5.1.1 Cutting the mortises
Referring to the dimension drawings in Section
3; mortises are cut into the door and door frame
suitable to fit the strike plate and lock. Wooden
doors and frames require full mortises where
metal doors and frames, being hollow, often
only require a single rectangle cut-out to
accommodate the lock face plate or strike plate.
For these installations the supplied fitting tabs
can be used to secure the lock and strike plate
in place.
The mortise behind the lock body needs to
have enough space to accommodate the
wire connections.
5.1.2 Wiring the lock
Wires are run from the power supply to the lock.
A hole needs to be drilled in the back of the
mortise to bring the wires out and a connection
can be made to the supplied wire loom which in
turn plugs into the lock. The jumper needs to be
positioned for fail safe / fail secure configuration
as per the instructions on the lock cover.
The Red, Black and Blue wires are essential
connections whilst the Violet and White are
optional. Detailed wiring instructions can be
found in Section 6.
5.1.3 Fitting the lock and strike plate
The lock is slid back into the mortise, making
sure that the wiring integrity is maintained and
secure in place with the supplied 10G self
tapping screws.
Before the strike plate is installed the fitting tabs
are secured in behind the cut-out using the
supplied M5 machine screws. The strike plate is
then placed into the cut out and the remaining
M5 screws are used to secure it.
