The customer called for a semi-annual inspection of their kitchen Amerex fire suppression system. I scheduled the appointment and arrived to do the service for them. I took the system offline and inspected each component of the system. I found no major defects or problems. I changed the fusible links and the low temp caps of the nozzles. I put the system back to operational mode and wrote a report for the customer. I let them know their next visit would be in 6 months.
