Mounting the Head Unit
Front Section
Back Section
Locate a surface adjacent to the opening side of the door, making sure that a person can stand directly in front of the
unit without obstruction. The unit should be positioned (where possible) on the wall so that the user’s forearm is
approximately 90 degrees to the wall during operation.
Prior to locating the back section of the head unit, double check that the cable passageway through the wall is
clear from obstruction (e.g. pipes, cables, etc.)
•
Locate the back section of the head unit (or use the template provided in Appendix I) using a spirit level to
ensure that the plate is level.
•
Inscribe the 4 screw holes and cable passageway (bottom right) with a pencil on the wall.
•
Drill and plug (where necessary) the wall where the 4 mounting screws are to be fixed.
•
Drill through the wall where you have marked the cable passageway, so that the cable can be passed directly
into the rear of the unit.
•
Mount the back plate of the head unit to the wall using screws appropriate for the surface being fastened to.

Mounting the Control Unit
The control unit can be placed above a false ceiling or high up out of general reach,
as no user interaction is necessary with this unit once installation is complete. Alternatively, all of the control
units can be located centrally in a communication closet.
The maximum distance between the head unit and the controller is 500 feet.
In order to make the process of mounting the control unit and connecting it to
the head unit as easy as possible, we recommend removing the 12v battery.
•
Locate a suitable flat surface on the inside of the protected door.
•
Ensure that the unit is level and inscribe the 4 screw holes with a pencil on the wall.
•
Drill and anchor the wall (where necessary) where the 4 mounting screws are to be fixed.
•
Mount the control unit to the wall using screws appropriate for the surface being fastened to.

Connecting the Head Unit to the Control Unit
•
Once the control unit and the back plate of the head unit are securely mounted, run a 4-pair (8 conductor) cable
between the head unit and control unit. A Belden 9504 or equivalent should be used.
•
The cable should leave the control unit via one of the push-out holes located on the bottom of the unit, running
neatly along the wall and into the hole drilled through the rear of the head unit. Leave approximately 8”
(200mm) of cable spare at each end to allow for stripping the wires and connection to the terminal blocks. We
also recommend allowing an extra 12” to 18” of cable to be left as a service loop behind the surface you are
mounting to.
•
The cable should be wired as shown below. The actual colors are not important but each pair of wires must be
connected as shown in the diagram.
•
Wire the head unit as shown below.
To simplify the wiring the 2-part connectors can be removed from the boards.
•
Strip approximately ¼” (6mm) of sheath from each cable and insert into terminal blocks, checking that all wires
are securely fastened.
•
Repeat the procedure at the control unit.

Connecting the Power Source to the Control Unit
Please ensure that you have a power outlet near the control unit
which will ONLY be used to supply power to the control unit.
ONLY the transformer supplied by Digitus should be used to power the control unit
(or an exact equivalent).
•
Strip approximately ¼” (6mm) of plastic sheath from each cable to the power supply and connect to the
appropriate terminal blocks, checking that all wires are securely fastened.
•
If you previously removed the battery (as recommended), please reinstall it and fasten securely.
•
Reconnect the battery as shown below.
