Mortise Night Latch Locks and electric strikes

If the lock is fitted into the door, it is known as a Mortise Lock.

In order to electrically release this type of lock you will require a mortise release. This replaces the existing strike box (which is fitted to the frame).

The most popular type of mortise lock for door entry and access control us is a LATCH MORTISE lock.

Note:
Although it is possible to release a dead lock, it it often not desirable to do so.

Next, you need to decide on a suitable electric strike (lock release).

Often this budget type of electric strike is used for door entry intercom systems and are 12V AC operation. This means they require 12V AC supply to operate the coil, which releases the keeper.

These are budget strikes and offer low security.

If you want a better quality strike to work with a mortise latch lock you could opt for either the Gianni ER310, the Alpro EL901 or one of the many Trimec electric strikes.

These electric strikes

• require DC power
• are stronger than the budget strikes.
• fail open and fail secure (changed by making a simple adjustment to the electric release).
• come with long (for timber from) and short faceple (for metal frame)
