminate through the startup sequence
as the SCBA is pressurized. The startup sequence is
as follows:
a. Four Green LED’s ON/OFF.
b. Three Green LED’s ON/OFF.
c. Two Yellow LED’s ON/OFF.
d. One Red LED ON/OFF.
e. One Yellow LED ON/OFF.
f. Current cylinder pressure.
4. Look to verify that the GREEN light on the ICM Tx Unit
is slowly flashing.
5. Stand motionless for approximately 20 seconds.
Listen for the pre-alarm to sound the low volume
r
epeated tones. Look for the RED light on the ICM Tx
Unit to alternately flash slowly.
6.
Remain motionless until the full alarm activates. Listen
for the alarm to sound the increasing loud repeated
tones. Look for the light to flash RED rapidly.
7. Reset the ICM Tx Unit by pushing the RESET button
on the side of the unit 2 times within appr
oximately 1
second.
8. To check manual activation of the full alarm, push and
HOLD the alar
m button on the front of the unit.
9. Reset the Alarm. Press RESET button 2 times within
appr
oximately 1 second.
