(1) An Optional Second Sensor can be connected to the Control Board at J3 or OPT2 (See page 12 for connection information). The Optional
Second Sensor negates the actions caused by the Door Sensor when the Door is Open. The Outside Red Light, Interlocks and Outlets are
turned off.
(2) At the core of the Smart Chock Control Board is an embedded microcontroller. Under preprogrammed control, the Smart Chock Time
delays, Light Outputs and Relay Outputs can be modified to suit any Customers individual needs. For example, the Time Delays could be
preprogrammed anywhere from 3 to 15 seconds.
