Smoke Detectors in Maryland (Frederick) - AC vs battery operated

[Andrey Y.]

I am in the process of preparing my Frederick property for the tenant. My real estate agent who uses zipLogix rental lease is trying to convince me that I HAVE to use the dual powered (AC and battery) smoke detector.

The lease is referring to § 9-102. Smoke alarms required in sleeping areas law. The § 9-102 refers to NFPA 101: Life Safety Code as adopted by the State Fire Prevention Commission. Eventually after drilling down through Maryland laws I do not see any mention of the dual powered smoke detectors requirements.

So I figured that BP might help me.

Thanks a lot !!!
