How Do Magnetic Fire Doors Work

Making the magnetic field electrical current passes through the coil of the door holder.

How do magnetic fire doors work. The door holder is an electromagnet a door holder prevents the door from closing because it hangs onto the door using magnetism. Once a fire alarm occurs the fire alarm panel sends a signal to the control relay to activate. Worryingly the fire door inspection scheme fdis recently highlighted that three quarters of all fire doors inspected in 2019 were condemned as not fit for purpose. When power is applied to the door lock or door holder the electromagnet is turned on and keeps the door locked or the door held open.

Magnetic door locks use an electromagnetic force to stop doors from opening so they are ideal for security. Magnetic door locks and magnetic door holders work the same way. Hold open closers magnets fire life safety products provide a wide range of solutions. The two parts are installed on the frame and the door so that their magnetic sides are facing each other.

Not unlike what you learn about magnetics magnetic locks work by north and south end meeting and sealing but magnetic door locks use an electrical current to produce a stronger magnetic force. Hold the door open during normal hours of operation but will release when notified in an emergency situation. Saphirstein initially proposed to use a linear stack of door holders to work as an electromagnetic lock. If the door mag uses a separate power sourc.

The mounting plate can be installed in case your door frame or door doesn t allow direct mounting. Mag hold open devices are connected to the fire. Single or multi point hold open closers. Fire concerns by local authorities in locking the doors at the forum prompted management to find a locking solution that would be safe during a fire incident.

When energized the electromagnet will hold onto the metal plate to hold the door open. A small metal plate is attached to the door and is positioned to come in direct contact with the electromagnet. That much is. Also known as mag hold open devices electromagnetic door holders are available for floor or wall mounting.

If powered by the fire panel the panel can be programmed to shut off the power to the door mag when in the alarm condition. Utilize an electromechanical closer. If you own a commercial or non domestic property there are strict regulations and guidelines to follow ensuring the doors can withstand certain heats. The magnet can either be powered by the fire panel or a separate power source.
