The Honeywell Lyric alarm panel responds to RF jamming by alerting you with a warning and/or contacting the central monitoring station if it detects a signal jam for longer than 20 seconds.

What makes RF jammers so dangerous?

RF jammers are designed to block of the communications devices in a small radius, preventing your alarm system from contacting the central station. These devices can exploit gaping security holes that affect most of the cheaper alarm systems out there.


Although RF jammers are illegal in the United States, the online black market makes the devices accessible to criminals all over the world. Homeowners with larger houses are particularly at risk of being targeted by more sophisticated burglaries.

Fortunately, Honeywell equipment isn’t some ordinary consumer-grade junk that’s being handed out by most of the major security providers on the market. This is professional-grade stuff.

How does the Honeywell Lyric system stop jammers?

When a device frequency range (345MHz or 2.4ghz) has been transmitting for over 20 seconds, your Honeywell alarm panel displays an alert in the form of an exclamation point followed by number code that corresponds with the affected radio frequency.

There will also be some beeping noises that you can silence by pressing any button.

If you’ve enabled trouble reporting, your device will contact your Central Monitoring Station. Once the RF Jam condition is gone, you can clear the Trouble alert with a Disarm + Code entry.

The RJ Jam feature from factory comes activated with a RF Jam Log. To modify the Lyric controller RF Jam detection settings from the Lyric Controller’s home screen select Security > Tools > enter 4-digit installer code “default is 4112” > Program > System Type > Toggle RF Jam button to your liking.
