The DH-90 is an aesthetically pleasing, wall-mountable, round door holder magnet with a holding force of 280 kg, whose voltage requirement is adjustable.
Door holding magnets are designed to keep fire compartment doors open until a signal is received. In the event of a fire alarm, the power supply to the magnet is interrupted, allowing the door to close.
Their easy installation and wiring ensure quick commissioning, and most models are equipped with an emergency release button to allow the door to be released without control. They are ideal for fire-rated doors.
