Descriere
The Pressure Watch has the same shut off function as an ordinary Emergency Shut-Off Valve Box. Behind the plexiglass you can find quick couplings and gauges. The quick couplings are used to connect spare cylinders with regulators and emergency supply hoses.
To inform the hospital staff regarding gas failures the Pressure Watch is equipped with sensors for one of the following alarm systems; 1) – pressure switches that you connect to Gas alarm C44, 2) – pressure transmitters that you connect to Gas alarm MC7701 or 3) – pressure transmitters 4-20 mA that you connect directly to the hospital central computer system.
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, fits between the beams in a CC-60 wall. The box is gas-tight which prevents gas accumulation inside the wall.
The product is CE-marked according to EN ISO 7396-1 and present SIS HB 370.
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.
