Alarm testing or account changes

Call (800) 564-8273 before testing alarms, changing the monitored device plan or providing sensitive account details. Coordinate test mode and restoration of normal monitoring.

Have this ready

  • Your order number, if the question concerns an order.
  • The exact panel or device model.
  • The device’s location name or label.
  • The full wording of any trouble message.
  • A description of what happened and what ordinary checks you have already tried.

A close-up photo can help explain an installation question. Keep alarm codes, passwords, private account records and payment details out of general messages or photographs.

If physical installation is not working out

Call Major to discuss the options. For Major monitoring customers, we can provide setup assistance by phone. We can also discuss help arranging a local subcontractor, or a return where the published return policy applies. Any on-site installation and its cost must be agreed separately; it is not included in the equipment price.

You may request a return of undamaged opened equipment within 60 days of the original shipping date, with no restocking fee. Customers pay ordinary return shipping and must obtain return authorization first. See the full policy for conditions and warranty procedures.

Written guidance and personalized support

All customers can use these free written guides. Major monitoring customers receive preprogramming, setup assistance and ongoing technical support, including help with additional equipment for an existing Major monitoring account. Equipment-only purchases do not include those personalized services.

Your next step

Written guides are available to everyone. Preprogramming, setup assistance and ongoing technical support are included with Major Home Security monitoring. Equipment-only purchases include free written guides, without personalized programming or technical support.
