Installation
Step 3: Wire and Mount the Doorphone (cont’d)
4. Run standard 3-pair cable from the KSU to the Doorphone location. Use one pair
to connect the "KSU" terminals of the Doorphone to a vacant station port of the
KSU. The second pair can be used to connect an optional DOC, leaving an
available spare pair.
All Doorphone connections are polarity insensitive. Strip wires 6 mm ( 1/4")
before inserting them in the terminal block and tightening.
5. When the surface mount bracket is used, secure the wiring with a cable tie
through the round hole in the rear of the bracket as a strain relief. Fasten the
main housing assembly to the surface mount bracket or electrical box (customer
supplied), then fasten the faceplate to the main housing assembly.
