How often should the sprinkler system's alarm test valve be inspected?

The inspection of the sprinkler system's alarm test valve is required on an annual basis to ensure that it operates correctly and efficiently in the event of a fire. Annual inspections help to verify that the valve is not obstructed and that it will function as intended when needed. This frequency allows for adequate monitoring of the system's components, ensuring any necessary maintenance or repairs can be made in a timely fashion. Regular checks contribute to overall safety and compliance with fire codes and standards. Other frequencies, such as monthly or biannual inspections, may not provide sufficient assurance regarding the system's reliability, while a five-year interval would likely be too long to ensure proper functioning of critical alarm components.
