Description and Intended Use
ThisUIdescribestheDrägerPSS®7000SeriesofSCBAtted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-decientconditions.
The system can be used as a self-contained system or with an independent air supply
toincreaseeective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exible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,rst-stage,regulator(9)tted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
rst-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.
