No problems with installation. Neat and tidy control unit with clear instruction leaflet. Four Opal external sensors also fitted. Equipment was replacement for Racal system which had been in use for 25 years, but which had suffered from failure of the I/R sensors with replacements no longer available. Identical wiring plan made task straightforward.
