Why is no annual maintenance required on the Firechief® Kitchen Stove Guard?

The Firechief® Kitchen Stove Guard contains an automatic fault diagnosis system

Automatic fault diagnosis constantly analyses the Kitchen Stove Guard’s function when the hob is in use.

This means no monthly testing or annual maintenance is necessary.

The Stove Guard sensor’s battery has a 10-year life, and the product has a 2-year warranty.
