The First Alert interconnected wireless smoke alarm with voice location is designed to notify you of trouble with both an 85 dB siren and voice notification. The battery-operated unit can be installed easily, without wires or an electrician. The units communicate tirelessly with each other and sound the alarm together, providing an efficient and comprehensive warning solution for large areas or homes with multiple stories. The smoke detector features a photoelectric sensor designed to sense smoke but minimize the number of false alarms due to cooking smoke or shower steam.
