I called to schedule the semi annual fire suppression service on the kitchen Ansul System. I was going to be in that area and wanted to get it on my schedule. I talked with management and they let me know that would work for them. I then arrived and did the initial inspection of the fire system. I did not see any defects so I put the system in test mode. I put a test link in and tested it for the ability to work when needed. I did not find any defects so I put new fusible links in and put the caps back on. I put the system back to operational mode. I wrote the report and let them know I would be back in 6 months to re-inspect the system per NFPA code.
