It sounds to me as though you already have the answer for the phone, so why ask? But keep in mind, anything that happens to anyone in that elevator is your responsibility once you change it. Lawyers are relentless and will dig up every piece of paper available on the unit....they will get everything from the manufacturer first.
As far as the ups in the event of a power failure, There is more to than simply buying one and setting in the room. None of them will come with instruction that pertain to implementing the unit into the system. I suggest you contact a company that has trained, certified field technicians. Superintendents and sales people will not have the knowledge of what is needed to safely do the task to which you are inquiring.
Are you talking about first hand experience with the lawsuits?
Are you saying they will charge you with kidnapping if the elevator gets stuck? I did not know this was an industry of lawyers for elevator problems.
Just trying to keep up with technology.
Thanks.
