gibby Posted February 25, 2008 Report Share Posted February 25, 2008 Can these be forced open without braking the magnet? Gibby Quote Link to comment Share on other sites More sharing options...
Big_Sam Posted February 25, 2008 Report Share Posted February 25, 2008 If its just magnetism holding it shut, then yes just force away and eventually you will break free from the field. Quote Link to comment Share on other sites More sharing options...
pin Posted February 25, 2008 Report Share Posted February 25, 2008 We use these at work, well, electromagnetic closure units on actuated doors. I have seen the mount for the magnet (either side) or the frame fail before the magnet releases. Where it's a single magnet closure with the fixing at the top of the door the danger is the door or frame will fail before the magnet.

AdamC Posted February 25, 2008 Report Share Posted February 25, 2008 We have these at work anf they can be forced without breaking them. They do come in different strengths, so as mentioned you may break a mouting bracket or the door before you gain access. Quote Link to comment Share on other sites More sharing options...
Big_Sam Posted February 25, 2008 Report Share Posted February 25, 2008 You could always cut the power to the magnet..... Quote Link to comment Share on other sites More sharing options...

I have been in sites where they are used I have tried to jemmy one with a crowbar. I was not stong enough to force the door. taz. Quote Link to comment Share on other sites More sharing options...
pin Posted February 25, 2008 Report Share Posted February 25, 2008 I've seen non-security ones before and they don't look up to much - depends on what they are installed to do I suppose! Quote Link to comment Share on other sites More sharing options...
ph5172 Posted February 25, 2008 Report Share Posted February 25, 2008 The power can be cut to the magnets but most have a fail safe lock also. The ones usually found on gates and doors are about the size of a large box of matches and can usually withstand a direct pull from a car or similar, they will also lock through hands and planks of wood and the like. The power cables are usually aromoured and contained within the door frame same with the control cable Quote Link to comment Share on other sites More sharing options...
pin Posted February 25, 2008 Report Share Posted February 25, 2008 In our application they are wired as you say, however the supply to them can't be cut as the the armour runs inside a central tube with a free floating outer. You could break in and then gas torch cut them but your torch would need to be some piece of kit to burn in a 100% haylon or argonite environment . If you get through that there is another supply to them from battery via an inverter which keeps them shut in mains fail or break in situations.
