Fail Safe Door Hardware Definition

Fail safe means that a device will not endanger lives or property when it fails.

Fail safe door hardware definition.

Fail safe and fail secure are distinct concepts. So with a fail secure system the door remains locked unless it is manually overridden. Why build a delayed egress system. Fail secure locks are most often used for it rooms or other sensitive areas.

Locking device the locking device must be electrically locked and fail safe from the egress interior side. Fail safe locks are unlocked when the power goes out i e they require power to lock the door. Fail secure also called fail closed means that access or data will not fall into the wrong hands in a security failure. Also called fail locked or non fail safe.

Fail safe fail secure refers to the status of the secure side key side outside of the door. Should the power be interrupted or fail the door automatically unlocks or releases to let people out of the space. An electric strike replaces the regular strike for a lockset or panic hardware. Fail safe fail secure refers to the status of the secure side key side outside of the door.

Unlike fail safe fail secure means that if the power is interrupted or fails the door stays locked. 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. In this configuration applying electric current to the strike will cause it to unlock. 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.

Sometimes the approaches suggest opposite solutions. The most frequently used locking device in a component based delayed egress system is the electromagnetic lock. Most products provide free egress whether they are fail safe or fail secure. For a fail secure system the default state is locked or secured.
