Alarm.com Dual-Path Communication Failure - Cellular: What It Means and Who to Call

Your Alarm.com app or website shows a message that reads Dual-Path Communication Failure - Cellular. Nobody has called you about it. Is the alarm still working? Who do you call?

PAX Security7 min readNovember 9, 2026
Quick Answer

Alarm.com says this message means your panel is currently unable to communicate through the cellular network and is only communicating through the broadband network or Wi-Fi. It adds that until it is resolved, your panel is without back-up communication and will stop working if you lose power or you experience a broadband or Wi-Fi outage.

In plain terms: your alarm has lost its second way to reach the outside world. It is relying on the building's internet alone. If that internet goes down, there is nothing behind it.

Call the company that monitors your alarm and your alarm company. Alarm.com calls the alarm company your service provider. They may be the same company or two different ones. This is not something to fix yourself.

If there is smoke, fire, water, a break-in or anyone in danger, call 911 first. A trouble message never changes that. Until this is fixed, if something happens and the building's internet is down, call 911 yourself. Do not wait for the alarm to report it.

Key Takeaways

  • 1What it is: a trouble condition, not an alarm. Alarm.com says the panel cannot use the cellular path.
  • 2Why it matters: with no cellular back-up, an internet outage or power loss can leave the panel unable to communicate.
  • 3Who to call: your monitoring company and your alarm company (Alarm.com's "service provider").
  • 4What not to do: open the panel, pull its battery, unplug it or reset it.

This guide explains what Alarm.com says the message means, what you can safely look at, and who to call. It does not ask you to touch the alarm panel.

If you are not sure which company runs your Alarm.com account, read why your Alarm.com account runs through your alarm company first. For what an internet or power loss does to a security system, see what happens when the power or internet goes out.

What "dual-path" means

Alarm.com's page describes a panel that can communicate in two ways: over the cellular network, and over the building's broadband network or Wi-Fi. That is the "dual" in the name. The message you are seeing says the cellular path is down and only the broadband or Wi-Fi path is working.

Nothing on the customer page says why the cellular path failed, and we cannot tell that from the message either. It could be a signal problem at the panel, or something else. That is a question for the company that installed or services your system.

What you can safely do

All of this is look-only, from your phone or computer:

  1. Tap the trouble message. Alarm.com says that tapping a trouble condition wherever it appears gives you more information, which may include basic troubleshooting steps and your service provider's info.
  2. Write down the exact wording on the screen, the date and the time you saw it. Take a screenshot.
  3. Check whether the building's internet is working. Connect a phone to the building's network and open a web page. The panel is relying on the broadband or Wi-Fi path right now, so a lost internet connection matters. If the building has no internet, tell your internet provider or building engineer, and tell your alarm company that both problems are happening at once.
  4. Look at the panel from where you stand, without touching it. Note whether it is showing a message, a light or a beep that you can describe. Light and message patterns differ by panel, so describe what you see and do not guess what it means.
  5. Alarm.com's one customer step: if possible, move metal or electrical objects away from the panel to improve cellular network signaling. One limit from us: move only loose items that are plainly yours to move, such as a small box or a cart left against the wall near the panel. Leave shelves and anything heavy or fixed where it is. Do not unplug anything, do not move wiring, and do not touch the panel itself. If an electrical item is involved, leave it and tell your alarm company.

Do not open the panel, pull its battery, unplug its power or try to reset it. Do not follow installer instructions you find online. Alarm.com publishes separate installer-facing pages that are not meant for customers.

Who to call

Start with the company that monitors your alarm. They are the ones who need to know the panel may not be able to report.

Then contact your alarm company, which Alarm.com calls your service provider. Alarm.com's Contact your service provider page says you can find their contact information in the Alarm.com app and on the customer website, and that it can often also be found on yard signs, window stickers or a billing statement. In the app, Alarm.com says to log in, tap the menu icon, tap Support, and then choose Phone Number, Email, Support Website or Support Ticket. On the customer website, log in and click Support. Alarm.com notes that depending on your service provider, not all four options may be available.

If you are not sure which company monitors your system, check your monitoring contract or a billing statement. Our guide on how your Alarm.com account runs through your alarm company explains why the company on your bill matters.

When to call us

Call PAX if:

  • You cannot find who monitors your alarm or who your service provider is.
  • You have called your alarm company and nobody has answered.
  • The message stays on your screen after your alarm company says it is handled.
  • You manage several buildings and are not sure which ones have the message.

If you see smoke, smell burning or find water near the panel, keep away from it, leave, and call 911 first.

Frequently Asked Questions

Does this message mean my alarm is not working?

Alarm.com does not say that. It says the panel cannot communicate over cellular and is only communicating over broadband or Wi-Fi, and that it will stop working if you lose power or have a broadband or Wi-Fi outage while this is unresolved. Treat it as a message that needs a call, not one to ignore.

Is this the same as an alarm going off?

No. Alarm.com lists it as a trouble condition. If you think there is an emergency, call 911.

Can I fix it from the app?

Alarm.com's customer page gives one step, which is to move metal or electrical objects away from the panel if possible, and otherwise to contact your service provider. It does not give an app-based fix.

Do I need to restart my internet to clear it?

Alarm.com's page does not say to. Do not restart anything on your own. If the building's internet is down, report that to your internet provider and your alarm company.

Why does Alarm.com send me to my alarm company and not to Alarm.com?

Alarm.com's customer page says to contact your service provider if you need more support. Our guide on why your Alarm.com account runs through your alarm company explains how that works.
