They'll determine if it's a fixable issue or if you need a replacement. This process isn't covered in monthly fees. You'll often need to pay for shipping, and it can take weeks.

Monitored Systems

You'll still need to pay $150 or more for in home repairs for monitored systems. That's in addition to your $300 average monitoring service fee. If you still have a warranty on your parts and labor, you won't have to pay anything. However, you'll likely have a dedicated service department with your monitoring service to do the work. Contact your monitoring service first. You'll also find technical support for free from your service.

  • False alarms: Essentially, the alarm goes off without any apparent reason, which in some areas can result in fines from local law enforcement.

  • Faulty window or door alarm contacts: The circuit breakers for one or more windows no longer functions properly.

  • Alarm battery replacement: Wireless systems use batteries that need occasional replacement

  • Bad power supplies: Usually a faulty main power supply or wiring connections

  • Annoying alarm beeps: Constant beeps for no discernible reason. Sometimes, it's as simple as the battery.
