The National Fire Protection Agency (NFPA) recently updated the Standard for the inspection, testing, and maintenance of water-based fire protection systems. NFPA 25 now requires that glycerin and propylene glycol antifreeze solutions currently used in installed fire sprinkler systems be replaced with a listed antifreeze solution by September 30, 2022.

Until very recently, there was no listed antifreeze solution available to use. However, now that a listed product is available, Alarm Detection Systems (ADS) would like to inform you that you have an antifreeze system that will need to be drained and refilled with the new solution. Only a licensed sprinkler contractor can provide this service.
