The First Alert SA511CN2-3ST Interconnected Wireless Smoke Alarm with Voice Location features an 85-decibel siren and voice alarm that tells you where the danger is located. The smoke detectors are interconnected and communicate wirelessly, so when one unit sounds an alarm, they all go off to alert you of potential danger. The photoelectric sensor is designed to be sensitive to smoke while reducing false alarms from cooking smoke or shower steam. The smoke detector requires two AA batteries and can be installed easily with no electrician or hardwiring needed.
