For this reason, it is recommended that the householder consider the use of additional smoke alarms for those areas for increased protection. The additional areas include: basement, bedrooms, dining room, furnace room, utility room and hallways not protected by the requiredsmoke alarms. The installation of smoke alarms in kitchens, attics (finished or unfinished), or garages is notnormally recommended, as these locationsoccasionally experience conditions that can result inimproper operation. Figure 3: A SMOKE ALARM SHOULD BE LOCATED ON EACH STORY. IMPORTANT CONSIDERATION We recommend replacing your alarm(s) every ten (10) years; why: · Dust, dirt, and other environmental contaminants can affect your alarm over a prolonged period. · Fast changing industry consensus standards and codes on all alarms make it advisable to periodically upgradeyour alarm to maximize life safety. · Assurance that your smoke alarm needs are kept abreast with the constantly improving electronictechnology. · Smoke alarms are recognized as one of the lowest cost ways to protect dwelling inhabitants against the dangerof fire(s). It makes good common sense to periodically replace and update your smoke alarm that contributesso much to life safety. MOUNTING LOCATION · Wall location-locate the top of the alarm at least 4 inches and not more than 12 inches from the ceiling. Observe alarm for proper top/bottom orientation (test knob is near bottom of unit). Figure 4: RECOMMENDED SMOKE ALARM MOUNTING LOCATIONS Pg. 7-3 WHERE SMOKE ALARMS SHOULD BE PUT IN MOBILE HOMES In mobile homes built after about 1978 that were designed and insulated to be energy-efficient, smokealarms should be installed as described in the section above. In older mobile homes that have little or no insulation compared to today's standards, uninsulated metal outsidewalls and roofs can transfer heat and cold from outdoors, making the air right next to them hotter or colder than therest of the inside air. These layers of hotter or colder aircan prevent smoke from reaching a smoke alarm. Therefore, put smoke alarms in such units only on insidewalls, between 4 and 12 inches (10 and 30 cm) from theceiling. If you are not sure about the insulation level inyour mobile home, or if you notice that the walls or ceilingare unusually hot or cold, put the alarm on an inside wall. Minimum protection requires one alarm as close to thesleeping area as possible. For better protection, put onealarm in each room, but first read the "Locations to Avoid." LOCATIONS TO AVOID Nuisance alarms are caused by placing alarms wherethey will not operate properly. To avoid nuisance alarms, do not place alarms: · In or near areas where combustion particles are normally present such as kitchens; in garages where there are particles of combustion in vehicle exhausts; near furnaces, hot water heaters, or gas space heaters. Install alarms at least 20 feet (6 meters) away from kitchens and other areas wherecombustion particles are normally present. · In air streams passing by kitchens. Figure 5 shows how an alarm can be exposed to combustion particlesin normal air movement paths, and how to correct thissituation. Figure 5 · In damp or very humid areas, or next to bathrooms with showers. The moisture in humid air can enter the sensing chamber as water vapor, then cool andcondense into droplets that cause a nuisance alarm. Install alarms at least 10 feet (3 meters) away frombathrooms. · In very cold or very hot environments, or in unheated buildings or outdoor rooms, where the temperature can go below or above the operatingrange of the alarm. Temperature limits for properoperation are 40° to 100°F (4.4° to 37.8°C). · In very dusty or dirty areas. Dust and dirt can build up on the alarm's sensing chamber and can make itoverly sensitive, or block openings to the sensingchamber and keep the alarm from sensing smoke. · Near fresh air inlets or returns or excessively drafty areas. Air conditioners, heaters, fans, and fresh air intakes and returns can drive smoke awayfrom smoke alarms, making the alarms less effective. · In dead air spaces at the top of a peaked roof or in the corners between ceilings and walls. Dead air may prevent smoke from reaching an alarm. · In insect-infested areas. If insects enter an alarm's sensing chamber, they may cause a nuisance alarm. Get rid of the bugs before installing alarms where bugs are a problem. · Near fluorescent light fixtures. Electrical "noise" from nearby fluorescent light fixtures may cause anuisance alarm. Install alarms and fluorescent lights on separate electrical circuits. WARNING: Never disconnect an AC alarm to silence a nuisance alarm. Open a window or fan the air around thealarm to remove the smoke. The alarm will automaticallyturn off when the smoke in the air is completely gone. Do not stand close to the alarm. The sound produced by thealarm is loud because it is designed to awaken you in an emergency. Prolonged exposure to the horn at a closedistance may be h...
