DESCRIPTION
This kit supplies the parts required to install the ICM Tx
and TxR Units on MMR SCBA from MSA. You can install
this kit if the SCBA is an MMR. For a full description of
the ICM Tx and TxR Units, please refer to the ICM Tx and
TxR Units and Nightfighter Heads-Up Display User’s
Instructions, P/N 10058881(P/N 10068930 for ICM TxR
Unit)
The ICM Tx and TxR Units functions as a PASS Device,
pressure gauge, and as the transmitter for the
NightFighter Heads-Up Display System.
An SCBA cannot be upgraded until the following
inspection and all required changes have been com-
pleted. Failure to follow this warning can result in seri-
ous personal injury or death.
NFPA-1500:1997 COMPLIANCE INSPECTION
Inspect the entire SCBA after it is cleaned and sanitized.
NFPA-1500, as well as ANSI Standards Z88.2 and Z88.5,
describe three levels of inspection procedures which are
to be performed. Refer to these documents, or to an
inspection program prepared by a health professional in
establishing an inspection program.
Do not inspect the apparatus before cleaning if there
is danger of contacting hazardous contaminants.
Clean and disinfect first, then inspect. Failure to follow
this warning can cause inhalation or skin absorption
of the contaminant and result in serious personal
injury or death.
Prior to installation of the ICM Tx or TxR Units, the SCBA
must be upgraded to be compliant with the 2002 edition
of the NFPA-1981 standard. This standard requires the
use of the NightFighter Heads-Up-Display receiver with
either the NightFighter Transmitter or the ICM Tx or TxR
Units. The components must be in good working order,
free of damage and significant wear. (See SCBA
Inspection Instructions). This standard requires the SCBA
to have a URC fitting located within 4 inches of the cylin-
der valve.

INSTALLATION
If the MMR has the shoulder mounted quick-fill option, do

from the system. Open the bypass valve to release any
trapped air. Removing the pressure gauge with the
system pressurized can result in serious personal
injury or death.
