FIGURE 1 FIGURE 2 FIGURE 3 MOBILE HOME INSTALLATION Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as recommended above (refer to RECOMMENDED LOCATIONS and FIGURES 1 and 2). In older mobile homes that are not well insulated compared to present standards, extreme heat or cold can be transferred from the outside to the inside through poorly insulated walls and roof. This may create a thermal barrier which can prevent the smoke from reaching an alarm mounted on the ceiling. In such units, install the smoke alarm on an inside wall with the top edge of the alarm at a minimum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the ceiling (see FIGURE 1). If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and ceiling are either hot or cold, install the alarm on an inside wall. For minimum protection, install at least one alarm close to the bedrooms. For additional protection, see SINGLE FLOOR PLAN in FIGURE 2. WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER R.V. OR MOBILE HOME VEHICLE HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE A WEEK DURING USE. 2. LOCATIONS TO AVOID • In the garage. Products of combustion are present when you start your automobile. • Less than 4” (10cm) from the peak of an “A” frame type ceiling. • In an area where the temperature may fall below 40.F or rise above 100.F, such as garages and unfinished attics. • In dusty areas. Dust particles may cause nuisance alarm or failure to alarm. • In very humid areas. Moisture or steam can cause nuisance alarms. • In insect-infested areas. • Smoke alarms should not be installed within 3 ft (.9m) of the following: the door to a kitchen, the door to a bathroom containing a tub or shower, forced air supply ducts used for heating or cooling, ceiling or whole house ventilating fans, or other high air flow areas. • Kitchens. Normal cooking may cause nuisance alarms. If a kitchen alarm is desired, it should have an alarm silence feature or be a photoelectric type. • Near fluorescent lights. Electronic “noise” may cause nuisance alarms. • Smoke alarms are not to be used with detector guards unless the combination (alarm and guard) has been evaluated and found suitable for that purpose. 3. INSTALLATION INSTRUCTIONS WIRING REQUIREMENTS • This smoke alarm should be installed on a U.L. listed or recognized junction box. All connections should be made by a qualified electrician and all wiring used shall be in accordance with articles 210 and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdiction in your area. The multiple station interconnect wiring to the alarms must be run in the same raceway or cable as the AC power wiring. In addition, the resistance of the interconnect wiring shall be a maximum of 10 ohms. • The appropriate power source is 120 Volt A.C. Single Phase supplied from a non-switchable circuit which is not protected by a ground fault interrupter. • WARNING: This alarm cannot be operated from power derived from a square wave, modified square wave or modified sine wave inverters. These types of inverters are sometimes used to supply power to the structure in off grid installations, such as solar or wind derived power sources. These power sources produce high peak voltages that will damage the alarm. WIRING INSTRUCTIONS FOR A.C. QUICK CONNECT HARNESS CAUTION! TURN OFF THE MAIN POWER TO THE CIRCUIT BEFORE WIRING THE ALARM. • For alarms that are used as single station, DO NOT CONNECT THE RED WIRE TO ANYTHING. Leave the red wire insulating cap in place to make certain that the red wire cannot contact any metal parts or the electrical box. • When alarms are interconnected, all interconnected units must be powered from a single circuit. • A maximum of 24 Kidde devices may be interconnected in a multiple station arrangement. The interconnect system should not exceed the NFPA interconnect limit of 12 smoke alarms and/or 18 alarms total (smoke, heat, carbon monoxide, etc.). With 18 alarms interconnected, it is still possible to interconnect up to a total of 6 remote signaling devices and/or relay modules. • When mixing models which have battery backup (i12040, i12060, i12080, 1275, 1276, 1285, 1296, PE120, PI2000, KN-COSM-IB, RF-SM-ACDC, HD135F, KN-COB-IC, KN-COP-IC) with models without battery backup, (i1220, 1235, KN-COSM-I, KN-COB-ICB, KN-COP-ICB, 120X, SM120X,CO120X, SL177i) be advised that the models without battery backup will not respond during an AC power failure. • For more information about compatible interconnect units and their functionality in an interconnect system, visit our web site at: • The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet. • Figure 4 illustrates interconnection wiring. Improper connection will result in damage to the alarm, failure to operate, or a shock hazard. • Make certain alarms are wired to a continu...
