In NFPA 72, which type of alarm system is designed to send signals directly to the fire department?

The "direct connection" alarm system is specifically designed to send signals directly to the fire department when an alarm is triggered. This system enhances response times in emergency situations because it allows for immediate notification of the fire department, facilitating quick action in response to a potential fire hazard.

In NFPA 72, a direct connection typically refers to a system that is linked straight to the fire department or a central station that has the ability to alert the fire department without any intermediary steps. This type of system is often required in certain high-risk building types and in jurisdictions where rapid response is critical.

Manual alarm systems involve human intervention to activate an alarm, which may introduce delays in notifying emergency services. Automated alert systems and monitoring alarm systems usually operate through a chain of communication that may require additional steps before informing the fire department, which can slow down the response. Therefore, the direct connection is distinct in ensuring immediate and direct communication with emergency responders.
