Intercom System Basic
Components of a Basic Intercom System
Primarily, there are two main parts of an intercom system, which include the master station and substation. In the part of the building or home where communication is needed to be received, a master station is installed. On the other hand, the area where communication originates has a substation.
this is the purpose of the intercom system, then it is necessary to have the substation installed outside
the door (commonly positioned on the wall) while the master station remains at the lobby desk.
Functions of the Master Station and Substation
The intercom system's main control area is found on the master station. There are essential parts in the master station such as the talk button, volume control, amplifier and station selector switch. Unlike the master station, the substation comes with only two components, which are the call button and speaker.
So, it only requires a single press on the substation's call button once a person needs to talk to the receptionist inside the office.
After pressing the button, any sounds originating from the substation is heard by the receptionist. Then,
the talk button on the master station is pressed by the receptionist, so he or she could talk to the visitor. The idea is each time a button is pressed (whether it is the call or talk button), communication is made possible. Then, releasing the button allows the person to listen to any replies made by the one he or she
is talking to on the other side of the room. Once the conversation is over, the station selector switch is pressed the second time as this causes the connection to be terminated.
Additional Facts about the Intercom System
There are instances when having multiple substations is necessary since this allows for communication
to be made with several locations. In this case, a master station that functions with a number of
substations comes with a station selector switch that is compatible for each of the station. There is also
an indicator light and label found in each switch, so this helps people understand the substation that corresponds to these.
It is also worth noting that intercom calls may be needed to be received at various locations in the
building. Hence, multiple master stations are required, and these an communicate with various
substations. Basically, one master station answers and handles the call while the rest of the master stations only ignore it. It is also not possible to use other master stations when one is currently in use.
With this basic information about intercom system, you should be able to determine which one works
for your needs before having it installed in your home or office building.
