Overview

The PROSIXPIR is a wireless motion sensor that detects movement inside your home or business. If the battery becomes low, your alarm system will display a low battery alert. Replacing the battery is quick and can usually be done without a technician.


Before You Begin

Before replacing the battery, please call us at (718) 360-9191 so we can place your alarm system in Test Mode. This will help prevent unnecessary alarm signals from being sent while the battery is being replaced.
