Abstract:

A system and method for false alarm prevention in unstable locations is presented. In one embodiment, the method comprises activating an asset sensor and a reference sensor, detecting motion in the asset sensor, determining if the reference sensor detects motion, and preventing transmission of an alarm if the reference sensor detects the motion. In another embodiment, the method comprises activating an asset sensor and a reference sensor, detecting motion in the asset sensor and transmitting acceleration data in accordance with the detected motion, sensing local acceleration data from the reference sensor, and signaling an alarm if a difference between the transmitted acceleration data and the local acceleration data is greater than a predetermined threshold. The reference sensor can be mounted in a control panel, and the asset and reference sensors can be enrolled in the control panel.
