First Alert OneLink Wireless Battery Powered Smoke Alarm with Voice

The First Alert (SA511B) eases the time, labor, and investment to retrofit hardwired alarms. Now with its patented OneLink technology, Wireless interconnect technology eliminates the need to pull wires through existing walls, saving you an average of between $150 - $200** per alarm when compared to retrofitting hardwired smoke alarms in existing walls or ceilings. First Alert, together with BRK brand alarms, continue to reinvest in the research and development of Smoke Alarm Safety Products.
