Fire Alarm Door Magnets Wiring

Wire these holders directly into your fire alarm system.

Fire alarm door magnets wiring.

Door releases will be energized with the voltage shown at right in the hardware set for this opening. All are reversible for right or left door swing directions. A door holder prevents the door from closing because it hangs onto the door using magnetism. Making the magnetic field electrical current passes through the coil of the door holder.

When power is restored the magnets will re. When activated by a fire alarm the magnet shuts off and releases the door. Depending on your fire alarm installation you may need to install a magnetic door holder at the location of each fire door. The door access control reader and the electric lock can be wired to the fire alarm in a number of different ways.

For use with doors that already have a closer these holders keep doors open with an electromagnet. Wiring them depends on what smoke heat alarms you have in if you have a fire panel unlikely in domestic unless landlord flats then use the open on alarm volts free relays to drop power to magnets if you have mains smoke heat detectors then they need to have an auxillary volts free output so you can use it again to drop power from magnets on alarm. It will interrupt the power if alarmed causing the doors to be released thus allowing the door closers to close the doors. The magnetic portion of this device is installed on the wall that meets the open fire door now to tie this whole concept together you will.

Power shall be controlled by the fire control system. Integrating fire alarm control using direct wiring. A magnetic door holder is a relatively simple device that when powered typically by 24vdc or 120vac will create a magnetic pull.
