Inward opened, conventional door (Knox 1B, Knox 1BX)
The instructions for an inward (toward hazardous area) opened door use the same illustrations as for an outward
opened door. The main difference between the two is that a lock for an inward opened door is mounted on the
inside of the door, towards the hazardous area, which is why the handles are different from Knox 1A/-1Ax locks.
1 ) Component overview.
2 ) Attach and fasten the outer(silver coloured) handle on the back of the door part. Prepare the door part for
mounting on ABB Jokab Safety Quick-Guard system by lightly attaching the mounting nut and screw according
to figure 2.
3 ) The type of door determines what step to take.
a. If the door surface is completely covered, a hole needs to be drilled for the handle. The centre of the hole
should be 25-30 mm from the Quick-Guard aluminium profile (or ~70 mm from the edge of the door). The
diameter of the hole should be 45-60 mm.
b. If Knox is to be mounted on a mesh door, an extra PC plate (article number 2TLA020106R0000) can be
placed on the mesh to prevent the door from being opened from the outside (using the escape release) or
reset from the inside (e.g. by using a screwdriver to push the handle, refer to risk analysis to determine
necessity). It might be necessary to cut away a small piece of the mesh to get the handle through, see
figure 3b.
4 ) Pass the outer(silver coloured) handle through the hole from the inside to the front of the door. Fit the
mounting nut to the Quick-Guard profile. Fasten the mounting screws lightly to still be able to adjust position.
5 ) Perform step X) if necessary. Mount the Knox frame part according to figure 5. Make sure that the M12-
connector is facing upwards.
6 ) Adjust horizontal and vertical position. Make sure the guiding pins on the frame part are centred in the locating
holes on the door part. Fasten the mounting screws with the tightening torque according to figure 6. To comply
with safety standard EN 1088 the socket head cap must be drilled if a fitting hex key may be accessible to
X) At delivery, the frame part is ready for use with a door part for an outward opened door with hinges to the right,
or an inward opened door with hinges to the left. If necessary, the frame part can be adjusted to fit the opposite
type of door, i.e. an outward opened door with hinges to the left or an inward opened door with hinges to the
right. To achieve this, unscrew the upper guiding pin and screw it back in the threaded hole on the opposite
side. The lower guiding pin is pushed to the opposite side until the guiding pins are of equal length.
