3 Description

The Dräger PSS 7000 Series is a 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 Dräger compressed air cylinders and the FPS® 7000 face mask. The product includes the following electronic monitoring systems:

● A Dräger Sentinel 7000 electronic monitoring system, with integral PASS (personal alert safety system).

● A Dräger FPS® 7000 wireless HUD (head-up display) unit.

3.1 Feature description

The carrying system has a carbon-composite backplate, with adjustable shoulder harness and waist belt connected using quick release connectors. The height of the backplate can be adjusted to one of three preset heights to suit the body length of the wearer (short (S), medium (M) and long (L)). The waist pad is connected at a flexible joint to compensate for the twisting and bending of the user.

All variants use the same first-stage regulator (Fig A, Item 5) fitted with a whistle that sounds at the end-of-service time (see Section 10 for the endof-service time indicator (EOSTI) activation pressures). The regulator supplies medium-pressure breathing air through a medium-pressure hose (Fig A, Item 6) and a quick coupling (Fig A, Item 2) to an attached lung demand valve (second-stage regulator). Incorporated in the firststage regulator is a RIC UAC (rapid intervention crew universal air connection) (Fig A, Item 4), which is a male coupling that allows emergency refilling of the compressed air cylinder while wearer is breathing from the apparatus.

The electronic system is the Sentinel 7000, which is a multi-function system that continuously monitors the breathing apparatus status, including cylinder pressure, movement of the wearer, and battery condition. It provides visual indications of system status and audible and visual alarms in warning conditions. The user interface has an electronic LCD (liquid crystal display) screen (Fig B, Item 1), left (L) and right (R) operating buttons, a manual alarm button (Fig B, Item 2), an LED

panel (Fig B, Item 3), and an internal alarm sounder. A backlight illuminates the user interface display when required. An additional alarm sounder (Fig A, Item 1), referred to as the “second sounder”, is mounted on the backplate, with warning activation LEDs top and bottom. The second sounder operates only during PASS alarms.

Personal identity information (e.g. user name, brigade name, station number) can be stored in the user interface memory of the Sentinel 7000.

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 switchon, 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 2125 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

The PSS 7000 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 valve.
