An electrical lock is typically activated from the secure side of the door, which is where security protocols are often most stringent. This means that individuals who are authorized to enter can trigger the lock mechanism from within a secure area, maintaining controlled access.

In practice, this often involves systems where a button or a card reader is situated on the secure side, allowing individuals inside the secured area to unlock the door without having to use a physical key or alternative control methods. This functionality is critical in locations such as offices, hospitals, or any other facility requiring both security and controlled entry.

The other options reflect different activation methods but do not pertain specifically to the primary use of electrical locks. While a manual key, remote control, or a timer might serve specific purposes in different types of locking mechanisms, the fundamental operation of an electrical lock emphasizing security and authorized access particularly highlights the significance of control from the secure side of the door.
