Electric Locks for fire doors
In the UK we need to keep fire exits clear at all times also they need to un-lock at the push of a panic bar, ideally a single point of operation is required in which to operated the lock and get out.
Fire doors should open outward so the door will stay open as the flow of people leave the building.
In some cases, we need to secure these doors far better at night and depending on the building in the day time as well. Having a panic bar on the door may let people open the door and let anyone into the building which may compromise the security of the building.
Assuming you have this problem with your building what options are available to you that can keep the door secure but at the same time accessible in the event of an emergency.
Two electronic units are normally used to help with the problems above, one are magnetic locks and the other is solenoid bolts.
Magnetic locks can fit in the head of the door and keep the door closed with magnetic force. very simple and easy to fit and operate, can be connected to a fire alarm system so in the event of the alarm activating the magnet will fail safe and the door can be opened via the standard procedures in the vent of an emergency. in most cases this works well, but they do have down sides, one of these is that the door is only secured at the head of the door and can create a week spot in the door by allowing it to be twisted.

One other device that is gaining ground is the Fire Solenoid bolt. These can be fitted to fire doors and in my opinion are far more secure than a magnetic lock, the reason for this is projecting a secure bolt into the frame can hold the door far more securely than a magnetic lock.
BUT and a big but, DONT use any standard solenoid bolt on a fire escape door. the basic principle of these standard bolts, is that when power fails the bolt under a spring will recede into the fitting, which is what we want, however, any side load on the bolt by swelling of the door, or people trying to open the door the chances are the bolt will not spring back and the door will remain secure at the very time that you don’t want it to be. It is very important to use solenoid bolts that are designed for fire doors.
Locksonline is teaming up with some European companies to provide our own unique products that will help you in these situations.
For starters check out our fire lock that is designed to accept high side loads without failing in the event of an emergency. click “LocksOnline Fire Lock’
This lock can withstand up to 100 Kg of side load which is ideal for fire doors. Always make sure, however, that there are safety factors built in to ensure that the lock will fail in the event of an emergency, by override buttons and interfacing with Fire systems. Also ensure it is tested regularly
