A smaller shared entrance has different requirements from a large apartment block or commercial development. That's why Commtel offers systems such as the JUNIOR, MILLENNIUM and SENIOR, giving installers the flexibility to specify the right intercom for the way the site will be used.

Not sure which system is the right fit? Our team is here to help. Give our Sales team a call on 01306 710 120 (option 2), or find out more in our 4G Intercom Buying Guide: https://www.commtel.io/blog/choosing-a-4g-intercom/

When a system behaves inconsistently, the cause isn’t always obvious at first glance.

Programming, relays and connectivity are all natural places to start. But on larger installations, longer cable runs or systems with multiple connected devices, the amount of power reaching the equipment can also affect how reliably it behaves.

Keeping power in the fault-finding process can help narrow down the cause sooner, particularly when symptoms are intermittent or only appear once the full installation is operating.

Swipe through for a few signs that power may be worth checking alongside configuration, relays and connectivity.

When a live site doesn't behave as expected, the activity log can tell you what happened.

The latest NX update adds optional event recordings, giving additional context when reviewing activity.

Whether you're checking how access was granted or investigating an unexpected relay trigger, recordings can now be linked directly to activity log entries.

More context when reviewing activity. Less time working out what happened.

People change. Site requirements change. The system needs to change with them.

Whether it's adding a PIN for a new member of staff, updating a callpoint when a resident moves out, or changing where calls are received, Commtel systems are designed so those routine changes can be managed remotely through the CONFIG app.

That gives you a straightforward way to support your customers as their requirements evolve, without routine programming becoming another job on site.

Every site has different requirements. Choosing the right intercom starts with understanding how the entrance will be used.

A converted property, shared office or multi-occupancy building may only have one entrance, but that doesn't mean one call button is enough. Thinking about how the site will operate from the outset makes it easier to specify a system that supports today's requirements and tomorrow's.

Programming authorised users isn't always necessary.

For sites where anyone can operate the entrance by calling the Command Unit, the latest firmware introduces a simpler way to trigger the relay.

If no authorised numbers have been added, the Command Unit rejects the incoming call and activates the relay automatically. They simply call the number to operate the entrance.

Find out more about the latest firmware updates and how the Command Unit works in our latest blog: https://www.commtel.io/blog/what-is-a-4g-command-unit/

4G performance starts long before the intercom is powered up.

Choosing the right SIM supports connectivity, remote programming and ongoing management throughout the life of the installation.

Some sites don't need a complex specification.

One entrance. One property. One point of contact.

The challenge isn't finding the intercom with the longest feature list. It's choosing one that's right for the application.

The SOLO+ provides the functionality needed for single-entrance sites without specifying a larger multi-user system or adding unnecessary complexity.

Because the right specification starts with the site, not the product.

The installation might be finished, but requests for changes rarely stop there.

Whether access needs updating, permissions need changing, or activity needs reviewing, routine administration can often be handled through the Commtel CONFIG app.

No searching for programming cables. No standing in front of a panel to make a small change. Just straightforward management when the site's requirements evolve.
