medical central gas supply system edition 1/2013 The Pressure Watch is monitoring and supervising the gas pressure in a clearly stated part of the Hospital Central Gas Supply System. It is fitted with quick couplings for emergency supply, gauges and pressure sensors. To inform the hospital staff regarding gas failures the Pressure Watch is equipped with sensors for one of the following alarm systems: 1. 2. 3. Pressure switches - Gas alarm C44 Pressure transmitters 0-50 mV - Gas alarm MC7701 Pressure transmitters 4-20 mA - hospital central computer system. Alarm system 1 is the most commonly used. The Pressure Watch is delivered with 300 mm connection tubes and each box has been test pressurized and controlled for tightness. The Pressure Watch has large ergonomical handles. If mounted in a recessed way, the emergency shut-off valve box fits walls with 70 mm beam. With a 90 mm beam there is extra space (23,5 mm) behind the valve box usable for e.g. fire isolation. All models, also with four or five gases, fit between the beams in a CC-60 wall. The box is gas-tight which prevents gas accumulation inside the wall. It is important that the boxes are placed so that they are easily available for authorized personnel. The front door shall be sealed. In order to avoid mistakes the boxes shall be clearly and distinctly marked with gas sort. A sign showing which section the box serves must be placed in its immediate vicinity. The valves are open when the handles are in vertical position in line with the printed marking on the plate. To close the valves you turn the handle 90 degrees clockwise.
