• Do install smoke alarms in both rooms (areas) that are divided by a partial wall extending 24 or more inches down from the ceiling. See smoke alarms located in rooms B and C in Figure 4. SPECIAL DIRECTIONS FOR INSTALLING YOUR SMOKE ALARM IN MANUFACTURED AND MOBILE HOMES WARNING: SMOKE ALARMS MAY BE INSTALLED ON THE CEILINGS OF MANUFACTURED AND MOBILE HOMES IF THERE IS ADEQUATE INSULATION IN THE CEILING. Install smoke alarms on walls only between 4 and 12 inches from the ceiling. Install smoke alarms on inside walls in older homes or in homes where you are not sure of the insulation level. In older homes (manufactured in approximately 1976 or before) that have little or no insulation compared to today’s standards, uninsulated metal outside walls and roofs can transfer heat and cold from the outdoors, making the air right next to the wall or roof hot or cold, compared to the rest of the air inside the room. These layers of hot or cold air can prevent smoke from reaching a smoke alarm. If your mobile home has this condition, put your smoke alarm on an inside wall only, between 4 and 12 inches from the ceiling. If you are not sure about the insulation in your mobile home or if you notice the outside walls or ceiling are unusually hot or cold, put the smoke alarm on an inside wall. 3 MOBILE HOME EFFICIENCY APARTMENT FIGURE 5: EFFICIENCY APARTMENT AND MOBILE HOME INSTALLATION WHERE YOU SHOULD NOT INSTALL SMOKE ALARMS • Do not install a smoke alarm within close proximity of heating and cooling supply vents or within close proximity of return or fresh air vents. Smoke may be blown away from the smoke alarm by the supply vents, or could be diffused or reduced by being diverted into the return air vent. The NFPA states in Standard 72E, Section 4-4.1: “In rooms, buildings, where forced ventilation is present, detectors shall not be located where air from supply diffusers (“vents”) could dilute smoke before it reaches the detector.” • Do not install your smoke alarm in an area where the temperature may fall below 40°F, or rise above 100°F. Smoke alarms are designed to work safely only within these temperature ranges, and failure to alarm, improper alarms or nuisance alarms may result from operation outside these temperature limits. • Do not install a smoke alarm in damp or very humid areas such as bathrooms with showers, where the normal humidity may rise above 93% relative humidity. Above this level, moisture may condense inside the smoke chamber and cause false alarms. • Do not install a smoke alarm in an area where particles of combustion are normally present, such as kitchens or automobile garages, unless the smoke alarm has a False Alarm Control feature. • Do not install a smoke alarm in dusty or dirty areas; SUCH AN INSTALLATION CANNOT BE RELIED UPON. An accumulation of dust and dirt in the sensing chamber may block the openings and prevent an alarm, or may get inside the alarm and cause false alarms. If a smoke alarm is required in such an area, vacuum it frequently and test it according to the section “TAKING CARE OF YOUR SMOKE ALARM.” • Do not install a smoke alarm in the dead air space in the corner where the wall meets the ceiling. If in doubt as to the exact location of mounting, for your safety, contact your local fire department for help in choosing a location. • Do not install a smoke alarm where bugs or insects are present before eliminating or minimizing the bug problem. Although all smoke alarms built since 1986 are made to help prevent bugs from entering the detection chamber, bugs may build up on chamber openings and prevent smoke from entering. As a result, unit should be vacuumed frequently as explained in the section “TAKING CARE OF YOUR SMOKE ALARM.” • Do not install a smoke alarm within close proximity of a fluorescent light. Electrical noise may cause nuisance alarms. HOW TO INSTALL YOUR SMOKE ALARM AFTER HAVING CAREFULLY READ THE FIRST FIVE SECTIONS OF THIS MANUAL, YOU ARE READY TO INSTALL YOUR SMOKE ALARM. PLEASE FOLLOW THESE DIRECTIONS: 1. Unlock and remove mounting bracket from smoke alarm with a counterclockwise twist. 2. Place mounting bracket on ceiling or wall in prearranged location and use pencil to trace two opposing hole positions for mounting screws. Drill two 1/16-inch holes. 3. Use mounting screws provided for attaching to studs or woodwork. For plaster or plasterboard, you may wish to use plastic anchors and screws. See Figure 6. 4. Screw mounting bracket to surface securely. NOTE: Before mounting alarm on a wall, be sure arrow on mounting bracket is pointing up toward ceiling. See Figure 6. 5. Install battery. (See “REPLACING THE BATTERY”) 6. Attach smoke alarm to mounting bracket with a clockwise twist until it snaps into locked position. NOTE: Your smoke alarm is designed with a safety mechanism that prevents mounting unless a battery is installed. This helps ensure the alarm is functional when mounted. 7. You have now finished installing your smoke alarm. For your safety,...
