Routine AOV testing

[Guest Dave]

Hi 

can you point me to a British standard or other guidance document as to what frequency I should routinely test an AOV system. 

Thanks

BS9999:2017 gives a useful PPM regime for most fire protection systems in a building - saves looking at loads of individual standards.

Usually AOV's are tested for operation weekly and a full service of batteries, motors, chains, etc annually.
