These robust encapsulated electromagnetic door holders have a door holding force of 120kg (1200N)
I am surprised they are so low - so if you could get any purchase for a lever or a couple of big blokes you could pop it. I presume they also have a remote release, other than the red button, otherwise what would be the point? A decent bolt or bar would be far more secure.
Didn't that Greek chap, which legend has it had a penchant for baths and running down the street naked, say something along the lines of "Give me a place to stand and with a lever I will move the whole world"
Dearest magnetologists,As a sheepy I of course luff magnets !..From the moment I awake all I ever do is think about magents and magnet related joyness !...yep magnets are just like...well great !!
There was keyed magnetic lock in a building where I used to work. It seemed pretty stout. I was told that it had an IR sensor on the inside, so I always wondered if the mechanism could be defeated by pouring a bucket of warm water under the door, but never tested it.Remember, you can have the best retina scanners or keycard access... that is only as good as the weakest link in the entire system.
