WiFi carbon monoxide and smoke alarm.
For maximum protection, we recommend installing an alarm on every floor of a multi-story home, including every bedroom, hallway, finished attic and basement.
If the hallway or room is longer than 30 feet (9.1 meters), install alarms at each end of the bedroom hallway or large room.
If you only have one alarm, be sure to install it in the hallway or in the main bedroom outside the main sleeping area.
