Do interconnected smoke alarms need to be hardwired?
Interconnected smoke alarms are either hard-wired or wirelessly interconnected and powered by a ten-year lithium battery. Hard-wired smoke alarms must only be installed by a professional electrician.
Do wireless interconnected smoke detectors meet code?
Like wired smoke detection systems, wireless smoke detectors are code compliant when they meet NFPA standards. The NFPA 72 sets out certain requirements for wireless smoke detector manufacturing, installation and testing which must be met in order to be code compliant.
How long do interconnected smoke alarms last?
