How many configurations are there for an electric strike?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

Electric strikes come in two common configurations defined by what happens when power is removed. In one setup, removing power releases the door, so the door unlocks (fail-safe). In the other, removing power keeps the door locked and you need power to unlock (fail-secure). Since the standard choices boil down to these two behaviors, there are two configurations. Other counts would imply additional distinct behaviors that aren’t part of the typical two-state options, though you can choose a model to meet safety or security needs.
