Batteries are supplied with the equipment but are not fitted. Drger recommend that the batteries be removed when the system is not used for long periods as a small amount of discharge still occurs. The normal operating life of the batteries is dependent on usage time, frequency of alarms, backlight illumination and ambient temperature. The back-up battery will only supply power when the main battery is disconnected or discharged. When this occurs, the back-up battery will only supply power for HUD functions. 11 3 10 9 8 7 1 2 2 2199 1 3 2195 bar psi MPa 4 The Drger PSS 7000 is a compact and lightweight apparatus that provides the wearer with respiratory protection when working in contaminated or oxygen-deficient conditions. The system can be used as a self-contained system or with an independent air supply to increase effective operation time. The system is fully compatible with a wide range of compressed-air cylinders, face masks and lung demand regulators (LDRs). Preparation for Use Equipment configurations for non-CBRN use are detailed in a NIOSH Approval Table

(refer to instruction no. 3356261). Configurations for CBRN use are detailed later in this instruction (refer to CBRN Use). 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 flexible 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 the pressure module and a HUD battery located in the HUD. The system is switched on by a press button 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, first-stage, regulator (9) fitted 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 first-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 apparatus. A wireless HUD unit (refer to instruction no. 3356234) locates in the face mask and 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. Installing the Back-Up Battery Orientate the SCBA to access the battery compartment. Unscrew and remove the battery cap (1, Fig 2), using a suitable coin. Insert the battery, +ve terminal end first, into the battery compartment. Refit and secure the battery cap. Do not overtighten. Installing the Main Battery Orientate the SCBA to access the pressure module (1, Fig 3). Inspect the terminals on the battery and pressure module, and the sealing rim around the battery terminals (all must be clean and undamaged). Locate the two slots in the top of the battery pack (2) on the tabs in the battery housing. Firmly press the battery into position until an audible click is heard, to indicate a secure attachment. The Sentinel 7000 will emit a single tone and will commence the self-check sequence (refer to Sentinel 7000 Self Check). Press and hold the RH and LH buttons of the user interface until the display clears, then immediately release the buttons. ii

ii

A battery check is performed during the self-check sequence. If the battery voltage is below a preset voltage the backlight will illuminate; the low battery icon (Fig 4) will be displayed; the Sentinel 7000 will emit a series of tones for approximately four seconds; and then the display will switch off. When this occurs replace the battery. To remove the battery insert and press the two pronged key (supplied with the SCBA) into the two slots at the base of the battery. This will open the locking latch allowing the battery to be removed. Installing the Cylinder ii

(refer to Sentinel 7000 Self Check). Up to approximately 45 seconds after the start of the self check, all six HUD LEDs

(Fig 14) will flash twice to indicate that the Sentinel 7000 is communicating with the HUD. Depending on cylinder pressure, some of the line of four HUD LEDs (red/amber/

green/green) will flash (on for 15 seconds/off for 45 seconds). Close the cylinder valve and observe the user interface display. The pressure reading shall not decrease more than 200 psi in 1 minute. ii

If the SCBA fails this test, or an immediate leak is evident, do not continue with the check. Vent the pressure, switch off the system and contact Drger for repair. psi Cover the outlet of the LDR with the ball of the hand and press the front button (2, Carefully lift the ball of the hand to slowly vent the system observe the pressure Fig 13). displayed on the user interface. Note the pressures for the electronic EOST activation (indicated by an audible alarm tone; flashing red and blue LEDs on the user interface; flashing red LED on the HUD) and the mechanical whistle operation. Electronic and Mechanical activation does not need to be simultaneous but both must be within the acceptable range (refer to Technical Data EOST Alarms). Refer to the Service Manual if the pressures are outside the acceptable range. Allow the system to vent to zero pressure. The display will show zero pressure and all of the user interface LEDs (Fig 8) will flash at approximately one second intervals. The green LED indicates that the system is still in active mode. Press and hold the RH and LH buttons of the user interface until the display clears, then immediately release the buttons. The HUD red LED (Fig 14) will flash intermittently. After approximately 180 seconds all six HUD LEDs will flash twice to indicate that the unit has logged off from the Sentinel 7000. Press the reset button of the LDR to switch off the positive pressure. Check that the face mask port and the connector O-ring of the LDR are clean and undamaged. Align and push the LDR into face mask port until it latches in position. Check the attachment by attempting to pull the LDR away from the face mask. 1 Normal Operation

All safety information, including the preliminary safety details, must be read and understood before commencing any user task.

Q Use in conjunction with personal protective ensembles that provide appropriate levels of protection against dermal hazards. R Some CBRN agents may not present immediate effects from exposure, but can result in delayed impairment, illness or death. T Direct contact with CBRN agents requires proper handling of the SCBA after each use and between multiple entries during the same use. Decontamination and disposal procedures must be followed. If contaminated with liquid chemical warfare agents, dispose of the SCBA after decontamination. U The respirator should not be used beyond 6 hours after initial exposure to chemical warfare agents to avoid possibility of agent permeation. S Special or Critical Users Instructions Approved for use at temperatures above minus 25 degrees Fahrenheit (minus 31.7 degrees Centigrade). When used as a combination supplied-air respirator/self-contained breathing apparatus

(SAR/SCBA), not more than 20 per cent of the air supply can be used during entry. During supplied air use, the cylinder valve must remain closed. If the supplied air fails, open the cylinder valve and immediately proceed to fresh air. Supplied air source must meet the following criteria: pressure 87 125 psi, air flow rate at least 550 litres/minute. Important Note: If it is decided to exit the working area with the airline disconnected or, in an emergency, if the air supply fails, breathe normally and immediately proceed as follows:

Open the cylinder valve (counterclockwise) slowly, but fully and breathe normally. Disconnect the hose of the independent air supply from the male coupling of the airline hose connection. Breathe normally and immediately leave the hazardous area by the shortest and safest route.
