are there two risers? was it two groups before? if you have two risers you can easily switch it to SRO (separate riser operation). that way you won't have to mess with fire service. if they are spending money they should add hall call card readers to prevent the double calls and use EHS (emerg. hospital service) to the big car for patient transport. the good thing about otis equip is everything is in the existing software you just need to know how to turn it on. find out the exact intent of the change and i can make a few suggestions that you should bring up to the local office.
