Page 9: Backplate Assembly
Backplate assembly General The height adjustable, and articulating backplate assembly, provides the wearer maximum comfort and ease of use, resulting in reduced wearer fatigue. The backplate assembly consists of three elements: 1. The adjustable shoulder yoke. 2. The backplate. 3. The waist belt pivot slide assembly. Each of the elements is manufactured from a moulded carbon composite material, providing an anti-static, lightweight and durable system.
Page 10: Harness And Cylinder Strap Assembly
Adjustment 3.14 Three pre-set height settings are available to suit the body length of the individual wearer (‘S’ - short, ‘M’ - medium, ‘L’ - long), and these associated letters are embossed along the guide arms of the shoulder yoke. Short Medium Long...
Page 11: Telemetry Module
The material of the hose retaining flaps is a double coated Neoprene Polyester plus a ‘Scotchlite’ reflective outer printed with a photo luminescent pattern and a blue Dräger logo. The cylinder strap is fitted to a unique ‘Camlock’ buckle that ensures that the cylinder is securely clamped to the backplate.
Page 12 LFB image 248635 LFB image 1136764 The BA set must be shut down and the Bodyguard switched off when connected to the charging point. This ensures that the BA set is not searching for the ECB which can overrun the charging supply.

Page 14 The standard size combination of face mask and inner mask fitted to the PSS 7000 BA set is a medium mask ‘M’ with a size ‘2’ inner mask – ‘M 2’. If a seal cannot be achieved using this combination of face mask and inner mask, the wearer (following a face fit arranged through OSG) will be given either the S (small), M (medium) or L (large) face mask and 1, 2 or 3 inner mask combination as appropriate.

come into contact with the face mask double reflex seal, in a clean shaven condition and free from beard, stubble and sideburn hair. 7.10 The HSE advise, and past fire brigade experience shows, that sweating can cause face masks to slip.
Page 16: Pneumatic System
As the diaphragm deflects, it then presses against the main hinged lever of the balanced piston unit resulting in the release of the positive pressure ‘off’ mechanism. Increasing deflection of the diaphragm, during inhalation, pivots the cam of the main lever against the secondary lever.
Page 17: Second Person Connection
Two of the hoses that connect to these ports are looped through the central hole in the backplate and located into the respective channel in the adjustable shoulder yoke, from which they are directed and secured to the shoulder pads. The hose to the second person connection is run up the left hand side of the backplate.
Page 18 10.2 The hose to second person QRC is 900 mm long and when charged contains medium pressure air (between 6 and 9 bar) from the reducer to the QRC. 10.3 Once the second person connection has been made the second person hose can be released from its retaining clips.

• Button activated manual distress signal unit (DSU). • A ‘backlight’ – illuminating the display. Pressure transmitter module 11.5 Pressure connection – pressure sensor (see paragraph 9.14) for connection to the high pressure outlet port of the first stage pressure reducer via a high pressure connection hose (see image 245556).
Page 21 Motion sensor 12.8 With the Bodyguard key removed, if no movement is detected for approximately 30 seconds, then a repeating audible ‘pre-alarm’ sound is emitted. If movement is then detected within a further 15 seconds of commencement of the ‘pre-alarm’ – the alarm is automatically cancelled. 12.9 The pre-alarm can only be switched 'off' by the movement of the Bodyguard display unit or Bodyguard key insertion.
Page 22: Bodyguard Electronic Monitoring Unit Self-Check
Low pressure warning 12.20 The electronic low pressure warning will sound at 84 bar. This indicates the start of the 12 minute safety margin for SDBA and 18 minute safety margin for EDBA. 12.21 The pneumatic low pressure warning whistle will sound at 74 bar (+/- 5 bar). This indicates that 10 minutes of the safety margin remains for SDBA and 16 minutes remain for EDBA.

13.10 The display will then quickly change to ‘non-operational mode’ icon (see image right). 13.11 The green LED continuously flashes at approximately one second intervals. Note: the display of an ‘X’ or ‘telemetry fault code’ icon alerts the user that the Bodyguard 7000 has failed the ‘self-check’...
Page 24 14.11 A final outer layer of laminating resin is applied to the external surface of the cylinder to provide a smooth easily cleaned surface. 14.12 This outer resin layer is tough and wear resistant to further enhance the durability of the composite cylinder in everyday use.
Page 25 14.14 The basic features of the standard valves are; (a) Brass/chrome plated valve body. (b) Flame retardant cylinder hand wheel - (incorporating ratchet mechanism). (c) Sintered filter element. Ratchet hand wheel 14.15 The valve is fitted with a spring loaded ratchet hand wheel mechanism and is opened anti clockwise;...
Page 26 14.30 As the lower spindle rotates it moves down the square drive of the spindle and towards the outlet sealing rim in the valve body. 14.31 When the sealing face of the lower spindle contacts the sealing rim this closes the valve preventing high pressure air discharging from the cylinder.
Page 27 14.44 Do not remove stick-on labels. 14.45 Cylinders should be carried using the method shown below. Do not lift the cylinder using the cylinder hand wheel – 300 bar cylinder outlets have an increased jet reaction from inadvertent release of stored pressure which could lead to injury.

Page 28 14.50 Feed this loop back through the mechanism thereby loosening the strap around the cylinder cover to help facilitate the cylinder’s removal (see image 1136785 right). LFB image 1136785 LFB image 1136789 LFB image 1136786 LFB image 1136787 LFB image 1136788 14.51 Unscrew the cylinder connection (anti-clockwise) and carefully remove the cylinder from the BA set by drawing it away from the reducer.
Page 29 14.57 Ensure cylinder retaining strap is fully extended so there will be clear space around the cylinder cover for ease of movement. 14.58 Insert cylinder from opposite end to reducer/cylinder connection (this is to ensure that no fibres are deposited in the connection if the cover were to pass over it).
Page 30 14.63 Continue feeding the excess through the securing mechanism until the cylinder retaining strap just grips the cylinder cover (see image 684787 right). LFB image 684787 14.64 Operate the securing mechanism by pulling the cam over the cylinder and using the ‘Velcro’ on the underside of the excess strap then secure it, ensuring it functions correctly (see image 684785 right).
Page 31 14.69 Place the ‘D’ ring over the male part of the press stud. LFB image 684777 14.70 Place two fingers under the shoulder strap press stud and use your thumb on top to create a ‘depression’ or use work surface. LFB image 684776 14.71 Offer-up the female part of the press-stud to the male part on the shoulder strap of the BA set ensuring that the...
Page 32: Sdba Set - Lifting And Carrying Instructions
14.73 After connections are complete – test the press-stud is secure by placing two fingers under the flap of the ‘Dräger’ motif and pull gently. 14.74 Repeat this process for the other anti-entanglement strap. LFB image 684780 14.75 The cylinder cover with anti-entanglement fixture is now complete.
Page 33 Description 16.6 The cylinders fitted to the EDBA cylinder pack are constructed in the same way as the SDBA cylinder (see 14.6 – 14.12). Two cylinders are permanently coupled together to form a ‘cylinder pack’ (see image 178633 right). 16.7 The two compressed air cylinders are aligned and secured in tandem onto a central support strut by a pair of stainless steel straps.
Page 34 16.19 Twin cylinders should be carried vertically ensuring that a firm grip is taken around the cylinder handle as shown. Do not lift the cylinder using the cylinder hand wheel – 300 bar cylinder outlets have increased jet reaction from inadvertent release of stored pressure which could lead to injury (see images 1136767 and 1136766 right).
Page 35 16.28 Insert the twin cylinder pack into the cylinder cover ensuring a snug fit. LFB image 684809 16.29 Pass each strap under the twin cylinder securing bracket (as this prevents the straps from catching on the securing mechanism of the EDBA set) and fasten to the Velcro strip on the opposite side of the cover (see image number 684807 right).
Page 36: Edba Set - Lifting And Carrying Instructions
16.33 Press and hold the backplate down onto the top cylinder retaining bracket to open the spring plate and slide the backplate away from the handle of the twin cylinder pack until a click is heard (see image 250378 right). 16.34 Check that the twin cylinder pack is secure.
