Excessive smoke alarms….

Hi,

We have excessive smoke alarms in our Lots. For example my 2 bedroom Lot has four (yes 4!) alarms.  I am all for safety and abiding by legislation but there is definitely an overkill here.

In a Department of Planning document it states a building classified as a level 2 only requires one smoke alarm per level flooring. We are a level 2 building, registered in 2007, mixed scheme use of 42 lots and 1 commercial in NSW.

Rather than rely on the S/M’s “understanding” or vague “interpretation ” and the fire companies “recommendations” can anyone give me specific directions here including building codes or legislative requirements – please? 

Also do these unnecessary smoke alarms now form common property.  Why do we need to maintain 4 alarms when 1 would suffice and that’s what the law states?
