Description and Intended Use
This 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 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).
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 beneath the pressure module and a HUD battery located in the HUD. The
system is switched on by pressing the buttons 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 the apparatus.
A wireless HUD unit (refer to instruction no. 3356234) located in the face mask
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.

CAUTION
Battery information:
Main battery – 7.5 V (5 x 1.5 V AA alkaline batteries)
Back-up battery – 3 V (CR123 lithium battery)
HUD battery – 3 V (CR123 lithium battery).
Use only the following approved battery types:
Procell by Duracell LR6 (1.5 V)
Duracell Plus LR6 (1.5 V)
Panasonic CR123AL/1BP (3 V).
Batteries are supplied with the equipment but are not fitted. Dräger
i i
recommend that the batteries be removed when the system is not used
for long periods as a small amount of discharge still occurs. The normal
NOTICE
operating life of the batteries is dependent on usage time, frequency of
alarms, backlight illumination and ambient temperature.
When the SCBA is in operational use; should the display screen switch off
i i
and the functionality of the HUD be powered by the back-up battery, then after
use of the SCBA Dräger recommend that the back-up battery is replaced.
NOTICE
The back-up battery will only supply power when the main battery is
i i
disconnected or discharged. When this occurs, the back-up battery will only
supply power for HUD functions.
NOTICE
Preparation for Use
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).
Installing the Back-Up Battery
 Orientate the SCBA to access the battery compartment.
 Unscrew and remove the battery cap (1, Fig 2), using a suitable coin.
 Insert the battery, +ve terminal end first, into the battery compartment.
 Refit and secure the battery cap. Do not overtighten.
Installing the Main Battery
 Inspect the sealing rim around the battery terminals. Ensure that the terminals of the
battery, and the pressure transmitter module, are clean and undamaged.
 Lift and turn over the SCBA to access the pressure transmitter module.
 Insert the battery pack into the backplate recess. Refer to Figure 3.
 Position thumbs on top of the two screws, push down firmly to lock the battery pack.
Refer to Figure 3 and 4.
 Whilst pushing down, confirm the two sliding locks move to their locked position
viewed through the two keyholes as illustrated. Refer to Figure 5.
 The Sentinel 7000 will emit a single tone and will commence the self-check
sequence (refer to Sentinel 7000 Self Check).
 Press and hold the RH and LH buttons of the user interface until the display clears,
then immediately release the buttons.
A battery check is performed during the self-check sequence. If the
i i
battery voltage is below a preset voltage the backlight will illuminate; the
low battery icon (Fig 6) will be displayed; the Sentinel 7000 will emit a
NOTICE
series of tones for approximately four seconds; and then the display will
switch off. When this occurs replace the battery.
To remove the battery insert and press the two pronged key (supplied
i i
with the SCBA) into the two keyholes at the base of the battery. This will
open the locking latch allowing the battery to be removed.
NOTICE
Installing the Cylinder
The following instructions are for a screw-on cylinder coupling. Installation
i i
of a quick-connect cylinder coupling is detailed in a separate UI (refer to
instruction no. 3356260).
NOTICE
 Set the carrying-frame backplate to the short (S) position (refer to Adjusting the
Backplate Height).
 Inspect and check the following:
The external thread of the cylinder valve port.
The internal thread of the first-stage regulator handwheel.
The O-ring seal in the pressure connector is in position and not damaged.
The bore to the sintered filter in the HP connector of the first-stage regulator is
clean and free from dirt and contamination.
 Lay the carrying frame horizontal and fully extend the cylinder strap.

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 7).
 Secure the strap using the Velcro fastening.
Adjusting the Backplate Height
 Lift the SCBA into the vertical position.
 Simultaneously press the two spring-loaded buttons (Fig 8) of the locking catch.
 Slide the yoke to the required position (short (S), medium (M) or long (L)) and
release the spring-loaded buttons.
 Grasp the yoke and the frame and attempt to raise and lower the yoke to confirm
that the locking catch is fully engaged.
Connecting the LDR and HUD
 Insert and push the male coupling of the LDR hose into the quick-release coupling
of the SCBA medium-pressure hose until it latches into position. Check the security
of the connection (do not connect the LDR to the face mask at this stage).
 Install a serviceable HUD into the face mask (refer to instruction no. 3356234).
