All this to re-engineer a 40 year old system is ridiculous. I know it is possible, an old Westinghouse hand could do it. But you are messing with group operation, maybe fire recall, if it has that. Call electrodyne or a similar company that has engineers and insurance. The Hotel really needs to upgrade to a whole new system. An Overlay will address the problem but it really isn't the best way. Doing this as a Technician should not be an option.
I agree, they need to mod. Although I hate overlays, an MCE would cut out the dispatcher and control fire service and all the code requirments of today.
I have an old 1968 REL job that had an MCE overlay installed in 1995. I'm starting to have issues with the MCE, it's almost 20years old. Who relies on a 20 year old car to get to work, much less a 46 year old elevator to keep guests happy?
