Electric Strikes provide remote release of a locked door. They allow the door to be opened without retracting the latchbolt. This occurs by the releasing of the electric strike lip (sometimes called a keeper or gate). When the door closes the beveled latchbolt rides over the lip and falls into the strike pocket.
Electric Strikes come in models for wood, aluminum or hollow metal door applications.
Electric Strikes are often used for "buzz in" type of systems. Electric strikes come in many varieties.
When you need that buzzing sound you may have heard when being buzzed into an office that's the sound of AC current going through the electric strike. If you need this sound as a signal to push on the door when unlocking the strike then choose an AC electric strike and an AC power source or transformer. If you do not want or need this buzzing sound then choose a DC power source or transformer. The DC strike is almost completely silent when it releases except for a slight click sound. On average a DC electric strike will last longer than an AC electric strike. If you want to use a DC electric strike or magnetic lock but still want a signaling sound then see the electronic buzzer we sell towards the bottom of this page. This tiny buzzer is connected in parallel between the power supply and the electric strike or magnetic lock and makes a buzzing type of sound when the lock releases.
