Dorcas ADCN203+S electric strike, with mortice faceplate

Dorcas 12V Electric Strike, Rim or Mortice, Fail Locked ADCN203+S

What this electric strike is for

A door entry or access control system often needs to release a door that already has a mechanical latch. An electric strike does that by changing the frame side, so the latch itself stays as it is.

This one is from the Dorcas RIM SERIES, for doors with a rim nightlatch or suitable latch. It suits installers working on timber doors with low to medium traffic.

How does an electric strike work?

The strike sits in the frame where the latch engages. When it is powered, its jaw lets the latch pass, so the door can be pushed open.

  • Fail locked: the door stays locked when the power is off, and needs power to release. The access control system guide explains how this differs from fail safe.
  • Fail unlocked: the opposite type, in the same range as the 12V DC ADCN203-512+S.

Where to use it

This range suits inward opening timber door and frame applications. With the mortice faceplate it can also serve outward opening doors.

Check the IP rating and temperature range in the unit's documentation, and plan to keep it sheltered. A fail locked strike does not free the door when power is lost, so check any door on an escape route with whoever holds the building's fire strategy.

What the figures mean in practice

  • 12mm latch projection: this is the longest latch the strike takes. Measure the latch on site before ordering.

Installing it

  • Power duty: check the duty rating with the maker before leaving it powered for long periods. Where a door must be held released for long periods, the 12V DC ADCN203-412+S is continuously rated.
  • Check the current: confirm the draw on the fitted strike before relying on a shared supply.

Planning your system

The strike needs something to trigger it and something to power it. That usually means an exit button or door entry panel, plus a suitable access control power supply.

Other electric strikes cover other latch types and lock modes, and electric strike accessories cover fitting parts.
