What are the requirements for the pump running signal in a low-rise residential building with a required fire alarm system?

In a low-rise residential building with a required fire alarm system, the pump running signal must convey the operation status of the fire pump effectively. A pump running signal is essential for indicating that the fire pump is actively operating to provide water for fire suppression.

This signal can fall into two categories: supervisory or alarm. As a supervisory signal, it informs the monitoring station or firefighters that the pump is functioning, which is crucial for maintaining readiness in fire response scenarios. If the pump is running during a fire event, it may also serve as an alarm signal, alerting occupants or emergency services to the operational status of the system, thereby ensuring safety measures are in place.

Consequently, the requirement for the pump running signal being classified as either a supervisory or alarm signal ensures flexibility and responsiveness in the fire alarm system's monitoring and operational protocols. It allows for effective communication of the pump's status, which is vital for ensuring that fire suppression systems are reliable and can function when needed.
