Customer called and wanted to get the Fire Suppression system on the schedule. I was able to fit that into my schedule on the 2nd. I arrived and started prepping the system. I took out the old parts and added new parts (fusible links) and then tested to make sure everything was working and also looked for any thing that would stop it from working. I then did an inspection of the dampers in the duct system. Everything is in good working order. I then put the system back online and they are good for another 6 months.
