Narrow Door Electric Bolt Mortise Lock

This electric bolt mortise lock is designed for narrow doors in access control systems. It operates on DC 12V power and fits aluminium, wooden, metal or security doors. The unit includes the lock body, a faceplate and mounting screws for installation.

Upgrade From Basic Latches

It replaces simple mechanical latches or older electric strikes that lack feedback signals or adjustable time delays. The jump is worth it when an access control system requires a fail-safe or fail-secure mode with positive and negative pole protection and surge absorption built in.

Suits Integrators Needing Feedback

Installers who need a feedback signal for monitoring lock status and a choice of NC or NO secure modes will find it suitable. Buyers who need a battery-powered or wireless lock, or who require a wider bolt for standard door profiles, should look at something else.

Questions about this item

What door thickness or stile width does the 200 mm by 28 mm by 38 mm mortise body require?

The lock body measures 200 mm long, 28 mm wide and 38 mm deep, so the door stile must accommodate at least a 28 mm wide by 38 mm deep pocket.

Which wires must be connected for the 12 V DC supply and the NC or NO feedback signal?

Connect DC 12 V to the power terminals; the lock draws 0.9 A at start-up and 0.09 A while holding. Wire the feedback circuit to the NC or NO contacts depending on the chosen secure mode.

How often should the bolt mechanism and mounting screws be inspected after installation?

Check the bolt throw, faceplate alignment and all supplied screws every six months; tighten any that have loosened and verify the delay setting remains at 0, 3 or 6 seconds.
