Magnetic door holder fire alarm systems wiring diagram.

Master wiring diagram for 4 wire class a system with alarm panel monitoring. On the fire alarm side you would need a control relay to intercept a switch leg of power to the door holder circuit as well as an initiating device such as a smoke detector to activate the relay. These fire rated door holders have an energized coil which creates a magnet strong enough to hold the self closing fire rated doors in the open position. The activating input sw1.

The alarm circuit monitors if smoke is detected. Depending on your fire alarm installation you may need to install a magnetic door holder at the location of each fire door. When the fire alarm system detects smoke the current to the door holder turns off allowing the door to close. End of line eol resistor determined and supplied by others.

Door release supply fire control panel sounder circuit door release magnets sounders end of line resistor output sw1 sw2 a a a mains fuse block note the wiring to sw1 from the fire control panel sounder circuit should be as shown to include full monitoring if spurred off the wiring will not be monitored. When power is restored the magnets will re energize permitting the doors to be manually returned to their held open position. These door holder releases have a holding force of approximately 25 lbf 111n. The dorgards are great by the way but if the spec is magnetic door retainers they may want them as opposed to dorgards but if its high end property which a flat worth 3 5 mill is id expect a proper fire alarm in tbh a 2 zone panel is cheap enough and will give you the felxibility you need and give you extra income on repairs and servicing.

The door holder is an electromagnet a door holder prevents the door from closing because it hangs onto the door using magnetism. A wiring diagram is a streamlined conventional pictorial depiction of an electrical circuit. Terminal numbers shown correspond to position numbers of terminal strips on. That much is.

Collection of magnetic door lock wiring diagram. A magnetic door holder is a relatively simple device that when powered typically by 24vdc or 120vac will create a magnetic pull. The detector trouble circuit monitors if power is lost to the detector. 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.

Both door holders are fitted with an integral manual release button allowing the door to be closed without operating the fire alarm. When de energized by a relay controlled by the fire alarm system or other switch the door is released to a closed position checking the spread of smoke and flames. Both versions are supplied with a door mounting keeper plate. Shall be controlled by the fire control system.

It shows the components of the circuit as simplified shapes and also the power as well as signal connections in between the gadgets. Making the magnetic field electrical current passes through the coil of the door holder.
