Which type of alarm system is used to protect large commercial and industrial facilities and is connected to a common receiving point somewhere on the facility?

• A. Local Alarm System
• B. Central Station Alarm System
• C. Remote Monitoring System
• D. Proprietary Alarm System

Answer: (D)

A proprietary alarm system is designed for large facilities and is owned and operated by the facility itself. It includes a central receiving point located somewhere on the site, allowing internal staff or the site’s fire/safety team to monitor, coordinate responses, and integrate with other building systems. This on-site control and monitoring fit the scenario of protecting a large commercial or industrial facility with a common receiving point within the facility. Local alarms only sound on site, central station and remote monitoring involve third-party off-site centers, so they don’t match the described on-site receiving point.
