Posted By Jenny R Harris Has anyone come across a design of security door lock that releases when the fire alarm isactivated but guards against unauthorised over-ride. We have fire exits with key pads fitted. These are linked to, and deactivate, when the alarm detection system is activated and hence the door can be opened instantly, there is also an over-ride break glass. The problem is the over-ride has to be placed within a certain distance from the floor (DDA compliant?) and the dementia patients see ' Break Here for emergency exit' and do exactly that... going off on a wander. I am sure there must be a simple answer to this... but it deludes me. Would be most grateful if anyone who has faced a similar problem could respond.

Posted By J Knight OK, my lats word; embarrassingly I've just read all your thread again and realise what it is you're actually asking. The short answer is no I haven't, John

Posted By Bob Thompson CMIOSH the main problem is one of detection and locking doors in itself is not always the only solution. we use a system called wanderguard, which in effect is a type of tagging for the want of a better word. this system enables you to be alerted that a person has left the building and also lets you know the last known location. Hope this helps
