Circuit Types
The term circuits refers to an actual electrical interface, either initiating (detection) or NAC (signal). The term zone is a logical
concept for a fi re alarm protected area, and will consist of at least one circuit. Often the terms zone and circuit are used
interchangeably, but in this manual the term circuit is used.
