Frequently Asked Questions

Most trouble beeps can be silenced by pressing the # key or the "Silence" button on your keypad. The trouble condition will still display until resolved. If the beeping continues, call our service line and a technician can walk you through the issue or schedule a service visit.

An amber light typically indicates a trouble condition — this could mean a low battery, a communication issue, or a sensor fault. It does not necessarily mean your system is unprotected. Call our support line and we can help diagnose the issue remotely.

After a smoke detector activation, the system may need to be manually reset. Try entering your master code followed by the "Off" key. If the trouble persists, the detector may need to be cleaned or replaced. Contact us for assistance.

Yes. Call our monitoring office at (636) 255-0250 before you leave and we can update your contact list for the duration of your trip. We'll restore the original list when you return.

Before testing, call our monitoring office at (636) 255-0250 to put your system on test mode. This prevents a false dispatch. Once on test, activate the sensors you'd like to verify. Call us again when you're done so we can take the system off test.

This can happen if the alarm signal didn't reach our station — possible causes include a phone line issue, internet outage, or a communication module fault. Contact us immediately so we can check your signal path and resolve the issue.

Yes. All alarm systems we install include a backup battery that provides power during an outage (typically 4–24 hours depending on the system). Your system will continue to function and communicate with our monitoring station.

Absolutely. We can install additional contact sensors on cabinets, safes, or specific doors and configure custom notifications that alert you by email or text when that sensor is triggered.

This usually means a zone is faulted — a door or window may be open. Check that all entry points are closed and try again. If you still can't arm, call our support line and we'll walk you through it.

The A24 Interactive app is available on the Apple App Store and Google Play Store. Search for "A24 Interactive" or "Alarm.com" (depending on your system). Contact us if you need help with setup or login credentials.

Always call 911 first in a life-threatening emergency. Our monitoring station will also dispatch authorities when your alarm is triggered, but direct 911 calls receive the fastest response. After you're safe, contact us for follow-up service.

A continuous tone from a DVR usually indicates a hard drive failure or overheating issue. Power down the unit and call our service department. Do not attempt to open or repair the DVR yourself.
