Overview
A renter or homeowner who wants a smoke alarm without yearly battery changes gets a slim photoelectric detector powered by a long life battery. A test and reset button checks the alarm and silences it after a false trigger.
Low maintenance is the reason to buy, with a battery built to last the life of the alarm. Interconnection, voice alerts and mounting hardware are not described, so it suits single room protection.
Who it's for
Apartments, bedrooms and hallways that need simple, independent smoke alarms get a slim, low maintenance unit. Larger homes where every alarm should sound together need an interconnected system.
Pros and cons
- Long life battery

Performance notes
A photoelectric sensor shines light across a chamber and alarms when smoke particles scatter it, which responds well to smoldering fires. A sealed long life battery removes the most common failure, a missing or dead battery.
