Mobile Homes

Mobile homes built in the past five to seven years have been designed to be energy efficient. Install smoke alarms as recommended in Recommended Locations and Image 2A.

In 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 that 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 10 cm (4") and a maximum of 30.5 cm (12") below the ceiling (Image 2A).

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 Image 1A.

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.

Wiring

•This smoke alarm should be installed on a UL listed or recognized junction box. All connections should be made by a qualified electrician and must conform to article 760 of the U.S. National Electrical Code, NFPA 72 and/or any other codes having jurisdiction in your area.

•The appropriate power source is 120 Volt AC Single Phase supplied from a non-switchable circuit which is not protected by a ground fault interrupter.

•The alarm should not be operated on power derived from a square wave or modified square wave inverter. These power sources produce high peak voltages that will damage the alarm.

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.

CAUTION! Kidde alarms and accessories CAN ONLY BE interconnected with other Kidde alarms and accessories. Connection of these devices to another manufacturer’s interconnect system, or connection with equipment from another manufacturer into an existing Kidde system could result in nuisance alarming, failure to alarm, or damage to one or all of the devices in the interconnect system.

•When mixing models which have battery backup with models without battery backup, 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: www.kidde.ca

•The maximum wire run distance between the first and last unit in an interconnected system is 305 m (1000').

•Image 3 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 continuous (non- switched) power line. NOTE: Use standard CSA listed household wire (18 gauge or larger as required by local codes) available at all electrical supply stores and most hardware stores.
