One WiFi, 3 Sensor Tracks, 8 BPC2's, 30 ASC2's, 4 STM2's and 5 Boosters. This count includes 5 spares. In 4 years two ASC2's have failed and a third one works about half the time. No other type of LCS device has failed. The ASC2 failure mode has been failure to hold programming when turned off.
Regarding the large ASC2 count, in addition to the 45 turnouts there are a lot of uncouplers, action tracks and lights. The layout was built in 15 separate modules. A design decision was made that no LCS output wires would cross a module joint. Only power wires and PDI cables cross module joints. This means that an LCS component may not have all outputs used because a given module may not have enough of each type of device on it to require all the outputs of the LCS components mounted on that layout module. This design decision added about 15% to the LCS device count. Given that the layout was built in Miami, disassembled, shipped, reassembled and tested in my house this was the right decision.
