- Page 2 >Install a smoke detector inside every bedroom. >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.
- Page 3 > Dead air spaces are often at the top of a peaked roof, or in the corners between ceilings and walls. Dead air may prevent smoke from reaching a detector. > In insect-infested areas. If insects enter a detector’s sensing chamber, they may cause a nuisance alarm. Where bugs are a problem, get rid of them before putting up a detector.
- Page 4 WARNING: Never use an open flame to test your detector. You may set fire to damage the detector, as well as your home. The built-in test switch accurately tests all detector functions, as required by Underwriters’ Laboratories. They are the only correct ways to test the unit. WARNING:When you are not testing the unit and the alarm horn sounds a loud continuous sound, this means the detector has sensed smoke or combustion particles in the air.Be sure that the alarm horn is a warning of a possible serious situation, which requires your immediate attention.
