Fire Alarm Door Magnets Wiring

Integrating fire alarm control using direct wiring.

Fire alarm door magnets wiring.

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. When power is restored the magnets will re. Making the magnetic field electrical current passes through the coil of the door holder. 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. It will interrupt the power if alarmed causing the doors to be released thus allowing the door closers to close the doors. We can use a relay to drop power to the electric lock or use an ip device that drops power using the network connection or add a power control box that drops power when the fire. A door holder prevents the door from closing because it hangs onto the door using magnetism.

Wire these holders directly into your fire alarm system. Depending on your fire alarm installation you may need to install a magnetic door holder at the location of each fire door. Mount the wall plate in an electrical outlet box or use a surface mount box sold separately. Power shall be controlled by the fire control system.

A magnetic door holder is a relatively simple device that when powered typically by 24vdc or 120vac will create a magnetic pull. All are reversible for right or left door swing directions. When activated by a fire alarm the magnet shuts off and releases the door.
