What type of fire alarm system signals the need to evacuate?

The general alarm system is specifically designed to signal an immediate need to evacuate a space or vessel during an emergency situation, such as a fire. This system typically employs loud, distinctive alarms or signals that are easily recognizable to alert all personnel on board. The urgency conveyed by a general alarm prompts immediate action to ensure safety and compliance during evacuations.

Unlike a localized alarm system, which may indicate danger in a specific area without necessarily requiring a full evacuation, the general alarm is intended to reach all occupants of the vessel. A standard notification system may provide notifications of various hazards but does not always indicate the urgent need to evacuate. Meanwhile, a silent alarm system is typically used to discreetly notify security or monitoring personnel of an issue without alarming everyone, which does not promote the necessary immediate evacuation response. The primary purpose of a general alarm system is to ensure that everyone understands the critical nature of the situation and takes appropriate action to evacuate promptly.
