Wireless motion sensor triggers AAA Home Monitoring System alarm. Expand your AAA Home Smart Center home security system by installing motion detectors in additional locations in and around your home. The Motion Sensor for AAA is a wireless motion detector designed to monitor indoor and outdoor areas of your home, sending a wireless alert to your home security system upon a breach. The AAA Home Smart Center home security system (AM-100) is sold separately. Each zone in the AAA Home Smart Center home security system can support two sensors, so you can install a motion detector in numerous locations, such as your entryway, overlooking your back yard, or in various rooms. If the Motion Sensor for AAA detects movement in its 40-foot range, it immediately sends an alert signal to the AAA Home Smart Center, which can sound an alarm, call out to up to five phone numbers, or trigger another event, depending on how you have set up your security system. The Motion Sensor for AAA stands on the included mount, attaching to a wall or ceiling with the included mounting hardware. You can adjust the sensitivity of the detector, if desired. The AAA Home Smart Center supervises the sensor and its battery condition automatically, alerting you immediately if something is wrong. This sensor can also trigger the Audio Alarm for AAA (AA-433) (sold separately).
