Electric Strike - 3458

How it works

A Mortise lock includes a
latch and dead latch pin. When the lock is in the closed position, the latch is
extended (securing the door) and the dead latch pin is pushed in. This
internally pins the latch so that the door canЂt be opened by sliding a plastic
card in against the latch. The device operates the latch and dead latch pin as
follows: In the secure condition, the latch is captured in a cavity against the
latch plunger while the dead latch pin is pushed in by a flush finger plate.
The lock is released in two quick steps. First the finger plate draws back
which releases the dead latch pin and then the latch plunger and finger plate
move forward together which releases the door. When the door is re-closed, the
device automatically re-secures it including re-establishing full dead latch
security.

Adjustment to any mortise
lock

The chief problem with
procuring electric strikes to work with North American Mortise Locks is that
there is no standard or commonality among the lock manufacturers as to the
vertical position of the latch and dead latch pin in the standard ANSI 4 7/8
door preparation. This means that the electric strike must be specified and
purchased individually to suit the particular Lock model on the door. The
device is set by the installer in the field, just prior to installation, to
correspond to the Lock model. The latch cavity can be moved anywhere on the mortise
face with the finger plate occupying the space above and below the latch
cavity. The instructions show the correct setting for all North American mortise
lock models and adjustment is done quickly with a screw driver and allen wrench.
