What type of alarm system is self-contained and does not require off premises monitoring?

A local alarm system is designed to operate independently and is self-contained, meaning that it does not require external monitoring services or connection to a centralized monitoring station. This type of system typically has sensors, a control unit, and an alarm (such as a siren) all located on the premises. When triggered, the local alarm system emits a loud sound to alert individuals in the vicinity of a potential intrusion or emergency.

In contrast, the other types of systems involve some degree of external oversight or connectivity. For instance, a remote alarm system typically sends alerts to an outside monitoring center, requiring a connection beyond the premises. A central monitoring system refers to a setup where multiple alarms from different locations are monitored from a central facility. Lastly, a networked system often connects various devices across a broader network, which may include internet or cloud-based monitoring, thereby relying on external resources for its operation.

Thus, the local alarm system stands out for its self-sufficiency and independence from off-premises monitoring.
