2 Description
2.1 Product overview
The Dräger PSS 5000 Series is a compact and lightweight breathing
apparatus that provides the wearer with respiratory protection using an
open-circuit, pressure-demand, compressed-air system. The apparatus
can be used as a self-contained system, or with an independent air supply
for supplied-air respirator (SAR) operations. The series is compatible
with a wide range of Dräger compressed-air cylinders and face masks
(e.g. FPS 7000 face masks, and composite cylinders). The product
includes a Dräger Sentinel TX Gauge.
2.2 Feature description
The carrying system has a carbon-composite backplate, with adjustable
shoulder straps and waist belt connected using quick release connectors.
The waist pad is connected at a exible joint to compensate for the twisting
and bending of the user.
All variants use the same high-performance rst-stage regulator (Fig 1,
Item 5). The regulator supplies medium-pressure breathing air through a
medium-pressure hose (6) and a quick coupling (2) to an attached lung
demand regulator. Incorporated in the rst-stage regulator is a RIC UAC
(rapid intervention crew universal air connection) (4), which is a male
coupling that allows emergency relling of the air cylinder while the wearer
is breathing from the apparatus.
The TX Gauge (Fig 2) is a mechanical pressure gauge (Bourdon tube
type) that has a photoluminescent gauge face with LED illumination, and
a whistle that sounds at the end-of-service-time (see Section 8 for the
end-of-service-time indicator (EOSTI) activation pressures). In addition to
the normal display of cylinder pressure, the TX Gauge provides battery
powered visual signals that indicate that the gauge is switched on (green
LED), low battery and hardware error alerts (amber LED), and low cylinder
pressure (red LED).
2.2.1 TX Gauge radio frequency link
The TX Gauge is equipped with radio frequency (RF) communication
circuitry that allows:
● Reading and reprogramming of the gauge
● Wireless transmission of data to compatible devices
● Pairing of the gauge with other compatible devices
Information that can be read from the TX Gauge includes device identity, a
record of events (datalog), the current values for congurable parameters
and the rmware version. Congurable parameters include intermediate
pressure warning activation pressures, gauge illumination duration, etc.
The parameters described in this document are the default for the device.
Reading and reprogramming of the gauge requires the Dräger PC Link
Module. Contact Dräger for details.
The TX Gauge has a short range RF wireless transmitter. This transmitter
can transmit data (such as switch on/off signals, pressure values, etc.) to
compatible devices (e.g. the FPS 7000 HUD (head-up display)) that are
within communication range. See the device Instructions for Use or contact
Dräger for details.
The TX Gauge may be paired with compatible removable integrated
Dräger Personal Alert Safety System (PASS) devices. Pairing ensures that
the PASS will only respond to signals transmitted by the paired TX Gauge,
and will ignore switch on/off signals transmitted from any other devices in
range. More than one PASS device may be paired with a single TX Gauge.
To check for paired devices within range, press and hold the gauge
illumination button for 10 seconds. See the PASS device Instructions for
Use or contact Dräger for details.
2.2.2 Compressed-air cylinders, lung demand regulators and face
masks
The PSS 5000 Series is compatible with composite material cylinders
of 30 to 60 minute capacity, and is available in 2216 psi or 4500 psi
versions. Full descriptions and user instructions are contained in separate
instructions supplied with the cylinder, face mask or lung demand regulator.
2.3 Intended use
When the PSS 5000 Series breathing apparatus is used with an approved
lung demand regulator, face mask and air cylinder, it provides a wearer
with respiratory protection for working in contaminated or oxygen-decient
conditions.
The cylinder, lung demand regulator, face mask and other accessories
used with this product must be certied Dräger components, assembled in
an approved conguration, otherwise the operation of the device may be
impaired. Contact Dräger for further information.
2.4 Approvals
The Dräger PSS 5000 Series is certied to 42 CFR Part 84 by NIOSH
and in certain combinations to provide respiratory protection from military
grade chemical, biological, radiological, and nuclear hazards (CBRN). The
series is also certied by SEI to meet the requirements of NFPA 1981:2013.
Approved PASS devices meet NFPA 1982:2013. The apparatus must only
be used in conjunction with compressed-air cylinders approved by NIOSH.
