Once stored, the information can be scrolled across the screen by pressing
the right button of the user interface (Fig B) during use.
The system is switched on by pressing the left and right buttons on the user
interface (Fig B), or by cylinder pressure detected at a pressure module in
the backplate, with pressure transmitted to the pressure module through a
high-pressure hose (Fig A, Item 3) when the cylinder is opened. At switch-
on, the unit performs a self-test (see Section 3.1.1), and once the self-test
is passed, the system adopts the active mode where the electronic
functions are operational.
The PASS alarm can be activated manually or automatically. The manual
alarm is activated by pressing the manual alarm button on the user
interface (Fig B, Item 2). The automatic alarm uses a motion sensor to
detect movement and activates a pre-alarm and main alarm at timed
intervals when no movement is sensed. The pre-alarm activates after 21-
25 seconds without movement, and the main alarm activates after
approximately a further 10 seconds without movement.
The HUD is fitted in the face mask to provide visual indications of system
conditions (see the HUD instructions for use for full details). Signals from
the Sentinel 7000 are transmitted to the HUD from a pressure transducer/
transmitter incorporated into the pressure module.
System power supplies are the main battery in the backplate, the backup
battery in the pressure module and the HUD battery in the HUD.
Dräger PC Link is an optional accessory that allows reading and
reprogramming of the Sentinel 7000. PC Link can reprogram settings and
parameters, including configuration, firmware and identification, and
download event record (datalog) information. Contact Dräger for full
details. The functions and parameters described in this document are the
default settings for the Sentinel 7000.
3.1.1 Sentinel 7000 start-up sequence and self-test
Each time the Sentinel 7000 switches on (with or without a compressed air
cylinder fitted), the Sentinel 7000 runs the self-test. During the self-test
sequence, the display scrolls through a series of screens and provides
start-up information and options, including:
● The main battery charge state.
● The electronic leak test option.
● The personal identity (scrolling data) option.
● If the system fails the self-test, the unit provides fail signal at the end
of the sequence.
The start-up sequence is:
1. The device emits a single tone from the user interface and the second
sounder, and the wait icon (Fig C) displays.
2. The tick icon (Fig D) displays and the blue, red, and green LEDs
illuminate.
3. The battery icon (Fig E) displays. The segments around the screen
indicate the condition of the main battery (all segments filled indicates
full battery).
4. The leak test icon (Fig F) displays. Pressing the left button (Fig B)
starts the optional electronic leak test procedure (see Section 4.6.5).
5. The personal identity icon (Fig G) displays. Pressing the left
button (Fig B) starts the procedure to read personal identity
information from a user ID card (see Section 4.6.6).
6. The automatic alarm icon (Fig H) displays and alarm tones sound.
7. End of sequence: the normal operating screen (Fig I) displays and the
green LED flashes at one second intervals.
3.1.2 Compressed air cylinders, lung demand valves, and face
masks

Users should be in a safe area before the whistle or end-of-service-time
warnings commence.
► Fully open all cylinder valves and ensure that they remain open during
use.
► Evacuate to a safe area immediately if warnings commence during an
operation.
● Regularly check the user interface display to confirm the exact cylinder
pressure and the remaining time until to the end-of-service time
(EOSTI) alarm activates (see Section 10 for the EOSTI activation
pressures). Both are shown numerically on the normal operating
screen (Fig I). Cylinder pressure is also shown as follows:
○ The HUD LEDs show the approximate cylinder pressure (see
Section 4.4.1).
○ The segments on the user interface screen show the approximate
cylinder pressure (Fig I).
● To call for emergency help or assistance, press the manual alarm
button in the center of the user interface (Fig B, Item 2) to activate the
manual alarm.
● To illuminate the display backlight, press and release the left or right
button of the user interface (Fig B).

○ Loss of HUD communication – The blue communication LED
(Fig M, Item 4) flashes.
WARNING
Using the bypass button (Fig J, Item 3) uses air from the cylinder and may
rapidly reduce the working duration of the apparatus.
► Do not use the bypass button unless absolutely necessary.
● If additional air is required, briefly press and release the bypass
button (Fig J, Item 3) to deliver a single jet of air into the face mask.
WARNING
The following emergency air flow procedures may greatly reduce the
operating duration of the air supply.
► When activated the user must immediately evacuate to a safe area.
► The reason for using the procedure must be investigated and repaired
before reusing the breathing apparatus.
● Additional air flow required (emergency procedure only used in the
unlikely condition of low or blocked airflow) – Press and rotate the
bypass button (Fig J, Item 3) to deliver a sustained air supply (85 to
130 liters/minute) into the face mask.
● Excessive or loss of air flow (emergency procedure only used in the
unlikely condition of high or loss of airflow) – Close the cylinder valve
then immediately begin to slowly reopen the valve. Use the cylinder
valve as a regulating valve to set the air flow to meet the user
requirement. This procedure can be used with screw-type and ratchet-
type cylinder valves.
