- Page 2 •Install smoke detectors at both ends of a bedroom hallway if the hallway is more than 40 feet (12 meters) long. •Install a smoke detector inside every room where one sleeps with the door partly or completely closed, since smoke could be blocked by the closed door and a hallway alarm may not wake up the sleeper if the door is closed.
