Fire Alarm/Elevator Phone Lines

[Douglas Stewart]

Does anyone have an experience with these types of phone lines? My understanding is that there must be two POTS lines for the fire alarm and one for each elevator. The building I'm working for is paying almost $1000/month for four of these lines. Is this normal? Does anyone have any resources where I can read about the requirements for these lines? Are these lines typically serviced by the major telecoms like ATT or are there other service providers where we could potentially save money here?
