1. A method comprising:
- determining, at a controller of a device of a premises management system, the device having a head unit and a backplate, at least a partial removal of the head unit from the backplate based on a position of a removal switch that detects connectivity between the head unit and the backplate;
when the controller determines that the position of the removal switch is in an open position, continuously determining, at the controller, an orientation of the head unit based on an output signal from an accelerometer coupled to the head unit;
determining, at the controller, whether the orientation of the head unit is within a predetermined range of orientations; and
outputting, at the controller, a tampering signal based on the open position of the backplate removal switch, the determined orientation of the head unit, and when the determined orientation is outside of the predetermine range of orientations.

Abstract
Systems and methods are provided for determining, at a controller of a device of a premises management system having a head unit and a backplate, at least a partial removal of the head unit from the backplate based on a position of a removal switch that detects connectivity between the head unit and the backplate. When the controller determines that the position of the removal switch is in an open position, an orientation of the head unit may be continuously determined based on an output signal from an accelerometer coupled to the head unit. A tampering signal is output based on the open position of the backplate removal switch and the determined orientation of the head unit.

11. A device for a premises management system comprising:
-
a head unit coupled to a backplate; a removal switch to detect connectivity between the head unit and the backplate; an accelerometer to determine an orientation of the head unit; and a controller to determine at least a partial removal of the head unit from the backplate based on a position of the removal switch, and when the controller determines that the position of the removal switch is in an open position, the controller continuously determines an orientation of the head unit based on an output signal from an accelerometer and determines whether the orientation of the head unit is within a predetermined range of orientations, and the controller outputs a tampering signal based on the open position of the backplate removal switch, the determined orientation of the head unit, and when the determined orientation is outside of the predetermine range of orientations. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
