Install Smoke Alarms on sloped, peaked or cathedral
ceilings at or within 3 ft (0.9m) of the highest point
(measured horizontally). NFPA 72 states: “Smoke alarms in
rooms with ceiling slopes greater than 1 ft in 8 ft (0.3m in
2.4m) horizontally shall be located on the high side of the
room.” NFPA 72 states: “A row of alarms shall be spaced
and located within 3 ft (0.9m) of the peak of the ceiling
measured horizontally” (See Diagram 6).

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
diagram 5 and 6).
•
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" (10cm) and a maximum of 12" (30.5cm)
below the ceiling (see Diagram 5 ).
•
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
ONLY
.
For minimum protection, install at least one alarm close to
the bedrooms. For additional protection, see SINGLE
FLOOR PLAN and MULTIPLE FLOOR PLAN in
Diagram 7.

WARNING
: TEST YOUR SMOKE ALARM OPERATION
AFTER MOBILE HOME HAS BEEN IN STORAGE, BEFORE
EACH TRIP AND AT LEAST ONCE A WEEK DURING USE.
Wiring Instructions:
The appropriate power source is 120 volt AC single phase.
When installing or removing the smoke alarm
，
you must
turned off the AC power distribution panel to ensure
safety.
Connecting wires shall be a minimum of 18 AWG and
shall be installed in accordance with the National
Electrical Code, NEC, NFPA 70 Article 780.
The smoke alarm AC primary (main) power shall be
supplied either from a dedicated branch circuit or the
unswitched portion of a branch circuit also used for power
and lighting. Should use the terminal to connect the AC
QUICK CONNECTOR and AC main power supply. The
terminal should allow the connection of conductors
having nominal cross-sectional areas of between 0.4mm
2
and 1.5 mm
2
(refer to Diagram 10).
When a
l
arms are interconnected, all interconnected units
must be powered from a single circuit.
A maximum of 12 Siterwell devices may be interconnected
in a multiple station arrangement, do not exceed this
number as it may cause an unsafe condition.
Diagram 8 illustrates proper interconnection wiring,
improper connection may result in damage to the alarm,
failure to operate, or a shock hazard.
