Abstract (en)
[origin: EP1731770A2] An air reservoir primary valve (36) is fitted in a central housing. It is connected via only a single control line (37) to separate start-up buttons (18). The arrangement forms a series of manual start-up stations. On operating a smoke extraction button (18), the control line (37) is vented. Such venting causes changeover in position of the reservoir primary valve (36), from its initial position into a starting position.
