4. Evacuation 

status

• The RED and YELLOW arrows and GREEN check

mark display the status of an evacuation signal.  

• When an evacuation signal is sent by the base sta-

tion, the “evacuate” or “running man” icon will turn
RED and a black dot will appear next to the RED
arrow.  

• When the ICM TxR Unit has received the signal, the

running man icon will turn YELLOW and a black dot
will appear next to the YELLOW arrow.  

• When the firefighter manually confirms the evacua-

tion command, the running man icon will turn
GREEN and a black dot will appear next to the
GREEN check mark.  

5. Alarms

• If an ICM TxR Unit goes into a motion alarm, manu-

al alarm, temperature alarm, 25% pressure alarm, or
low battery alarm, a window will pop up displaying
this warning.

The SCBA monitoring software has the ability to send an
evacuation command to firefighters that are logged on to
the system.  This command can only be sent to a fire-
fighter once during a single SCBA monitoring session.   

Three Types of Evacuations
1. Evacuate 

All 

a. To evacuate all firefighters logged on to

a base station; click the “Evacuate All”
button in the upper portion of the SCBA monitoring
window.  
• When the evacuation signal is sent to all SCBAs,

the “Evacuate All” button will turn RED.  

• When each ICM TxR Unit receives the evacuation

command, the PASS device will begin to emit an
audible evacuation alarm, display a flashing run-
ning man icon on the LCD, display alternating
RED/ORANGE LEDs in the NightFighter® Heads-
Up Display System receiver, and the evacuate icon
for that firefighter will turn RED on the PC screen.

• When an ICM TxR Unit successfully receives the

evacuation signal, it automatically returns a signal
to the base station to confirm that the signal has
been received.  If the signal is not received, the
base station will continue to send a signal to that
unit until the radio transmission is successful.

• When the base station receives a confirmation sig-

nal from an ICM TxR Unit that the evacuation com-
mand has been received, the Evacuate icon for
each firefighter will turn YELLOW on the PC screen.  

b. The firefighter must then manually press the reset

button on the ICM TxR Unit twice in rapid succes-
sion in order to acknowledge the evacuation com-
mand and silence the evacuation alarm.  
• As each firefighter manually acknowledges the

evacuation command, the Evacuate icon for each
firefighter will turn GREEN.  

• When all firefighters have manually acknowledged

the evacuation command, the “Evacuate all” but-
ton will turn GREEN.  

2. Evacuate 

Team

a. To evacuate a single team of firefighters 

logged on to a base station; click the 
“Evacuate” button in the team window.  
• When the evacuation signal is sent to the entire

team, the “Evacuate” button in the team window
will turn RED.  

• When each ICM TxR Unit receives the evacuation

command, the PASS device will begin to emit an
audible evacuation alarm, display a flashing run-
ning man icon on the LCD, display alternating
RED/ORANGE LEDs in the NightFighter receiver,
and the evacuate icon for that firefighter will turn
RED on the PC screen .  

• When an ICM TxR Unit successfully receives the

evacuation signal, it automatically returns a signal
to the base station to confirm that the signal has
been received.  If the signal is not received, the
base station will continue to send a signal to that
unit until the radio transmission is successful.

• When the base station receives a confirmation

signal from an ICM TxR Unit that the evacuation
command has been received, the Evacuate icon
for each firefighter will turn YELLOW on the PC
screen.  

• When the base station has received a confirma-

tion signal from all members of the evacuated
team, the “Evacuate” button in the team window
will turn YELLOW.   

b. The firefighter must then manually press the reset

button on the ICM TxR Unit twice in rapid succes-
sion in order to acknowledge the evacuation com-
mand and silence the evacuation alarm.  
• As each firefighter manually acknowledges the

evacuation command, the Evacuate icon for each
firefighter will turn GREEN.  

• When all firefighters in the evacuated team have

manually acknowledged the evacuation com-
mand, the “Evacuate” button in the team window
will turn GREEN.  

3. Evacuate
