Five ways to manage your system at home and on the go

With Xfinity Home, you can access your system from anywhere, on any device. Use any of the methods on this page to arm/disarm your system, monitor system status, review the latest activity and view live video.

1. Xfinity Home app

Download the Xfi nity Home app to access your system on your mobile device and customize rules.

  • The app will ask for permission to add the Xfi nity Home SMS and Professional Monitoring Station phone numbers as contacts to your device. This allows your device to quickly identify text messages from Xfi nity Home if your security alarm goes off or there is an important message. Tap OK.
  • Once the app is installed, sign in using your Xfi nity username and password and set up Touch ID, Fingerprint ID, or Face ID, if applicable.

2. Xfinity X1

  • Manage your system settings
  • Personalize Keypad Codes for family, friends and anyone who needs access to your home
  • View the weather
  • Send an emergency alarm

IMPORTANT: Do not unplug or move your Touchscreen Controller from its install location. Doing so may interrupt Professional Monitoring connectivity and service.

5. Wireless Keypad

Your system may include a wireless keypad. This device can live anywhere in your home and allows you to arm/disarm your system.

Arm and disarm your system

Your system responds differently depending on which arm setting you choose. Learn the meaning of the three arm settings and when to use each one:

Here is how your system responds to each arm setting:

Important arm/disarm informationThe Professional Monitoring Station is immediately notified of any sensor trip. Entry/Exit delay refers to the time allowed to disarm the system before the alarm is processed by the Professional Monitoring Station for the possible dispatch of authorities. Entry delays occur when a door is opened while the system is armed and Exit delays occur immediately after arming the system. Entry/Exit delay is configurable by a technician.

In Night mode, motion sensors are not activated by default, but your technician can reconfigure these settings at installation upon request.

How your alarm works

In the event that your alarm is triggered, this is the chain of events you can expect.

Important Keypad Codes and Passcodes

These are the codes you and your family need to know in order to control your security system. Go to page 15 of this guide to write in codes for future reference.

Master Keypad Code

Your Xfinity Home system can have only one Master Keypad Code; this code allows users to:

  • Arm and disarm the system.
  • Cancel an alarm from the Touchscreen Controller, Subscriber Portal and any device with the Xfinity Home app.
  • Add, change and delete Secondary Keypad Codes.
  • View and change all Touchscreen Controller settings.

Secondary Keypad Codes

You can add Secondary Keypad Codes for family members or friends who only need limited access to your system. Secondary Keypad Codes cannot be used to add, change or delete other codes.

Central Station Passcode

This security feature allows you to identify yourself or someone you trust to the Professional Monitoring Station in the event of an alarm. In addition to your Keypad Codes, you must choose your verbal password during your initial system setup, but you can easily change it whenever you’d like.

Quick Tip: If you are in a duress state during a triggered alarm situation and provide the wrong Central Station Passcode to the Professional Monitoring Station, they will notify the authorities.

Make sure your emergency contacts know your Keypad Codes and Central Station Passcode to ensure they can respond to any triggered alarm.

Updating your emergency contacts

Your Emergency Verification Contacts will be called if the alarm is triggered. Your Emergency Dispatch Contacts will be notified when an emergency has been verified and authorities are on their way. It is critical to keep both updated. It’s easy to set up or change your emergency contacts:

  1. Log in on the Xfinity Home mobile app.
  2. Under Settings, click Security and scroll to Emergency Dispatch Setup or Emergency Verification Setup.
  3. Click Add Contact.
  4. Enter the contact information and press Save.

Make sure your emergency contacts know your Keypad Codes and Central Station Passcode so they can respond to any triggered alarm.

Quick Tip: Be sure to add the Professional Monitoring Station phone number – 844-382-9363 – to your contacts to recognize our call in case of emergency.

Customize your system by setting rules

Rules are personalized commands designed to control your home’s devices. You can create rules based on your lifestyle for simpler, more efficient home management. Create a rule:

  1. To get started, log in to the Xfinity Home mobile app.
  2. From the toolbar, select Automation.
  3. Select Create a Rule.
  4. Follow the on-screen prompts to create your customized rules.

Rule examples:

  • Scenario 1: Want to know when the kids made it home after school? Add a rule to receive a text when the front door opens in the afternoon.
  • Scenario 2: Add a rule to receive a text message about your system status.
  • Scenario 3: Add a rule for the front-door camera to take a video when the door is opened after midnight.

How to prevent false alarms

False alarms can pull first responders away from real emergencies, and sometimes result in fines from local authorities.

  1. Assess the activity in your homeIf you expect activity inside your home, set your system to Stay to deactivate your motion sensors. If you are away, set your system to Away and be sure to keep your motion sensors away from large fans, heaters, curtains and plants.
  2. Download the Xfinity Home appYou can use the app when you’re away from home to quickly verify an alarm, and if needed, cancel an emergency dispatch.
  3. Know how to cancel an alarmIf an alarm is unintentionally tripped, you can cancel the alarm by disarming the system with the Xfinity Home app, the Touchscreen Controller or the Wireless Keypad. If the Professional Monitoring Station calls, you can also cancel using your Central Station Passcode.
  4. Keep emergency contacts updated and informedIn the event of an alarm, if your primary contact does not answer, we will try to reach your emergency verification contacts. Contacts must know the Central Station Passcode to cancel the alarm.
  5. Monitor and change sensor batteries                                                                                  The Touchscreen Controller will alert you when sensor batteries are low. Visit to learn how to replace a low battery.
  6. Test your system                                                                                                             Testing your alarm every month ensures that your system is working properly and is ready to respond to any issues. Use the alarm-test mode when testing the system or changing batteries in your devices to avoid setting off a false alarm.
