Magnamatic doors and why you need them

Let’s take a look at magnamatic – what it is, the industries that use it, how it works, and why it is a must-have for your doors. 

1. What Are Magnamatic Devices?

Magnamatic devices are specialised types of hardware that are installed inside doors to hold them open.

If an alarm or emergency is triggered, the device will automatically close the door. This will prevent a fire from spreading to other areas of the building and causing harm or damage to the building and/or its inhabitants.

2. Why Do You Need Magnamatic For Your Doors?

Magnamatic devices are often optimal for fire doors, smoke doors, and other “emergency” doors (e.g., doors in hospitals) that may need to stay open for various reasons (such as pedestrian traffic) but that still need to close in the event of a fire or emergency automatically.

According to the Building Code of Australia, all fire doors and smoke doors must be closed automatically if a fire alarm or emergency alarm sounds.

Magnamatic devices help you maintain this standard and ensure you remain compliant with BCA regulations.

3. How Does Magnamatic Work?

  • Magnamatic devices work by utilising electromagnetic systems and locks to hold the door open
  • When the electrical communication is “cut off” by an emergency alarm, the device relies on a spring mechanism attached to the door to close it automatically
  • The devices are usually mounted on the floor beneath the door or a wall behind the door; they can also be installed on the ceiling if required
  • The hardware will then be connected to a fire, smoke, or emergency alarm system, which will ‘trigger’ the holder to release the door if the alarm is activated
  • The door can also be released manually by simply installing a switch or button adjacent to the door


4. Who Uses Magnamatic Devices?

Magnamatic door holding devices are suitable for any operation that requires flexibility in the use of their doors. Still, they also require secure protection if a fire or similar emergency occurs.

Some common types of businesses and buildings that use these kinds of door holders include:

  • Hospitals and medical facilities
  • Schools and educational institutions
  • Cinemas and theatres
  • Corporate/office buildings
  • Manufacturing plants
  • Scientific and medical laboratories

5. Do My Magnamatic Devices Need To Be Fire Rated?

If you are installing these devices onto a fire door, smoke door, or similar, then yes – the devices must be fire-rated too, since they are considered fire door hardware and will operate as part of the entire door.

6. Further Tips On Choosing Magnamatic

If you are purchasing magnamatic door holders for your fire doors or other emergency doors, you’ll need to ensure that:

  • They can provide the right holding power and voltage for the size and weight of the door you are planning to install
  • The entire device, including wall brackets, complies with the BCA hardware standards for fire doors and has a fire rating that matches the rating of the doors you have chosen
  • You may also want to choose a device that utilises minimal power supplies, which will assist in keeping energy costs down for the building
