Does an exterior horn for a sprinkler system need to be supervised?

In fire alarm and signaling systems, supervision is a key aspect to ensure reliability and immediate response during emergencies. When it comes to exterior horns for a sprinkler system, they play a critical role in communicating to occupants and emergency responders that a fire condition exists and that evacuations may be necessary. Supervision of these horns ensures that they are operational and capable of functioning when needed.

In accordance with the NFPA 72 Code, all components of fire alarm systems that are intended to alert occupants or provide signals in the event of a fire must be supervised to ensure they are not in a state that could prevent them from operating. This includes any signalling devices, like exterior horns, which must be monitored for potential failures, such as loss of power or physical damage. This oversight ensures that if an alarm situation arises, the exterior horns will perform as intended, thereby enhancing the overall safety of the environment.

Overall, the requirement for supervision helps maintain the integrity of the fire alarm and sprinkler system, reducing the risk of failure in critical conditions.
