What to do if you disconnect your home security system?

Contact the Alarm Company If you currently have a monitoring service, you want to make sure you contact them before you start disconnecting parts. Many monitoring services will automatically dispatch police if a wire is cut or power is lost to the service. If you don’t want the police showing up at your house, go ahead and make a quick phone call.

Why do I need to disconnect my phone line from my security system?

Additionally, if you have a cell backup unit installed, you no longer need a phone line connected to your system. You may want to disconnect it because you have discovered it is possible for someone to call your security system and hack into it, or if you have discontinued security monitoring.

What should I do if my home alarm keeps going off?

If the alarm keeps going off, it may be necessary to shut down the system until service can be arranged. If you have home alarm system monitoring, and/or use a home alarm company for service, call them before doing anything else. They know your system, and are in the best position to help you!

How do I disable my Home Security sirens?

The quickest way to disable the sirens is at the control panel. If the control panel is still active and has a “maintenance mode” setting, choose that. This lets the system know that you are working on it, not tampering with it.
