Abstract:
1. A device with single main control unit (MCU) based motion detection, local alarm and supervisory arrangement for alarm system controlled by an alarm control panel (ACP), comprising: a sensor component monitoring environment of said alarm system to generate a reference information, wherein said sensor component comprises an energy sensor adapted for defining a detecting area and detecting energy directed within said detecting area to produce inputted energy signals; an output component communicatively connected with said ACP which is adapted to generate warning messages; a power supply component providing power for said device wherein further comprises an auxiliary (AUX) power supply provided by said ACP and a backup power supply providing power for said device when said ACP is not available; and a microcontroller communicatively connected with said sensor component for receiving said reference information therefrom and drive said output component according to said reference information, wherein said microcontroller monitors said ACP and enables said backup power supply when said ACP is not available, wherein said inputted energy signals from said energy sensor is processed by said microcontroller which comprises a means for converting said inputted energy signals into data samples, wherein a plurality of data samples are constructed to form a predetermined number of constructed sample window of constructed samples in time, wherein a control range is determined for each of said constructed sample windows, and thus by comparing said relationship between said successive constructed sample windows, said microcontroller is capable of determining whether there is an need to send alarm signals to said ACP.
