Final answer:
A continuously manned alarm control center must include central monitoring of alarms and the ability to dispatch a response force. Local alarms are not considered acceptable.
Step-by-step explanation:
A continuously manned alarm control center must include central monitoring of alarms and the ability to dispatch a response force. Local alarms, such as alarm bells located only at the protected location, are not considered acceptable because they may not provide a timely response in case of an emergency. Instead, a continuously manned alarm control center should have a system in place to monitor alarms from various locations and ensure a prompt and coordinated response to any potential danger.
