How to Install a Home Intercom System
You only need a little carpentry and wiring knowledge to get your system together. But remember with the latest in technology, the wireless intercom system will get you out of the need to wire anything so choose well.
The first step: Check the master station box or covering to conclude how much space you would need through a wall. The manufacturers will normally provide a projection with holes for lifting the screws to install the master station within a wall. When you have checked the measurements needed, find the studs inside the wall, and make sure the hole you drill is between the studs. Using a pencil, draw the shape of the master station hole on a comfortable location on the wall. About 3/8 of an inch holes in four end points where you had penciled out on the wall are needed. Cut out the hole for the master station using a saber saw. Put the box in its location, and smooth our the ends of the hole if needed. Take out the box and leave aside until ready to mount.
Next, cut holes for the substation locations on the walls. Check to make sure they fit in the hole, and then set aside for later use.
In step three, check the wiring diagram that is included with your purchase. Only the master station installation should have connection to the home’s electrical system. The substations are linked to the master station by way of cables which come with the purchase. If you don’t have the cables, you can always go to your local radio or electronics shop for intercom cable. Be sure to check for the proper conductors.
In step four, you are ready to connect the master stations with the substations. Basement or attic space may be the best place to run the wires through to avoid wire clutters in your house. Be sure to make larger entry hole through the floor space for the master station because more cables will be running through it. For ease of identification label the cable for each substation location.
The next step is to connect the three wires at each substation to the terminals on its unit. Tighten the unit through a wall stud and smooth out the molding around the outer area of the wall.
Next, connect the power line to the master station. Make sure the home’s electrical system is disabled while you run the power line to avoid injuries. Some system are powered by transformer that accompanies your order. Keep the transformer close enough to a main entrance panel then connect it to the electrical system following the manufacturer’s guide.
In step seven, join the substations and power line wires to the master station following the markings on the terminal connections of the master station. Lift the station unto the wall and fasten it well to the wall studs. You can now return energy to the circuit. Again, always remember to disable the route while running your wiring to avoid electrical shock and other hazards.
In the final step, try the intercom to see if the system works. If all goes well, enjoy your new intercom system installed by you. If not, check for wiring or battery life for the substations that are powered by batteries and replace them. Things should be alright then.
You can now enjoy your intercom system as a security measure, to play music in the entire house, or just have fun with your family members calling each other within the compound.
