Many doors in office buildings incorporate swipe-cards for security which can conflict with evacuation. The acceptable solutions state that where electro-mechanical locks are present in the event of a power outage or door malfunction they are required to automatically switch to the unlocked position or be able to be easily opened without the need for a key or card etc.
There is no specific requirement to have the locks connected to the fire alarm system.
If the door lock mechanisms automatically unlock then all is fine and dandy. Evacuating people can easily pass through the door.
But if they are of the type that do not automatically unlock then there needs to be push-button over-ride that will unlock them, so that people can evacuate.
Is this really acceptable? It is OK for people to push a button (on a final exit door possibly) in order to leave?
