Which type of alarm system connects directly to a monitoring site owned by the building's owner?

Proprietary systems are designed to connect directly to a monitoring site owned by the building's owner, allowing them to have complete control and oversight of the alarm system. These systems are often utilized in settings such as large commercial buildings or facilities where the owner wants a dedicated response to alarms without relying on third-party service providers. By being directly connected to a proprietary monitoring site, the owner can manage the system's operations, ensure timely notifications of alarms, and respond promptly before a potential incident escalates. This is particularly advantageous in terms of emergency response times, as the owner can act immediately based on the nature of the alarm.

The other options represent different types of alarm monitoring arrangements. For instance, remote station systems typically send signals to an off-site location but are not directly managed by the building owner. Central stations usually refer to third-party monitoring services that receive signals from multiple buildings or facilities, thereby lacking the direct connection associated with proprietary systems. Local alarm systems operate independently within a single location, providing alerting capabilities without direct monitoring or oversight by an off-site agency or owner. While all these systems serve critical roles in safety and emergency response, proprietary systems specifically denote ownership and direct connectivity by the building's owner.
