Indianapolis-Marion County:

In new construction, smoke alarms must be installed in each sleeping room and be arranged so that operation of any smoke alarm causes all smoke alarms to sound. If the alarm is solely powered by a battery, the battery must be non-removable, non-replaceable and capable of powering the alarm for a minimum of 10 years. Battery-operated alarms connected to a panel or using low-power wireless communication signals are exempt from this battery requirement.
