After initial installation, it is recommended to go for at least one full annual test as well as inspection. Testing intervals are recommended, and in some circumstances, mandated, by various agencies, organizations, and municipal governments.
The National Fire Alarm Code, NFPA 72, is published by the National Fire Protection Association (NFPA) which involves installation, maintenance, and various other aspects.
Inspection, testing, and maintenance are covered in Chapter 7. A table in the document talks about the generators, batteries, interface devices, as well as other aspects of fire protection service management software.
With this thorough inspection they will generate a fire extinguisher inspection report to tell you if there is any need for replacement or reinstalling it to a more appropriate place.
Different extinguishers from different companies have their own time interval for inspection.
It is highly recommended that you get the extinguishers checked at least once a year for annual testing and maintenance to stay sure.
They will inspect the extinguisher nameplate, with the proper operating instructions.
Also, the nameplate and instructions should be facing outwards.
