Mobile Homes
Modern mobile homes have been designed to be energy efficient. Install
smoke alarms as recommended in Recommended Locations and
Image 2A.
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 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
CAUTION! Turn off the main power to the circuit before wiring
the alarm.
• This smoke alarm should be installed on a CSA 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 must be run in the
same raceway or cable as the AC power wiring to the alarms.
In addition, the resistance of the interconnect wiring shall be a
maximum of 10 ohms.
• 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, modified square wave or modified sine wave
inverter. These power sources produce high peak voltages that
will damage the alarm.
