First Alert Wireless Interconnected Photoelectric Smoke and Carbon Monoxide Combo Alarm with Voice and Location, SCO500B-3
Protect your family from harm with this First Alert battery-powered smoke and carbon monoxide detector. Photoelectric smoke sensing technology detects slow, smoky and smoldering fires and reduces nuisance alarms caused by shower steam or cooking smoke. This detector also alerts you at the first sign of carbon monoxide, helping you avoid exposure to potentially fatal gas. The voice and location feature notifies you of danger’s origin, so you can easily avoid unsafe areas. It also tirelessly interconnects with other detectors in your home, so that when one alarm is triggered all detectors will sound. A front-load door makes battery replacements a breeze, allowing you to keep your loved ones safe at all times.

First Alert SA511CN2-3ST Wireless Interconnected Smoke Alarm with Voice Location, Battery Operated, 2 Pack
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. A photoelectric sensor detects smoke while minimizing false alarms from cooking or shower steam. Interconnected smoke detectors in different locations are designed to work together, with one alarm triggering the other alarm during a fire, helping to provide the earliest warning for your family.
In the event of a fire every second counts. If a fire were to begin in your basement and the alarm there sounded, you may not hear it right away if you’re sound asleep two floors up. With traditional battery-operated alarms, you lose valuable time waiting for the smoke to rise to another alarm, on another level, before the alarm on your floor sounds. But with First Alert ONELINK alarms, if one detects danger, they all sound. This can alert you sooner, and it increases your chances of getting out safely. Until now, alarms that could signal each other were only available in homes with hardwired alarms requiring installation from an electrician. But First Alert ONELINK alarms communicate without wires. ONE Link-with Voice Location Smoke alarm is programmable with up to 11 locations in your home – when alarm sounds it will tell you the location of the smoke. The wireless feature allows multiple alarms to talk to each other – when one alarm sounds, they all sound. The wireless network operates on 914 MHZ 3 channels and will not interfere with other electronics. The ONELINK smoke alarms uses photoelectric sensing technology which is environmentally friendlier and which reduces nuisance alarms, making it ideal for cooking areas. It is also great for sensing slow smoldering fires quickly. A low battery signal alerts you to replace the battery. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit’s functionality. The AA batteries are easy to install in the convenient pullout battery drawer. Two AA batteries included.
