MSA FireHawk M7 Responder Operation And Instructions Manual page 8

The pressure gauge continuously shows the air pressure
in the cylinder.
The handwheel is used to open and close the cylinder
valve.
AUDI-LARM ALARM WITH URC ASSEMBLY
The Audi-Larm Alarm rings when there is approximately
25% of the air mask's rated service time remaining and
when the cylinder valve is first opened, providing an audi-
ble indication that the alarm is working properly.
A high pressure hose delivers air at cylinder pressure from
the Audi-Larm Alarm to the PR14 First Stage Regulator.

All FireHawk M7 Responder Air Masks are equipped with
an Audi-Larm Alarm that includes a URC Assembly
(Universal Rescue Connection). The URC Assembly is a
male quick-fill inlet for use by Rapid Intervention Crews
for emergency filling of the SCBA or during transfill opera-
tions. Also included with the URC Assembly is a pressure
relief valve for protection of the cylinder burst disc.

ULTRA ELITE RESPONDER FACEPIECE
The facepiece includes a dual-mode exhalation valve.
When the facepiece is not connected to the FireHawk M7
Responder regulator, the exhalation valve operates as a
demand exhalation valve. When the facepiece is connect-
ed to a pressurized FireHawk M7 Responder regulator, the
exhalation valve operates as a pressure-demand exhala-
tion valve.
The facepiece lens is super-hardcoated to meet the
requirements of NFPA 1981.
The facepiece has a low-resistance, pressure-demand
exhalation valve.
An inhalation check valve in the inlet housing keeps mois-
ture and contaminants out of the Firehawk Responder
Regulator.
The facepiece has a speaking diaphragm for clear com-
munication.
The facepiece has a nose cup with a drink tube and can
be used with the SpeeD-ON® Head Harness.
The facepiece has a plug for the side port that must be
attached during use.
DO NOT use this facepiece without the facepiece plug
installed. Failure to follow this warning can result in
serious personal injury or death.
FIREHAWK M7 RESPONDER HUD
The FireHawk M7 Responder HUD, located on the Ultra
Elite Facepiece allows a user to see cylinder pressure in
one quarter cylinder increments, PASS pre-alarms, battery
status, and telemetry information (optional) while wearing
the air mask.
FIREHAWK M7 CONTROL MODULE (PASS DEVICE)
The FireHawk M7 Control Module is the user's interface
with the air mask.
The FireHawk M7 Control Module is equipped with an
analog gauge as well as an LCD to provide the user vital
information: numeric and iconic cylinder pressure, battery
status, thermal alarm (optional), and time remaining.
If the air mask is equipped with the optional FireHawk M7
Telemetry Module, the radio link status and evacuation
alarms are displayed.
