While more of a physical trait than an electrical, all electrical locks and Strikes have a fail safe or fail secure designation.
The rule for determining whether a unit is fail safe (called reverse action by some manufacturers) or fail secure (called non fail safe by some manufacturers) is simple. What is the condition of the electric strike or lock without power?
A fail safe unit without power is unlocked.
A fail secure unit without power is locked.
Applications
The most common function by far is the fail secure unit. Most applications require that the door be locked should there be a power failure. In most instances these units can be intermittent duty because they are only powered when the door needs to be open
Fail safe, on the other hand, should be used where there is a need to unlock a door should power fail. The most common use is for areas or doors that must become unlocked in a fire situation. The locks are tied into the fire system. When the fire system goes in to the alarm mode, the relay that the unit is tied into cuts off all power to the strike or lock, allowing the door to open. The fail safe lock generally is continuous duty because they are powered up for long periods of time to keep doors locked.
