As men-tioned, the user will receive all software features except for theoptional closed transition.The "P" and "S" (programmable, stan-dard) included in all ATC-900's.The difference is that the "P"refers to the I/O programming. If the switch requires more I/Othan 4 in or 4 out, an I/O Module will be required. The right col-umn shows the I/O required for that particular option.The fixed I/O is required when a switch on the door may be usedto enable an option.
