2 Description and Intended Use
This User Instruction (UI) describes the Dräger PSS® 7000 Series of SCBA fitted
with the following:
A Dräger Sentinel 7000 electronic monitoring system, with integral personal
alert safety system (PASS).
A Dräger wireless head-up display (HUD) unit.
The Dräger PSS® 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).
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 heightadjustable 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).
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).
Sentinel 01: Edition 1: July 2008 - Subject to Modification
Page 9
D
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.

!
requirements for Type 1 gaseous air as defined in the CGA Commodity
Specification for Air, G-7.1 (Grade D or higher quality) and where appropriate
be in accordance with: NFPA 1989 Standard on Breathing Air Quality for
Emergency Services Respiratory Protection.
Recharge cylinders to the indicated working pressure marked on the
!
cylinder.
If the moisture content exceeds the recommended levels, ice particles can
!
form, reducing or blocking the airflow.
9 Cleaning the SCBA
Use only recommended cleaning agents. Do Not use organic solvents, such
!
as acetone, alcohol, white spirit, trichloroethylene or similar. Do not use
any form of mechanical, electrical or ultrasonic agitation in cleaning baths.
Refer to manufacturers’ instructions when using cleaning and disinfecting agents.
Particular attention should be paid to concentration and reaction times.
Do not exceed 86 °F for washing and rinsing solutions. Do not exceed 140
!
°F for drying. Do not immerse the LDR.
Recommended cleaning and disinfecting agent is liquid AirKem A-33. Full
i
i
details of cleaning and disinfecting agents are available from Dräger on
request.
Carefully clean SCBA components (use suitable cleaning baths, and immerse and
manually agitate components in solution as necessary).
Thoroughly remove any cleaning solutions by rinsing in clean water.

11 Special instructions
Use of an Independent Air Supply (SAR Airline Connection)
Air quality must conform to the statutory requirements.
!
Use of an airline connection by a second person (buddy-breather) voids NIOSH
approval.
The time required for the wearer to escape to a safe area must be within the remaining
breathing time of the cylinder, taking into account the remaining air content in the
cylinder and the breathing rate of the wearer.
Independent air supplies must meet the following standards:
Type-1 gaseous air as defined in: CGA Commodity Specification for Air, G-71 (grade
D or higher)
NFPA 1989 Standard on Breathing Air Quality for Fire and Emergency Services
Respiratory Protection
Air supply pressure – 87 psi to 125 psi
Airline hose length – 5 feet to 300 feet (maximum working hose length must not exceed
12 individual hose lengths)
Airline flow rate – 550 litres/minute
Approved for use at temperatures above minus 25 degrees Fahrenheit (minus 31.7
degrees Centigrade).
Sentinel 7000 alarms and warning signals will operate as normal.
i
i
The user interface display will show cylinder pressure when the cylinder valve
is open.
Turn on the independent air supply.
Connect the independent air supply coupling to the secondary supply hose (refer to
instruction no. 3355853) and breathe normally.
Close the cylinder valve (if the EOST warning signal activates, silence by taking several
short deep breaths or momentarily operating the LDR bypass button (3, Fig 13).
If any air supply problems are encountered, proceed as follows:
Open the cylinder valve to return to breathing from the attached cylinder.
Disconnect the independent air supply coupling.
Leave the hazardous area by the shortest and safest escape route, if necessary.
12 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.
Sentinel 01: Edition 1: July 2008 - Subject to Modification

PSS® 7000 SERIES c/w SENTINEL 7000 EMU
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.
13 CBRN Use
The Dräger PSS® 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.
23
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.
14 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.
Sentinel 01: Edition 1: July 2008 - Subject to Modification

PSS® 7000 SERIES c/w SENTINEL 7000 EMU
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.
15 RIC UAC Use
Use of the RIC UAC should be by trained and competent personnel only.
The RIC UAC filling hose is a required component of the NFPA 1981 certification.
Only use a filling hose which has been certified to NFPA 1981 for use in immediately
dangerous to life or health (IDLH) atmospheres.
Do not use the RIC UAC connection for second person (buddy-breather).
Do not use the RIC UAC support pack to transfer air from one compressed air breathing
apparatus to another.
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.
