In what year were sprinkler and fire alarm systems required to be monitored by a central alarm company?
Which code NFPA or IFC?
I would say it depends on the ahj, when they started requiring it.
I have a 1988 Uniform Fire Code, that says monitor or local alarm, for fire sprinkler systems.
Why the question???
In what occupancy types? Not all sprinklers or fire alarms are required to be monitored by central alarm companies.
