AUDI-LARM ALARM WITH URC ASSEMBLY
The Audi-Larm Alarm rings when there is approximately
2
5% 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
t
he Audi-Larm Alarm to the PR14 First Stage Regulator.
Note: The remaining service time calculations are based
on a 40 LPM (liters per minute) NIOSH breathing rate.
All FireHawk M7 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 emer-
gency filling of the SCBA or during transfill operations.
Also included with the URC Assembly is a pressure relief
valve for protection of the cylinder burst disc.
FIREHAWK M7 CARRIER AND HARNESS ASSEMBLY
DO NOT use this carrier and harness assembly as a
vertical raising or lowering device. Failure to follow
this warning can result in serious personal injury or
death.
The carrier consists of a backplate, a cylinder band with
latch to hold the cylinder, and a harness, consisting of
shoulder pads, chest strap (optional), adjustable pull straps,
waist belt, waist belt mounted regulator retainer, swiveling
lumbar pad (optional), and Rescue Belt (optional).
ULTRA ELITE FACEPIECE
The facepiece is available in three sizes (Small, Medium,
and Large).
The facepiece lens is super-hardcoated to meet the
requirements of NFPA 1981.
The facepiece has a low-resistance, pressure-demand
e
xhalation valve.
A
n inhalation check valve in the inlet housing keeps mois-
ture and contaminants out of the Firehawk Regulator.
The facepiece has a speaking diaphragm for clear com-
munication.
FIREHAWK M7 HUD
The FireHawk M7 HUD, located on the Ultra Elite
Facepiece allows a user to see cylinder pressure in one
quarter cylinder increments, PASS pre-alarms, battery sta-
tus, 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.
The integrated PASS motion sensor is housed within the
FireHawk M7 Control Module.
FIREHAWK M7 POWER MODULE (PASS DEVICE)
The FireHawk M7 Power Module on the lower portion of
the backplate houses the batteries, serves as the cylinder
stop, emits audible PASS alarms, and has buddy lights.
The FireHawk M7 Power Module is linked to the FireHawk
M7 Control Module via the power cable.
OPTIONAL FIREHAWK M7 AIR MASK COMPONENTS
CLEAR COMMMAND COMMUNICATION SYSTEM
The Clear Command Communication System is an elec-
tronic speech projection system available with either an
amplifier or an amplifier with radio interface connection.
