Questions about this item

What does the 0.9 A starting current mean for my power supply?

The lock draws 0.9 A momentarily when it first energises, so a 12 V supply rated for at least 1 A is required to avoid voltage sag during that brief peak.

How do the NC and NO contacts affect access-control wiring?

NC keeps the circuit closed while locked and opens to release; NO does the opposite. Choose the mode that matches your controller’s expected state for a secure or fail-safe installation.

Will the 200 x 28 x 38 mm body fit my narrow stile door?

The mortise body measures 200 mm long, 28 mm wide and 38 mm deep. Verify your door stile is at least 28 mm wide and has 38 mm depth for the cut-out before ordering.
