EP 301 Cylinder Electric Rim Lock

The EP-301 Electric Rim Lock for Video Door Phones is an electric cylinder rim lock built to be released from a video door phone or intercom handset, rather than opened by hand at the door.

How it works

When a visitor is let in via the handset, the EP-301 releases electrically. It's a rim lock, meaning it's surface-mounted to the door frame rather than set into the door edge — worth knowing if you're planning a retrofit and want to avoid cutting into the door itself.

Why the cylinder matters

The EP-301 keeps a mechanical cylinder alongside the electric release. That means the door can still be opened with a physical key, independently of the video door phone or intercom — useful if the entry system loses power or you simply want a manual override available.

Checking it fits your setup

Before ordering, confirm your video door phone or intercom handset is the part that triggers the release — the EP-301 itself is the lock, not the entry panel or handset. If you're replacing an existing rim lock, check your door frame suits surface mounting rather than a mortice lock, since the two aren't interchangeable without adjusting the frame.
