DESCRIPTION
FIREHAWK M7 TELEMETRY MODULE
The FireHawk M7 Telemetry Module provides the firefight-
r with two-way communication with Incident Command.
e
The firefighter’s vital statistics such as cylinder pressure,
service time remaining, PASS alarm, low battery alarm,
and thermal alarm are transmitted back to Incident
Command. Also, the firefighter has the ability to be evac-
ated remotely by Incident Command. The radio trans-
u
mitter is located inside of the FireHawk M7 Power
Module.
EXTENDAIRE SYSTEM
The ExtendAire System, located on the user’s left chest,
enables two users to share a common air supply during
emergency escape. The users can couple the Firehawk
Second Stage Regulator from one user to the intermediate pressure manifold of the other user. Both users will
receive intermediate pressure air from the donor's first
stage regulator and cylinder. The duration of the remaining
air supply will be reduced by at least half.
he SCBA is approved by NIOSH without inter-connecting
T
two users to one apparatus. NIOSH does not certify
buddy breathers”. Therefore, the attachment of the
“
receiver's regulator to the donor's apparatus voids the
NIOSH approval for both air masks.
RESCUE BELT
The MSA Fire Service Rescue Belt is a personal escape
system integrated into an FireHawk M7 Carrier and
Harness Assembly. The system is designed to provide the
user a means of escape from an elevated position. Use of
the Rescue Belt must be in accordance with the user’s fire
department procedures. Care and use instructions are
provided under a separate manual, P/N 10052748.

possible after use. Cylinders should not be stored
partially charged for two reasons:
• If used without recharge, the service life of the air
mask is reduced.
• The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
b. If the cylinder is less than FULL (within 10% of
rated service pressure), recharge it before storage.
Cylinder air must be at least CGA Quality
Verification Level (Grade) D respirable air. In fire service applications, MSA recommends breathing air
quality in accordance with NFPA 1989.
c. Inspect the cylinder valve for signs of damage. The
valve may be opened slightly to ensure it operates
properly. Be sure to fully close the valve.
d. Inspect the cylinder body for cracks, dents, weak-
ened areas, corrosive agents causing the fibers to
break or peel, or signs of heat-related damage. If
the cylinder is damaged return it to an MSA Service
Center.
e. Check the hydrostatic test date on the cylinder
approval sticker located on the cylinder neck.
Fiberglass composite cylinders must be tested
every three years. Carbon-wrapped and steel cylinders must be tested every five years.
f. Ensure the needle and gauge face on the cylinder
valve gauge are clearly visible and that the gauge
stem is not bent.
It is also essential that the required inspections and tests
be performed on all air mask cylinders in accordance with
Department of Transportation (DOT) regulations. DOT regulations require that composite cylinders be retired from
service after the fifteenth year. This does not include cylinder valve assemblies that may be reused. Steel and aluminum cylinder service life is indefinite if proper inspection and hydrostatic test procedures are followed and they
indicate that the cylinder may remain in service. Contact
an MSA distributor or sales associate for more information
regarding this policy.
Note: ANSI Z88.5 recommends checking cylinder pressure weekly. For maximum safety the cylinders should be
stored full or empty (pressure above ambient but less than
100 psi).
9. FireHawk M7 Carrier and Harness
. Operate the latch wing on the cylinder band to
a
ensure that it opens and closes properly and that it

11. FireHawk M7 Power Module
a. Inspect the FireHawk M7 Power Module housing for
external cracks and ensure that the FireHawk M7
Power Module, battery tube, and cylinder stop are
securely attached to the backplate.
b. Inspect the piezo emitters on both sides of the
FireHawk M7 Power Module. Ensure that the emitter covers are not obstructed by dirt or debris.
c. Ensure that the power cable is securely attached to
the FireHawk M7 Power Module. The fitting on the
power cable should not be able to be unthreaded
by hand.
d. Remove the cap from the battery tube. Ensure that
the o-ring is properly installed on the battery cap, if
o-ring is missing, it must be replaced.
e. Inspect the inside of the battery tube. Ensure that
the battery terminals are not corroded and that the
tube if free of moisture and debris.
f. Replace the battery cap on the battery tube.
12. Record Keeping
a. Following inspection, the date and initials of the
designated inspector should be recorded on an
inspection tag. A more detailed record of the operations performed can be noted on an inspection and
maintenance log, available from MSA. When the
inspection data has been recorded, the air mask is
ready for use.
All repair and replacement of subassemblies must be
carried out by an MSA certified repair technician.
Failure to follow this warning will void NFPA and
NIOSH certifications and can result in serious personal injury or death.
