I wonder how many home owners will get new smoke alarms to comply with this. I heard the fine is about $150 but they aren't going to inspect homes.http://www.cityofmadison.com/news/view.cfm?news_id=2158
Under the ordinance passed last year, all smoke alarms must have a 10-year lithium battery in a tamper-resistant alarm unit. 9-volt batteries will no longer be used UNLESS they are being used as a battery back-up to a hard-wired alarm.
The ordinance also requires additional alarms in the residence:
-In each bedroom
-In each sleeping area
-Within six feet of each door leading to a bedroom or sleeping area of each unit
-On each floor of the building
