Retainer DH series

Magnetic retainers are a fire control measure and vitally important. They are used as fixed installations on fire doors and keep these doors open until a fire alarm exists. The doors are closed by automatic or manual activation to prevent the spread of fire and smoke throughout the building. The magnetic retainers are inspected by the Applus+ certification company in accordance with current construction regulations and approved according to the European standard EN1155 and EN14637. Maximum adaptability The new modular design is able to adapt to different types of doors, making it more versatile and flexible in any situation. They are also very easy to install, adjust and customize, saving time and reducing installation costs. Also, as it fits the door better, the risk of damage to the installation is reduced. Pushbutton for manual release All OPENERS & CLOSERS models incorporate a push button for manual door release that allows the door to close without the need for a fire or emergency alarm. Unlike other push buttons, at OPENERS & CLOSERS we guarantee 25,000 cycles functionality to keep you always safe in case of fire. The push button should be located in the center or as far outside as possible so that there is easy access to the electrical disarming. 3 connection openings For Surface mount installations, 3 openings of 20.5 mm have been created in order to correctly fit the conduit tubes of the electrical wiring. The finish of the installation is improved and they are protected from any manipulation.
