Fire Alarm Door Magnets Wiring

All are reversible for right or left door swing directions.

Fire alarm door magnets wiring.

For use with doors that already have a closer these holders keep doors open with an electromagnet. A door holder prevents the door from closing because it hangs onto the door using magnetism. Integrating fire alarm control using direct wiring. Mount the wall plate in an electrical outlet box or use a surface mount box sold separately.

When the fire alarm system detects smoke the current to the door holder turns off allowing the door to close. Depending on your fire alarm installation you may need to install a magnetic door holder at the location of each fire door. Making the magnetic field electrical current passes through the coil of the door holder. 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. The door access control reader and the electric lock can be wired to the fire alarm in a number of different ways. Wire these holders directly into your fire alarm system. When activated by a fire alarm the magnet shuts off and releases the door.

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. 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.
