In this configuration the strike would remain locked in a power failure but typically the mechanical lock can still be used to open the door from the inside for egress from the secure side.
Fail safe door hardware definition.
Fail safe locks when looking at fail safe locks this means that it s default state is actually unlocked.
Unlike fail safe fail secure means that if the power is interrupted or fails the door stays locked.
Fail safe electric locking devices are used wherever doors must remain unlocked in the event of a fire or other life safety emergency.
For a fail secure system the default state is locked or secured.
The most frequently used locking device in a component based delayed egress system is the electromagnetic lock.
Fail safe fail secure refers to the status of the secure side key side outside of the door.
Why build a delayed egress system.
Most products provide free egress whether they are fail safe or fail secure.
To keep it locked during normal business operations power is applied.
In this configuration applying electric current to the strike will cause it to unlock.
Fail secure also called fail closed means that access or data will not fall into the wrong hands in a security failure.
Fail safe means that a device will not endanger lives or property when it fails.
An electric strike replaces the regular strike for a lockset or panic hardware.
So with a fail secure system the door remains locked unless it is manually overridden.
Fail safe locks are unlocked when the power goes out i e they require power to lock the door.
All electric strike and maglock locking devices use power to secure a door but what the lock does once the power goes out hence the term fail is what determines whether the lock is fail safe or fail secure.
Fail safe and fail secure are distinct concepts.
Also called fail locked or non fail safe.
Most products provide free egress whether they are fail safe or fail secure see below.
Locking device the locking device must be electrically locked and fail safe from the egress interior side.
Sometimes the approaches suggest opposite solutions.
