DESCRIPTION
• The NightFighter Heads-Up Display System's Receiver
shows the user the air cylinder volume in one quarter
cylinder increments, from a full cylinder to an empty
cylinder, by a LED light logic pattern.
• The NightFighter Heads-Up Display System's
Transmitter is assembled to the gauge line hose. The
t
ransmitter or ICM Tx Unit sends a signal to the
r
eceiver (on the facepiece) of the air cylinder content.
•
The NightFighter Heads-Up Display System's Receiver
has seven (7) LED light patterns. (See Chart).
• The NightFighter Heads-Up Display System's Receiver
has a light sensor for that automatically adjusts the
brightness of the LED based on to the ambient light
levels measured outside of the facepiece.
• The NightFighter Heads-Up Display System's Receiver
will indicate a low battery by a Yellow LED light for the
receiver and transmitter. (See Chart).
• The NightFighter Heads-Up Display System operates
using two (2) standard AAA alkaline batteries in the
transmitter, or four (4) standard AA alkaline batteries if
the ICM Tx Unit is installed, and two (2) standard AA
alkaline batteries in the receiver. The NightFighter
Heads-Up Display System notifies the user when the
batteries need to be replaced.
• Use only Duracell MN2400, Energizer E92, or
Eveready A92 AAA alkaline batteries in the TRANS-
MITTER. Use of other batteries, or a combination
of batteries from different manufacturers, will
affect performance of the unit and will void the
intrinsic safety approval.
• Use only Duracell MN1500 or Energizer E91 AA
alkaline batteries in the RECEIVER. Use of other
batteries, or a combination of batteries from differ-
ent manufacturers, will affect performance of the
unit and will void the intrinsic safety approval.
• In older versions of the NightFighter RECEIVER con-
taining AAA alkaline batteries use only Duracell
MN2400, Energizer E92, or Eveready A92. Use of
other batteries, or a combination of batteries from
different manufacturers, will affect the perfor-
mance of the unit and will void the intrinsic safety
approval.
Failure to follow this war
ning can result in serious per-
sonal injury or death.
Note:
With system pressurized, quick press of the
Operation Button on the transmitter or mode button
(green) on the ICM Tx Unit will show current pressure for
ONLY 10 seconds.
• The LED lights in the receiver will automatically adjust
for the brightness outside of the facepiece.
• The receiver will indicate a Yellow LED light, after
going through the start up sequence, if a low battery
condition is detected in the receiver, transmitter, or
ICM Tx Unit. (See Low Battery Warnings).
Low Battery Warnings
Note:
There are different low battery warnings.
• If there is a low battery in the receiver, single Yellow
LED flash.
• If there is a low battery in the transmitter or ICM Tx
Unit, double short Yellow LED flashes.
• If there are low batteries in the receiver and transmitter
or ICM Tx Unit, the Yellow LED will alternate single
and double flashes.
The receiver will show air cylinder volume in 25% tank
increments from full to empty. (See Chart).
ICM TX UNIT
The ICM Tx Unit attached to the SCBA gauge hose. See
ICM Tx Unit Installation Instructions for proper installation
procedures.
The ICM Tx Unit is a multi-mode battery-powered, digital
pressure gauge, and serves as the transmitter for the
NightFighter Heads-Up Display System.
Note: The ICM Tx Unit does NOT have an audible low
pr
essure warning indicating that the cylinder has reached
25% ser
vice life.
Follow the procedures for the ICM Tx Unit outlined in the
ICM Tx Unit and NightFighter Heads-Up Display System
Operation and Maintenance Instructions (P/N 10058881).
