Which alarm system is monitored by a central alarm receiving point staffed by personnel?

• A. Proprietary
• B. Central Station
• C. Local
• D. Auxiliary

Answer: (B)

The key idea is how alarms are monitored. A central alarm receiving point staffed by personnel describes an off-site monitoring service where trained operators at a central station continuously watch for alarm signals, verify them, and coordinate response. That directly matches the definition of a central station system.

Local systems sound and alert on the premises only, with no remote monitoring. Proprietary systems are monitored by the organization’s own staff or a monitored center you control, which isn’t the external central receiving point described here. Auxiliary refers to support functions or non-fire aspects rather than the monitoring arrangement itself.
