13. The apparatus according to claim 5 wherein the input information collected by the at least one sensor is processed using a Silicon Controlled Rectifier (SCR) or transistor to convert an incoming voltage spike to an output pulse of between 0 and 5 volts, to create a compatible pulse output to trigger an electronic/digital timer.

14. The apparatus according to claim 13 wherein the minimum sample time for the incoming pulse is greater than 125 uS to allow the processor to identify the input.

15. The apparatus according to claim 13 further including diagnostic features to help diagnose faults and ease installation.

16.
