  3. Ease of Use: Modern intercom systems are designed with user-friendliness in mind, making them easier to use for both occupants and visitors. This can help avoid confusion and ensure that the system is used effectively.
  4. Scalability: Newer intercom systems are more easily scalable, allowing you to expand or modify the system as needed. This is particularly useful for growing properties or those that undergo frequent changes in occupancy.
  5. Compatibility with Modern Technology: Upgrading to a new intercom system ensures compatibility with modern technology and devices, such as smartphones and tablets. This can provide additional convenience and functionality for users.
  6. Reduced Maintenance and Repair Costs: Older intercom systems like Nutone may require frequent repairs and maintenance, which can be costly and time-consuming. Replacing the system with a modern alternative can reduce these costs and ensure more reliable operation.
  7. Enhanced Aesthetics: Modern intercom systems often have sleek designs that can improve the appearance of your property. This can contribute to a more professional and appealing environment for occupants and visitors.
  8. Energy Efficiency: Newer intercom systems may consume less power than their outdated counterparts, leading to lower energy bills and a reduced environmental impact.
  9. Increased Property Value: Upgrading your intercom system can be an investment in your property, as it may increase the overall value and desirability of the building to potential buyers or renters.
  10. Future-Proofing: Replacing an outdated intercom system with a modern one ensures that your property remains up-to-date with the latest technology and industry standards. This can help prevent obsolescence and maintain the relevance of your communication infrastructure.

Assessing the Current System

First, it is important to determine the type of system that is currently in place. Older intercom systems may be analog, while newer systems are likely to be digital. Analog systems can be easily replaced with a digital system, which offers more features and functionality.

The first step in replacing an intercom system is to assess the current system and identify its limitations. This includes identifying any issues with the wiring or hardware, as well as any features that are missing or outdated. If the entry panel has a brand name and model – search for its characteristics. Once this has been determined, the building owner or property manager can begin researching new intercom systems that meet their needs.

When choosing a new intercom system, it is important to consider the size and layout of the building, as well as the number of units or offices that need to be connected. Additionally, the system should be compatible with the building’s existing wiring, and it should be easy for both occupants and visitors to use. Keep in mind that BAS-IP building intercom system works over the existing local IP network.

It is also important to consider the features of the new system, such as video communication, door release, and integration with other security systems. These features can enhance security and convenience for tenants, and they may be especially useful in high-traffic areas such as apartment buildings or office spaces.

Installation and Testing

Once a new system has been chosen, the next step is to install the new hardware and wiring. This may involve running new wiring throughout the building, as well as installing new call panels and receivers. Depending on the size and complexity of the system, this may require the assistance of a professional installer.

After the new system has been installed, it is important to test it thoroughly to ensure that it is working properly. This includes testing the call panels, receivers, and any other features that have been installed. It may also be necessary to provide training to occupants and visitors to ensure that they know how to use the new system.

Exploring Newer Options

In addition to traditional intercom systems, there are also newer options that can be used to replace an outdated system. For example, some buildings are now using smartphone apps to facilitate communication between occupants and visitors. These apps can be downloaded onto smartphones or tablets and allow tenants to receive calls from the building’s entry panel directly on their device. This can be a convenient and cost-effective option for smaller buildings or those with a limited number of units.

Another option for replacing an intercom system is to use a cloud-based system. These systems allow occupants to communicate with each other and with visitors via the internet, eliminating the need for physical hardware or wiring. Cloud-based systems can be especially useful for larger buildings or those with a complex layout, as they can be easily scaled up or down as needed.


In conclusion, replacing an intercom system may seem like a daunting task, but it can be a relatively straightforward process with the right planning and preparation. By assessing the current system, choosing a new system that meets the building’s needs, and installing and testing the new hardware and wiring, building owners and property managers can ensure that their occupants have access to a modern and efficient communication system. Additionally, with newer options such as smartphone apps and cloud-based systems, there are now more choices than ever when it comes to replacing an outdated intercom system.


Q: How much does it cost to replace an intercom system?

The cost of replacing an intercom system depends on various factors, such as the type of system being installed, the size and layout of the building, and the features included. Generally, the costs can range from a few hundred to several thousand dollars. It is important to research different options and get quotes from multiple vendors to determine the best fit for your budget and requirements.

Q: Can I install a new intercom system myself?

While it is possible for some individuals with technical expertise to install a new intercom system, it is usually recommended to hire a professional installer, especially for larger or more complex systems. Professional installers have the necessary tools, knowledge, and experience to ensure a seamless and efficient installation.

Q: How do I choose the right intercom system for my building?

When choosing an intercom system, consider factors such as the size and layout of the building, the number of units or offices, compatibility with existing wiring, ease of use, and any additional features you may need. It is also helpful to read reviews and consult with professionals to ensure you are making an informed decision.
