Can anybody tell me the what the minimum dB readings can be in an area with fire alarm sounders, I know the actuall sounder must comply to a minimum standard but is there such a level for the surrounding area? Thank you for your help.

In most areas you want the sound pressure level to be 65dB(A), but there are a few exceptions where 60dB(A) is OK such as stairways, specific points and areas less than 60m2.

Where there is background noise or where people sleep there are other recommendations.

See BS 5839-1:2002 for full details.
