For compliance with NFPA 13, what must be ensured about system controls?

In NFPA 13, it is essential to ensure that system controls are regularly monitored and maintained to guarantee their functionality and reliability in a fire protection system. This practice is crucial because fire sprinkler systems must respond appropriately during an emergency situation, and consistent maintenance is necessary to ensure that all components, including system controls, are in working order.

Regular monitoring involves routine checks and assessments to identify any potential malfunctions or areas that could affect system performance. Maintenance activities can include testing alarms, inspecting valves and control panels, and verifying that all system components are operating as intended. This proactive approach ensures compliance with NFPA 13 standards, enhances the overall safety of the installation, and mitigates risks associated with fire hazards.

In contrast, neglecting the system controls or only testing them during annual reviews could lead to overlooked deficiencies that might compromise the system's effectiveness in an emergency. Custom designs for every installation are not a requirement under NFPA 13, as many systems can be tailored using standardized procedures and components that meet the necessary performance criteria.
