According to accident prevention regulations (BGV D4), cold store rooms with temperatures below minus 10°C and floor space from 20 m² must be equipped with an emergency alarm system that is independent of the general power supply and easily recognisable. By using a mushroom button with catch position, acknowledgement of a personal alarm is only possible following release of the mushroom button on site.
The requirements of the Swiss SUVA (Form No. 1864) are met in connection with this mushroom button. Since emergency alarm equipment is lifesaving equipment, special care must be taken during installation, commissioning and maintenance.
