What happens when an electric bolt is activated?

1. The door locks permanently

2. The bolt retracts, allowing normal door operation

3. The power is turned off

4. The door automatically closes

The correct answer is: The bolt retracts, allowing normal door operation

When an electric bolt is activated, the mechanism is designed to retract, which then allows the door to operate normally. This means that when power is supplied to the electric bolt, it disengages from its position, enabling the door to be opened without obstruction. Electric bolts are commonly used in various locking systems, especially in access control scenarios, where they provide security while still allowing for convenience when authorized access is needed. The other choices do not accurately describe the function of an electric bolt. For instance, locking the door permanently would defeat the purpose of having an access-control system, which aims to allow for ease of entry and controlled security. Turning off the power would typically result in the bolt being locked, not retracted, while an automatic door closure does not inherently involve the operation of an electric bolt, as that would refer to a separate mechanism. Therefore, the correct understanding of the activation of an electric bolt is that it enables normal door operation by retracting.
