First Alert Onelink allows wireless smoke detector integration.  120VAC hardwired wireless detectors interconnect alarms with battery backup.  Expand protection to include  existing hardwired detectors and new wireless detectors by replacing one existing hardwired alarm with Onelink. By adding Onelink battery operated alarms elsewhere, when one alarm sounds in either series of alarms, all alarms will be notified.  Easily link alarms together with the press of a button. Photoelectric smoke sensor reduces nuisance alarms from cooking smoke or shower steam.  Easy access battery drawer: no need to remove alarm from ceiling to change battery. 10-year limited warranty. Meets UL standards.

 

This is the perfect smoke alarm for you if:

you want to build a safety network of integrated detectors in your home without the cost and hassle of wiring

you want battery operated photoelectric sensor smoke detectors to reduce nuisance alarms

you want to mute unwanted alarms with the press of a button

you want battery operated reliability that protects your family and the environment

 

Place one smoke alarm in each bedroom, and at least one on every level of the home.
