Abstract
Continuous status monitoring of a plurality of switches and smart sensors associated with the switches, wherein each sensor is connected to a separate single point in a single wire bus is a affected by a smart sensor multiplex arrangement employing an automatic wake-up circuit. The automatic wake-up circuit allows activation of any switch of a group of high priority switches to automatically take a microcontroller out of a wait mode and causes it to go into a POWER-ON mode. In the POWER-ON mode, power routes all circuits in the entire system and then a polling of all the switches and sensor modules is performed.
