3 Description
3.1 Product
overview
The Dräger Bodyguard
®
7000 (Fig. 1) is an electronic monitoring system
with an integral DSU. The system provides visual and audible information
about the status of the breathing apparatus. Visible signals are provided
by LEDs in the LED panel and on the LCD screen of the user interface
(Fig. 2). Audible signals are emitted from an electronic sounder in the
user interface. The audible signals are easily recognized with varying
sound patterns to distinguish between different alarm types.
The product is configured as a button version (Bodyguard
®
7000) or a
tally version (Bodyguard
®
7000T). The main difference between the
version types is the functionality of the distress signal unit. The button
version can be used with the motion sensor of the automatic distress
alarm deactivated. The tally version can only be used with the motion
sensor activated.

3.2 Feature
description
3.2.1 Power pack
The power pack connects to the pressure module to supply power to the
electronic monitoring system. The power pack types available for
Bodyguard
®
7000 have 5 replaceable 1.5 V batteries or a single 6.5 V
rechargeable battery.
Further details about the power pack and how each type is used is in the
maintenance information (see section 6.5).
3.2.2 User interface
The user interface has an LCD screen which shows the cylinder
pressure, the time until the whistle activates, and other operational
information. The screen has a backlight which illuminates when a user
interface button is pressed, when an alarm activates, and when a status
message appears on screen. The LED panel has one green, two blue,
and two red LEDs which illuminate or flash to provide operational
information.
The left-hand and right-hand press buttons are used to control operating
features of the electronic system. The button functions are described
where applicable in these instructions for use.
An internal sounder emits audible signals to notify the user about
breathing apparatus alarms and status messages. The sound patterns
include continuous alarms and single or multiple tones. The sounder
uses the tally slots as amplification chambers to provide clear and loud
alarms.
3.2.3 Cylinder pressure monitoring
The pressure module is connected to the breathing apparatus pneumatic
system through the high-pressure hose. The electronic monitoring
system displays cylinder pressure and TTW, and provides alarm signals
at preset pressure levels.
Time to whistle
The TTW is the calculated time in minutes until the EOST alarm
activates. The system uses the breathing apparatus air cylinder pressure
and the current consumption rate of the wearer to calculate and display
TTW. An initial calculation is made using a default consumption rate of
40 L/min. The calculation is then updated once per second based on the
actual consumption rate of the wearer (a minimum consumption rate of
40 L/min is applied to the calculation).
At the preset pressure, the EOST alarm commences (see section 4.2.3).
The mechanical whistle on the breathing apparatus also commences at
approximately the same time.
Retreat alert
Retreat alert is an alternative warning protocol that is available if it is
applicable in the country of use (see section 4.5.5).
3.2.4 Distress signal unit
The DSU provides automatic and manual distress alarms. The automatic
distress alarm uses an internal motion sensor and timer to measure the
time that the wearer has been motionless, in order to indicate that the
wearer may be unconscious or trapped. The motion sensor activates a
pre-alarm and a full alarm at predetermined intervals when the wearer
does not move in excess of normal breathing movement. The manual
distress alarm is activated by pressing the manual alarm button to call for
help or attention. The alarm activation times are in section 9, and the
alarm patterns are in section 4.2.3.
A limitation of the automatic distress alarm is that the motion sensor
detects movement or vibration to which the wearer is subjected. If the
wearer is motionless but on a moving platform (on moving or vibrating
machinery for example) the automatic distress alarm might not activate.
3.3 Optional features and equipment
3.3.1 Dräger PC Link
Dräger PC Link is an RF communication device and software application
which can read and configure Dräger electronic monitoring systems.
Configurable settings and parameters include alarm patterns, warning
levels, timings, and the start-up options (see section 4.4.3). Readable
information includes the product identification details, the firmware
versions, and a datalog (see section 3.3.2).
PC Link can also read and write information on user ID cards which are
available from Dräger for use with Bodyguard
®
See the PC Link instructions for use or contact Dräger for more
information.
The settings specified in these instructions for use (pressures, alarm
patterns, start-up options, etc.) are the default configuration settings for
Bodyguard
®
7000.
3.3.2 Datalog
The datalog is a record of the event history which is automatically
recorded in the system memory. The datalog stores approximately
20 hours of the most recent system events (based on typical operational
use of the system and the default datalog recording interval of
20 seconds). The datalog can be downloaded and viewed using Dräger
PC Link.
3.3.3 Telemetry (Dräger PSS
®
Merlin
®
)
Dräger PSS
®
Merlin
®
is a telemetry system which can be used with
Dräger electronic monitoring systems. When fitted, the telemetry system
is used to monitor and control breathing apparatus wearers that are
deployed at an incident. The telemetry system uses radio communication
to transmit status and information signals between deployed breathing
apparatus wearers and an external entry control board or software
system. See the PSS
®
Merlin
®
instructions for use or contact Dräger for
more information.
3.3.4 Head-up display
The Dräger FPS
®
7000 HUD is a wireless head-up display which can be
used with Dräger electronic monitoring systems. The HUD is a battery
powered device that fits inside the mask, and has LEDs which display
breathing apparatus cylinder pressure and battery status information.
See the FPS
®
7000 HUD instructions for use or contact Dräger for more
information.
3.4 Intended
use
Bodyguard
®
7000 is intended for use as an electronic monitoring system
on compatible Dräger breathing apparatus. The monitoring system
provides accurate cylinder pressure and remaining time information, and
activates alarm signals at critical pressures. The integrated DSU provides
clear, distinct, and easily recognized alarm signals that indicate wearer
immobilization or a call for help or attention.
3.5 Use in potentially explosive atmospheres
Bodyguard
®
7000 is type tested as suitable for use in potentially
explosive atmospheres. Electronic sub-assemblies are ATEX certified. All
combinations are suitable for use in hazardous areas up to and including
zone 0 and zone 20.
