Well what is Fail secure how does it affect your use of a lock .Do people really know the difference Can they be used on a fire door or an exit door ? well the answer are not straight forward as each application can be different. That why its good to ask the experts. As not all release or locks will suit the required application. But at electric locking systems we are happy to advise on even the simple applications,
So fail secure really means when there no power to control the lock or no power to the lock. The lock will stay locked and will only be released by apply power again or by using a old fashion by using a key . But the access is still restricted.
