The Dräger PSSŽ 7000 is a compact and lightweight apparatus that provides the wearer
with respiratory protection when working in contaminated or oxygen-deficient conditions.
The system can be used as a self-contained system or with an independent air supply
to increase effective operation time. The system is fully compatible with a wide range of
compressed-air cylinders, face masks and lung demand regulators (LDRs).
Preparation for Use
The carrying system has a height-adjustable articulating backplate (6, Fig 1) that provides
improved comfort and ease of use, resulting in increased manoeuvrability and reduced
fatigue. The carbon-composite backplate incorporates a sliding height-adjustable yoke
that has three preset positions. A flexible pivot joint located at the base of the backplate
(in line with the hip of the wearer) moves in response to the twisting and bending of the
wearer, improving the weight distribution and freedom of movement. The system includes
adjustable shoulder straps (2) and waist belt (11).
Installing the Back-Up Battery
Take care to prevent impact damage as the cylinder valve is aligned with the first-stage
regulator handwheel.
Installing the Main Battery
 Insert the cylinder (valve end first) through the cylinder strap, to align the cylinder
valve with the handwheel.
 Lift the cylinder and backplate into the vertical position (supported on the end of the
cylinder).
 Align and fully tighten the handwheel (clockwise). Do not use tools or overtighten.
 Place the unit back into the horizontal position.
 Take up the slack of the cylinder strap and activate the cam-lock mechanism by
pulling the free end of the strap back over the cylinder (Fig 5).
 Secure the strap using the Velcro fastening.
The Sentinel 7000 electronic monitoring system is a multi-function system that provides
continuous monitoring of the SCBA status including remaining cylinder pressure,
movement of the wearer, main battery condition, end-of-service time (EOST) and
PASS. It provides visual indications of system status and audible and visual alarms
in warning conditions. User control and monitoring of the system is through a user
interface (1) that incorporates switches, LEDs, a liquid crystal display (LCD) display
screen and an alarm sounder. A backlight illuminates the user interface display screen
when required. Additional alarm sounders (5), with warning LEDs top and bottom, are
mounted on the backplate and operate only during PASS alarms. The operating settings
are preset and non-adjustable by the user.
The PASS function of Sentinel 7000 electronic monitoring system is an alarm system
that can be activated manually or automatically. The automatic alarm uses a motion
sensor to detect movement and activate a pre-alarm and main alarm at timed intervals
when no movement is sensed. The manual alarm is activated by a press button on the
user interface. A limitation of the PASS is that it detects movement or vibration to which
the wearer is subjected.
Power supplies include a main battery located in the backplate, a back-up battery
located the pressure module and a HUD battery located in the HUD. The system is
switched on by a press button on the user interface or by cylinder pressure felt at a
pressure module, with cylinder pressure transmitted to the pressure module through
a high-pressure hose (7). At switch on, a self test is performed and then the system
adopts the active mode where the PASS function is operational.
All variants utilise the same high-performance, first-stage, regulator (9) fitted with an
EOST mechanical whistle (10). The pressure regulator supplies medium-pressure
breathing air to a quick-release coupling (4) via a medium-pressure hose (3). Incorporated
in the first-stage regulator is a rapid intervention crew universal air connection (RIC UAC)
(8). The RIC UAC is a male coupling that allows emergency replenishment of breathing
air to the air cylinder while wearer is breathing from apparatus.
A wireless HUD unit (refer to instruction no. 3356234) locates in the face mask and
provides visual indications to the wearer of a number of system conditions. Signals from
the Sentinel 7000 to the HUD are from a pressure transducer/transmitter incorporated
in the pressure module.
Equipment configurations for non-CBRN use are detailed in a NIOSH Approval Table
(refer to instruction no. 3356261). Configurations for CBRN use are detailed later in
this instruction (refer to CBRN Use).

 Do not allow oil, grease or other contaminants to contact the RIC UAC connection.
 Do not attempt to disassemble or repair the RIC UAC connection.
 Caution: The secondary air supply pressure to the RIC UAC must not exceed maximum
rated working pressure of the cylinder(s) being filled.
 Caution: If the pressure relief valve of the RIC UAC is activated, the SCBA must be
returned to the nearest Dräger branch or agent.
 Caution: If a leak is detected while refilling in a contaminated or oxygen-deficient
gaseous atmosphere, stop refilling and immediately leave the hazardous area.

Cautions and Limitations
D – Air-line respirators can be used only when the respirators are supplied with respirable
air meeting the requirements of CGA G – 7.1, Grade D or higher quality.
E – Use only the pressure ranges and hose lengths specified in the User's
Instructions.
I – Contains electrical parts that may cause an ignition in flammable or explosive
atmospheres.
J – Failure to properly use and maintain this product could result in injury or death.
M – All approved respirators shall be selected, fitted, used, and maintained in accordance
with MSHA, OSHA, and other applicable regulations.
N – Never substitute, modify, add, or omit parts. Use only exact replacement parts in
the configuration as specified by the manufacturer.
O – Refer to User's Instructions and/or maintenance manuals for information on use and
maintenance of these respirators.
S – Special or critical User's Instructions and/or specific use limitations apply. Refer to
User's Instructions before donning.
CBRN Use
The Dräger PSSŽ 7000 Series is certified by National Institute for Occupational Safety
and Health (NIOSH), for limited chemical, biological, radiological or nuclear (CBRN)
use and by the Safety Equipment Institute (SEI) to meet the requirements of NFPA
1981. Approvals are only valid when the apparatus is used with compressed air cylinders
approved by NIOSH. Equipment configurations for CBRN use are detailed in a CBRN
Approval Label (refer to instruction no. 3356226).
If an FPS NFPA LDR, Dräger recommend that a quantitative fit test (QNFT) be performed
on the face mask before use in a CBRN environment. The fit test must be conducted
strictly in accordance with the requirements outlined in the OSHA Respiratory Protection
Standard 29 CFR, Section 1910.134.
Q – Use in conjunction with personal protective ensembles that provide appropriate levels
of protection against dermal hazards.
R – Some CBRN agents may not present immediate effects from exposure, but can
result in delayed impairment, illness or death.
T – Direct contact with CBRN agents requires proper handling of the SCBA after each
use and between multiple entries during the same use. Decontamination and disposal
procedures must be followed. If contaminated with liquid chemical warfare agents,
dispose of the SCBA after decontamination.
U – The respirator should not be used beyond 6 hours after initial exposure to chemical
warfare agents to avoid possibility of agent permeation.
S – Special or Critical Users’ Instructions
 Approved for use at temperatures above minus 25 degrees Fahrenheit (minus 31.7
degrees Centigrade).
 When used as a combination supplied-air respirator/self-contained breathing apparatus
(SAR/SCBA), not more than 20 per cent of the air supply can be used during
entry.
 During supplied air use, the cylinder valve must remain closed. If the supplied air
fails, open the cylinder valve and immediately proceed to fresh air.
 Supplied air source must meet the following criteria: pressure 87 – 125 psi, air flow
rate at least 550 litres/minute.
Important Note: If it is decided to exit the working area with the airline disconnected
or, in an emergency, if the air supply fails, breathe normally and immediately
proceed as follows:
 Open the cylinder valve (counterclockwise) slowly, but fully and breathe normally.
 Disconnect the hose of the independent air supply from the male coupling of the
airline hose connection. Breathe normally and immediately leave the hazardous area
by the shortest and safest route.
Safety Warning: The remaining duration begins from the time of opening the
cylinder valve and disconnecting the independent air supply. The time required to
allow the wearer to escape to a safe area must be within the remaining air capacity
(volume) of the cylinder taking into account the breathing rate of the wearer.
