Hi all Of of my partners is willing to sell an EDA able to provide the "dead man fall" functionnality. to a company in charge of security.  The job of the employees of that company is to check out of normal Business hours (the night) that isolated plants have not been robbed. I know that the accelerometer is a prerequisite  so this could work with the MC75A MC9500 MC3100?? ES400? Has someone any feedbacks? Has anybody already developped such an application? Thank you for your help Philippe
