Which fire alarm system sends a signal directly to the fire department or another monitoring location?

The option that sends a signal directly to the fire department or another monitoring location is the remote station systems. These systems are designed to provide immediate notification to emergency services in the event of a fire alarm. When a fire alarm is triggered, the signal bypasses any local alarms and is transmitted directly to the appropriate authorities, such as the fire department, ensuring a swift response.

In contrast, local alarm systems are intended mainly for use in individual buildings and notify only occupants through audible alarms, without direct external notification. Auxiliary systems serve to support the main fire alarm systems but do not necessarily facilitate direct communication with the fire department. Proprietary systems may be designed for specific private entities and typically require a comprehensive setup for monitoring but are not standardized for direct connection to fire departments as remote station systems are. This makes remote station systems crucial for ensuring that emergency responders are alerted promptly, enhancing overall safety and response times during fire emergencies.
