In a local alarm system, what does the term "local" refer to?

In the context of a local alarm system, the term "local" specifically refers to a system that activates a siren or alarm sound at the location of the system but does not have the capability to send notifications to authorities, such as the police or fire department. This means that while the alarm will alert individuals in the vicinity—potentially scaring off an intruder or signaling a fire—it does not automatically notify external agencies to respond.

The primary function of a local alarm system is to provide immediate auditory alerts within its location, serving as a deterrent or a warning for those nearby. This characteristic distinguishes it from other alarm systems that might have more advanced communication abilities to alert law enforcement or monitoring services.
