Nest Protect has been completely redesigned. It has an industrial-grade smoke sensor, can be hushed from your phone, test itself automatically, and last up to 10 years. It also tells you what's wrong and can even alert your phone.

• Sends alerts to you phone in case you aren't home
• Split-spectrum sensor detects fast and slow burning fires
• First alarm you can silence from your phone
• Speaks up to tell you what's wrong and where is the problem
• Keeps you safe and sound for up to 10 years, longest allowed by law
• Can see the poisonous carbon monoxide you can't
• Test it over 400 times a day and you can check the status in the Nest application
• Looks for steam to cut down on false alarms from a long shower
• When you walk underneath it at night, path light will light your way
• A green glow when you turn off the lights means no low-battery chirps at 2 am
• Wink App Ready - No Wink Hub Required

SPECIFICATIONS

The National Fire Protection Association (NFPA) and the Consumer Product Safety Commission (CPSC) recommend several places to place a smoke and carbon monoxide alarm.

• Inside and outside every sleeping area
  
  If you close your bedroom door before you go to sleep, make sure you install a smoke alarm inside your bedroom and in the hallway. Closed or metal doors can also block smoke from reaching a smoke alarm.
  
  The Consumer Product Safety Commission suggests that each home should have a carbon monoxide alarm near each bedroom as well as every separate sleeping area. Most local state codes now require at least one carbon monoxide alarm for residential homes.
  
• On every floor, including finished attics and basements
  
  Most state residential building codes require a smoke alarm on every level for your own protection. In homes with more than 1,000 sq. feet on one level, additional alarms may be required.
  
• At the top of a first-to-second floor stairway
  
  In multi-story homes, a fire on one level can grow to dangerous levels before smoke has the chance to rise in a stairway.
  
• On a basement ceiling near the stair entry

Are there any rooms where installing a smoke and carbon monoxide alarm is not recommended?

Some rooms in your home have conditions that are more likely to damage a smoke and carbon monoxide alarm or set off nuisance alarms.

Regulations recommend against installing combination smoke/carbon monoxide alarms in these rooms:

• Kitchens
  
  If you want, you can install Nest Protect closer to cooking appliances than conventional smoke alarms. However, regulations suggest you place it at least 10 feet (3 meters), from cooktops or cooking appliances.
  
• Unfinished attics
  
  Smoke alarms are not designed to work in extreme heat or cold, or in areas where smoke and dust are common as it could damage the sensors of the alarm.
  
• Garages
  
  As they are usually not heated or cooled, the actual temperatures experienced in a garage may go above or below the temperature range that the alarm has been designed for. The smoke from engine exhaust fumes can also cause nuisance alarms and damage the sensors of the smoke alarm.
  
• Furnace rooms, or any room that contains a water heater or a furnace.
  
  To avoid nuisance alarms, carbon monoxide alarms should be 15-20 feet from water heaters or furnaces.
  

Can I just replace my existing smoke and carbon monoxide alarms?

Although you may have existing alarms in your home, check the placement of those alarms for compliance with these or local guidelines. Older homes, especially, may not align with current regulations.
