False alarms can take first responders away from real emergencies, cost you money in fines from local authorities and create a public nuisance. Keep these tips handy to prevent false alarms with your XFINITY Home system.

  1. Know your system.
    • Read the user manual to get comfortable with how your system works. Make sure everyone with a key to your home knows how to use the system properly. If you need another user manual, you can download it at XFINITY Home User Manuals.
  2. Keep your contact information current.
    • Provide at least two Call to Verify and two Call to Notify numbers that will be contacted in case of an alarm. You can set up text alerts as well.
    • It's important to save the monitoring station's phone number (1-800-633-2677) to each of the phone numbers that are listed on your account to help you identify and answer any monitoring station calls.
  3. Know your Central Station Passcode.
    • In the event of an alarm, expect a call from the Central Monitoring Station. Provide your passcode so they know it's a false alarm. Make sure everyone in your family knows your passcode.
  4. Keep areas around motion detectors clear.
    • Keep fans, heaters, plants, curtains, seasonal decorations, etc., away from motion detectors.
  5. Notify us if something changes.
    • Contact us if you remodel or think your system is not functioning properly. And tell us when you receive your permit number (where required).
