Electric Releases

Electric strikes work in conjunction with latches on doors and take the place of the traditional strike plate that is used with a latch.

The "jaw" of the strike is controlled by a solenoid which allows the door to be pushed open on release. On closing, the latchbolt will spring back into the jaw of the lock and remain in the locked position until its next operation.

Electric strikes are popular as they are small and discreet, they can be fitted into both metal and timber frames, they can work with existing door locks and they offer a strong holding force on the door.

Strikes are available in both fail locked and fail unlocked versions but care must be taken when a strike is connected to a fire alarm system as side pressure on the lock will temporarily bind its mechanism. Please ensure you always ask the advice of LOCK-TEC when selecting a locking solution for any application.

When choosing an electric release, it is important to consider how you want the lock to operate electrically, this can be important if the lock is being installed on an emergency escape route or being linked to a fire alarm. Locks are generally known as either "Fail Locked" or "Fail Unlocked" and their particular operations are detailed below -

Fail Locked - When the electric lock has no power to it the door is locked, power is then applied to release the door. Generally with a fail locked electric lock the inside of the door would have some form of lever to exit the door.

Fail Unlocked - When the electric lock has no power to it the door is open, power is then applied to the to lock the the door. Generally, a fail unlocked device is used in conjunction with a fire alarm system and the door would have either a lever or an exit button/break glass unit to exit the door.
