What is the purpose of a fire alarm relay?

The purpose of a fire alarm relay is to connect the fire alarm system to other building systems, facilitating communication and coordination during an emergency. This connection allows the fire alarm to interact with various other systems in the building, such as HVAC systems, emergency lighting, or security systems. For example, when a fire alarm is triggered, a relay can signal the HVAC system to shut down to prevent smoke from spreading, or it can activate emergency exit lighting to guide occupants safely out of the building.

Integrating the fire alarm system with other building systems enhances the overall safety measures in place and ensures a more comprehensive emergency response. This function is crucial for maintaining situational awareness and effectively managing life safety in the event of a fire.
