The days of key system installers having job protection are nearly over. Face it, they are easy to install and some now have GUI interfaces. I am quite certain we will be leaving the key system market again as we have found that it's basically not worth it anymore. 90% of the crap (maint) service calls are made from 10% of the ports we service ie. the key systems. They complain the most and pay the least. I don't know how anyone makes money in these size ranges IMHO. We have been playing with the small systems for a couple years now and IMHO the next board meeting I am voting to nuke them and go back to the larger systems as that is our bread and butter.
