Nest Protect is designed to detect smoke and carbon monoxide in a residential environment.
It has multiple sensors to help it understand what’s happening in your home and a photoelectric
sensor to detect slow, smoldering fires. Nest Protect can be used as a single station or multiple
station alarm.

Wi-Fi, an iOS or Android smartphone or tablet, and a free Nest Account are required for wireless
mobile notifications and software updates. During set up, Wi-Fi and a free Nest Account are
required for wireless interconnect and room naming. After all the Nest Protects in your home
are connected, they can communicate with each other without Wi-Fi.

The National Fire Protection Association recommends installing a smoke alarm in the following areas:
• On every floor, including finished attics and basements.
• Inside and outside every sleeping area.
• At the top of the first-to-second floor stairway and on the basement ceiling near the entry
of the stairs.
• In homes with more than 1,000 square feet on one level, additional alarms may be required.
Nest Protect should be installed at least 10 ft (3 m) away from cooktops or cooking appliances.
Nest Protect should NOT be installed in unfinished attics or garages.
