Smoke-alarms shall be installed outside of each separate sleeping area in the
immediate vicinity of the bedrooms and on each additional story of the family
living unit, including basements and excluding crawl spaces and unfinished
attics. In new construction, a smoke-alarm also shall be installed in each sleeping
room."
For better protection, we also require the installation of a smoke-alarm inside
every bedroom in existing construction.
Install a minimum of two smoke-alarms in any household, no matter how
small it is.
Put a smoke-alarm in the hallway outside of every separate bedroom area.
(See Figure 1.) A minimum of two smoke-alarms are required in homes
with two bedroom areas. (See Figure 2.)
Put a smoke-alarm on every level of a multi-level residence.(See Figure 3.)
Install basement smoke-alarms on the ceiling at the bottom of the
basement stairwell. (See Figure 3.)

Install smoke-alarms on the ceiling as close to the center of the room as
possible. If this is not practical, install it on the ceiling no closer than 4
inches (10 cm) from any wall or corner. (See Figure 4.)
If wall-mounting is permitted by local and state codes, and ceiling
mounting is not practical, install smoke-alarms on an inside wall between
4 and 6 inches (10 and 15 cm) from the ceiling. (See Figure 4.)

ACCEPTABLE LOCATION
Put smoke-alarms at both ends of a bedroom hallway if the hallway is
more than 30 feet (9 meters) long. In addition, large rooms will require
more than a single smoke-alarm if the room is over 900 square feet.
Rooms or areas that do not have smooth ceilings, or which have short,
transom-type walls coming down from the ceiling require additional
smoke-alarms.
Install second-floor smoke-alarms on the ceiling at the top of the first-to-
second floor stairwell. Be sure no door or other obstruction blocks the path
of smoke to the smoke-alarm.
In rooms with sloped, peaked, or gabled ceilings, install smoke-alarms 3 feet (0.9
meter) measured down on the slant from the highest point of the ceiling. See
Figure 5

or peaked ceilings:

Where Smoke-alarms Should NOT Be Installed
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
smoke-alarms at least 20 feet (6 meters)away from kitchens and other
areas where combustion particles are normally present.
On the ceiling in rooms next to kitchens where there is no transom
between the kitchen and these rooms. Instead, install the smoke-alarm
inside wall, furthest from the kitchen (See Figure 6). Be sure not to
install smoke-alarms within 4" of the ceiling or any corner or more than
6" from the ceiling.

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 and condense into droplets that cause a nuisance alarm. Install smoke-
alarms at least 5 feet (1.5 meters) away from bath- rooms.
In very cold or very hot rooms or areas. Operating temperature of the
smoke-alarm is -10°C to 55°C.
In dusty, dirty, or insect-infested areas. Dust and dirt can build up on the
smoke-alarm's sensing chamber and make it overly sensitive, or can block
openings to the sensing chamber and keep the smoke-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 away from smoke-alarms, making the units less effective.
In dead air spaces at the top of a peaked ceiling or wall/ceiling inter sect.
Dead air may prevent smoke from reaching a smoke-alarm.
Near fluorescent light fixtures. Install smoke-alarms at least 10 feet (3
meters) away from such light fixtures.
Installation Requirements
Warning: Electrical Shock Hazard. Turn off power at the main fuse box or circuit
breaker to the area of smoke-alarm installation before beginning installation
procedures.
Mount smoke-alarm to a 4-inch octagonal junction box only. Mount the
12/24 Volt D.C. power supply to a 4" square junction box 2-1/8" deep
only. (If necessary, add an extension ring if the selected box does not have
adequate volume.) The power supply may be mounted remotely from the
smoke-alarm.
All wiring must be performed by a licensed electrician.
Use only the specified wire gauge.
The smoke-alarm includes a tamper-resist feature that, when activated,
requires a tool for smoke-alarm removal. The following smoke-alarm
installation instructions include how to activate this feature.

For 24VDC supply voltage, the maximum power bus length is 4 times as long as 12VDC supply voltage.
Maximum interconnect bus length: 2000 meters, 0.75mm
All wiring must conform to local electrical codes.
Installation Instructions
1.
Turn off power at main service panel.
2.
Using wire connectors, connect power supply output wires to the bus line
wires supplying power to the remote smoke-alarms. (See Figure 7.) Use
color-coded bus wires.
3.
Mount power supply to junction box and cover junction box with a 4"
square box cover, using box mounting screws.
4.
Install a junction box where you plan to install the smoke-alarm. (See type
and size for junction box above.)
Install bus line wires from power supply output to junction box. Use 0.75
5.
to1.5mm wire only. See Figure 7 to determine maximum power bus length for
wire size and number of interconnected smoke-alarms.
6.
Connect color-coded DC power bus wires to power input screw terminals,
located on smoke-alarm back. If smoke-alarms will be interconnected or the
relay used, see following sections for specific installation instructions.
7.
Remove smoke-alarm from mounting bracket by turning the smoke-alarm
counter-clockwise and pulling the smoke-alarm away from the bracket.
8.
Remove small tab on mounting bracket to activate tamper-resist feature, if
desired. (To release a smoke-alarm with this feature, push up on locking tab
with screwdriver while turning smoke-alarm counterclockwise.)
9.
Install mounting bracket to junction box.
10. Connect power wires to the smoke-alarm(s) as shown in Figure 8. Be sure
to tighten each terminal screw to secure wire in place. Tug wire to be sure it
is connected properly.
11. Battery installation instruction
Please open the cover of the battery box on the base with a screwdriver ;
Then take the battery button out of the box carefully;
Fasten the battery into the button.
Insert the battery into the box, lock the battery cover with a screwdriver.
NOTE:
Only the allowed battery model can be used.
Recommended periodic battery replacement interval: 18 months.

The battery box cover will be held up by the spring slice and can not
be closed if the battery is not installed.
Replacement 9VDC batteries can be purchased from the following
retail outlets throughout Australia & New Zealand:
Bunnings, Mitre 10, Tandy and Dick Smith.
12. Attach the smoke-alarm to mounting bracket by aligning arrows on side of
mounting bracket 1-inch to the right of the nib on the smoke-alarm. Rotate
until the arrow and nib line up. (See Figure 8).
13. After installing all smoke-alarms, turn on power at the main service panel.
14. Check for the green LED to flash once about 40 seconds. This means the
smoke-alarm is receiving power. Check all smoke-alarms.
Note: If the LED does not flash, power is not getting to the smoke-alarm.
Check wiring. If LED still does not flash, return the smoke-alarm to the
manufacturer for repair.
Test each smoke-alarm in the system. (See "Testing" below for more
detailed instructions.)
