CONNECTING AN INTERCOM (OPTIONAL)
There are many different types of intercoms available on the market today.
The wiring of these intercoms can vary in some ways, but the general wiring is the same. The three
main types of intercom are as follows:-
(i) 220 volt. This type normally plugs into the house mains, (220 volt supply) and then four wires are run
from the handset (inside the house) to the gate station (outside at the gate) and the motor (trigger).
(ii) 12 volt. This type normally gets its power from the motor (12 v/dc). This means that a minimum of
six wires are needed to run from the handset. Two wires to the gate station and four wires to the motor.
(iii) 6 volt. This type is battery operated, normally using 4 AAA type batteries for power. Only four wires
are needed to run from the handset. Two wires to the gate station and two wires to the motor (trigger)
The mounting of the intercom is the same with each type. The handset is placed inside the house /
office and the gate station is placed at the point of entry, this is normally the gate. The gate station is
normally mounted by means of a “gooseneck”
It is important to note that the communication cable MUST be run in a conduit
DO NOT run communication cable in the same conduit as any 220 v cable.
