These instructions apply if the enhanced alarm out annunciation feature in the Doors software has configured these
outputs for door held open annunciation. The DHO alarm feature is not available in 16-bit Doors software applications.
If you are not using the DHO feature, skip to the General-Purpose Outputs sections on page 8.
