When a SENSING-SAF-START® is installed on any equipment and there is an electrical power interruption to the equipment, the SENSING-SAF-START® will open the circuit so when the power source is restored, the SENSING-SAF-START® will prevent the equipment from restarting. The SENSING-SAF-START® will not reset until the equipment switch has been turned "off". There is a sensing circuit within the new SENSING-SAF-START® that sends a signal up to the equipment switch to see if it is in the "on" position. If the switch is still "on", the SENSING-SAF-START® sounds a warning buzz when the reset button is depressed, and it will not close the circuit until the equipment switch is turned "off". Then, and only then, the SENSING-SAF-START® will close the circuit, so the equipment will operate again.
