New construction vs. retrofitting intercom installation

The intercom system installation process will vary based on the type of building it’s installed in and the type of intercom being installed. New developments will plan for the intercom, while an existing building may have to adjust its infrastructure.

So, it’s vital for intercom installers to consider the unique factors that will impact the installation process.

Considerations for both types of intercom installation:

New construction	Retrofitting
Look for an intercom system early. There’s no easier time to install an intercom system than with new construction. So, choose an intercom system early in the design and planning phase. This way, architects can properly incorporate the system into the building plans — making the process easier and cheaper than a retrofit install.	Expect costs to be higher than a new construction installation. No matter the type of intercom system, a retrofit project will likely cost more than a new construction install. With that said, certain factors of the intercom can help lower the installation costs, such as being cloud-based and wireless.
Think about where to place the intercom. When planning your building’s layout, consider where to place the intercom and weigh the option of including more than one system. For example, a community with two vehicle entrances may want two gate intercoms installed. Conversely, an apartment building with a single primary entrance would only need one.	Evaluate your building’s existing intercom system. Buildings without an existing intercom need the proper wiring to support the system. Even wireless options will require some wired connections for power and internet. As for buildings with an intercom already, replacing it isn’t as simple as many might think since most systems have different wiring and installation requirements.
Determine how the intercom will be used. This consideration is especially important for new developments because they don’t have any residents yet. For instance, if your intercom is installed at a vehicle gate, users will be sitting. So, the system must be installed at the right height. Otherwise, it may be difficult to reach, creating issues for people accessing the property. Moreover, the intercom will likely need a pedestal if a nearby wall is unavailable.	Wireless vs. hardwired intercom system. A wireless intercom requires minimal wiring, so it reduces the difficulty and the cost of installation. Rather than needing hardware installed in every unit, wireless intercoms use mobile phones as substations. Conversely, wired intercom systems require extensive wiring to individual unit substations throughout the property. So, for a simpler solution with lower costs, consider installing a wireless intercom.
