Satin Stainless Steel. The Union CE4F-E electromagnetic door closer is a dual-function solution that can be set to one of two modes: hold-open or free swing. When in hold-open mode, the CE4F-E allows people to walk through the doorway without opening the door, offering the ultimate barrier-free solution. This makes it ideal for hospitals, hotels, theatres and other high-traffic public areas. By removing the need for physical contact, it also reduces the spread of germs – a consideration that is increasingly in demand following the outbreak of Covid-19. Alternatively, in free-swing mode, the door operates as though no closer is fitted. This allows the door to swing freely with little force required to open it; suitable for the needs of residential bedroom doors in care homes, for example. Both modes provide assured fire safety, should an incident arise. The CE4F-E complies with the demands of BS EN 1155 by connecting to a building’s fire or smoke alarm system. In the event of a fire, power is cut to the unit, allowing it to automatically close and stop the spread of fire and smoke.
