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 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, 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 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.!!123941235678910411ii153!

The t test must be conducted strictly in accordance with the requirements outlined in the OSHA Respiratory Protection Standard 29 CFR, Section 1910.134.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 eects 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 ow 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.Safety Warning: The remaining duration begins from the time of opening the cylinder valve and disconnecting the independent air supply. The time required to allow the wearer to escape to a safe area must be within the remaining air capacity (volume) of the cylinder taking into account the breathing rate of the wearer.ii!3
