Topic: Fire Supression System Certificaiton

We have an AFFF 4 liter mechanically-actuated system from Spa Technique installed in our car. We bought it about 3 years ago, so its past the "2 year service date".

Is the 2 year service required to maintain FIA certification, even if the bottle shows a full charge?

Is this treated like a nomex suit that is certified "forever" (unless obviously compromised), or is it treated like belts that have an expiration date.

The rules say:

LeMons EXCEEDINGLY STRONGLY recommends a properly plumbed, fully charged, securely mounted SFI- or FIA-certified onboard fire suppression system with agent-appropriate nozzles
