" How to Install Smoke Detectors  Having working detectors in your home can be a literal lifesaver: You are twice as likely to die in a house fire if you have none. Fumes from a smoldering fire can build up overnight as you sleep, so a smoke alarm may be your first and only warning. You&amp;#039;ll Need: Smoke or Carbon-Monoxide Detectors, with Hardware Multipurpose Detector, If Needed Batteries, If Needed Scratch Awl or Nail Power Drill, with Appropriate Bits for Wall Type or Ceiling Suitable Anchors for Wall Type or Ceiling, If Needed Screwdriver Getting Started: Decide which type of detector you need. Be sure to look for one that is UL-listed. Your detector can be batteryoperated, hard-wired, or a combination of both. Others simply plug in to existing standard electrical outlets. Ionization smoke detector: the cheapest to buy. This will go off when it senses small smoke particles from flaming fires, such as from a frying pan or burning food. Carbon-monoxide detector: essential if you have any appliance that uses gas, oil, wood, or coal. Even water heaters, furnaces, and well-controlled open fires or log burners can be killers. If they aren&amp;#039;t burning efficiently or the room isn&amp;#039;t well ventilated, they can produce the lethal gas carbon monoxide, which is undetectable until it&amp;#039;s too late. Combined detector: Buy combined smoke and carbon-monoxide detectorsand you&amp;#039;re covered for both types of danger.  Decide where to position your detectors. In kitchens, the National Fire Protection Association recommends that they be positioned 10 feet away from cooking appliances. Install detectors within 15 feet of sleeping areas so that everyone can hear the alarm if it goes off\u2014even if their doors are closed. Single-story homes: in hallway, between sleeping and living areas. Ideally place on ceiling, at least 12 inches away from wall or light fixture. On inside walls, place 6-12 inches lower than ceiling height. Large or multistory homes: as above, plus at bottom of staircase and on each staircase landing. Also consider buying interconnected alarms so that smoke or heat detected on one level can trigger alarms all over the house. Homes with real fires or natural gas supply: as above, with additional carbon-monoxide alarm. If you are using a combination smoke alarm, fit as smoke alarm. Otherwise, fit in same room as appliance or somewhere central (hallway, landing), at head height, at least one yard from furnace, fire, or heater and not directly above anything that gives off steam. What to do: 1. Locate best position for alarms (see Getting Started). Use a multipurpose detector to find positions of hidden pipes and cables and avoid drilling there. Unless wall is masonry, locate studs using a detector and attach to these, if possible. 2. Remove cover of alarm and install batteries, if needed, following manufacturer&amp;#039;s instructions. 3. Hold back plate to wall or ceiling and mark screw points with scratch awl or nail through holes. 4. Drill holes to depth of anchors, if using, and push in. If attaching to studs or rafters, drill pilot holes. 5. Screw the alarm in position. Replace cover and test. How to Nail it:  Check your alarm batteries regularly and replace any dead batteries immediately (usually after 12 months). Always recycle used batteries.  If you are worried about losing battery power, you can find alarms that wire into the electricity supply (backed up by batteries).
