This allows much easier and safer installation of external accessories. There won‘t be needed to connect a power supply to external accessories that digital input could sense a change of a signal.<br /> <br /> <br /> Animated picture below shows a simple example of negative input usage scenario. There are many alarm buttons, sensors and other accessories that operate on this principle: one alarm button pin is connected to ground (it could be connected to any ground, not necessarily to FMB130 device ground), other pin – to negative input. When the button is pressed, ground is connected and negative input detects it.<br /> <br /> [[File:Negative_input_gif.gif|center|]]</div>
