AUDI-LARM ALARM WITH URC ASSEMBLY
DO NOT connect a high pressure air mask to a sec-
ondary air supply with a pressure greater than 4500
psi. The high pressure air mask is rated for a maxi-
mum working pressure of 4500 psi. Misuse can result
in serious injury or death.
NOTE: Rapid Intervention Crews should use a separate
air supply such as MSA’s RescueAire portable air supply
system to fill the air mask in an IDLH atmosphere.
1. Connect the quick-fill hose to the secondary air supply.
a. Turn the air supply on.
If there are leaks from either female fitting, or along
the hose, depressurize the hose and correct the prob-
lem. Such leakage can result in increased fill time.
2. Attach the quick-fill hose to the URC Assembly.
a. Remove the rubber dust cap from the male inlet fit-
ting on the URC Assembly. Be sure that the cylinder
valve is fully opened.
b. Remove the rubber dust cap from the female fitting
on the quick-fill hose.
c. Push the female fitting of the hose onto the male fit-
ting of the URC Assembly until it snaps in place.
Pull on the hose to be sure the connection is
secure. Filling immediately begins when the female
fitting fully engages with the URC Assembly.
d. After approximately 45-60 seconds, the pressure
between the secondary air supply and the air mask
cylinder will be equal.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Misuse can result in serious injury or death.
NOTE: If the secondary air supply does not have a suffi-
cient volume of air, the air mask cylinder will not reach full
service pressure.
3. Compare the cylinder pressure gauge, the FireHawk
M7 Control Module pressure gauge (integrated PASS
version), or the NightFighter transmitter pressure
gauge (without integrated PASS version) to the sec-
ondary air supply pressure gauge reading. If the read-
ings are the same, pressure is equal.
4. To disconnect the quick-fill hose after transfilling, pull
the gray sleeve back. The hose fitting and the URC
Assembly will separate. A hiss or pop may be heard
as the fittings separate and the high pressure air is
sealed off.
5. Immediately install the dust cover on the URC
Assembly.
6. The air mask cylinder is ready for service if the cylin-
der pressure gauge needle is on the appropriate color
band.
TRANSFILLING BETWEEN AIR MASKS
NOTE: The air mask with the higher pressure reading is
the donor. The air mask with the lower pressure is the
receiver. Transfilling between users of air masks should be
performed only during life-threatening emergencies or sim-
ulated training exercises. Both donor and receiver must
return to fresh air immediately following the procedure.
DO NOT transfill if the donor's audible alarm is ringing
or FireHawk M7 HUD or I-HUD /FireHawk M7 Control
Module (integrated PASS version) are flashing. Failure
to follow this warning can result in shorter escape
time to return to fresh air, causing serious personal
injury or death.
The audible alarm begins ringing and heads-up display
system begins flashing to indicate that the pressure in the
cylinder has been reduced to 25% of its rated working
pressure. Remaining service time must be used for
escape to fresh air. If the donor's audible alarm begins
ringing or FireHawk M7 HUD or I-HUD/FireHawk M7
Control Module (integrated PASS version) begins flashing
during transfilling, the donor should disconnect and pre-
serve his escape time.
1. If the donor's alarm is not ringing and FireHawk M7
HUD or I-HUD/FireHawk M7 Control Module (integrat-
ed PASS version) are not flashing and you have suffi-
cient air to transfill to a receiver, (greater than 1000 psi
for 2216 psi air masks and greater than 2000 psi for
4500 psi air masks), follow these steps.
a. Remove the 3 foot emergency transfill hose from its
protective pouch.
b. Remove the rubber dust cover from both female fit-
tings on the transfill hose assembly.
c. Remove the rubber dust cover from the URC fitting.
d. Push the female fittings on to the male fittings until
they click in place. Pull on the hose to be sure it
snapped in place.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Misuse can result in serious injury or death.
e. After approximately 45-60 seconds, pressure
between the air mask cylinders will be equal.
f. Disconnect the transfill hose from the air mask by
pulling the gray sleeve back on both ends. A hiss or
