Technical Bulletin
This smoke detector is a member of SMC
Networks’ family of reliable, high-quality
products using the latest technology available.
Review the information in this section to ensure
you get the most out of the smoke detector. The
information in this guide is in accordance with
NFPA 72 and/or CAN/ULC-S524, depending on
country of installation.
Pre-installation Considerations
Install the smoke detector in accordance with
the National Fire Protection Association’s (NFPA)
Standard 72, Chapters 2 and 8. Depending on
the application, you may need to reference
other chapters of NFPA 72 or NFPA 101.
Choosing an Installation Location
When choosing an installation location,
consider:
¾
Use of structure and type of construction
¾
Contents you want to protect and their
burning characteristics
¾
Human occupancy
¾
Total area to be monitored
¾
Ceiling height and surface condition
¾
Air movement and vent locations
¾
Obstructions
¾
Deflections
After considering these factors, choose a
location:
¾
Where the temperature range is between
40° and 100° F (4.4° and 37.8° C).
¾
Where the humidity is between 0 and 90%
noncondensing.
¾
Away from ventilation sources that can
prevent smoke from reaching the smoke
detector.
¾
That is at least 5 feet (1.5 m) from
bathrooms.
When placing the smoke detector on a ceiling,
mount it in the center of the room or hallway,
at least 4 inches (10cm) away from any walls or
partitions.
When mounting the smoke detector on a wall,
place it so the top is 4 to 12 inches (10 to 31cm)
below the ceiling.
In rooms with sloped, peaked, or gabled
ceilings, place smoke detectors 3 feet (.9 m)
down or away from the highest point of the
ceiling.
If mounting to suspended ceiling tile, secure the
tile with the appropriate fastener to prevent tile
removal.
Note:
The smoke detector does not provide
warnings for fires resulting from explosions,
smoking in bed, or other furniture; ignition of
flammable liquids, vapors and gasses; and
children playing with matches or lighters.
Locations to Avoid
¾
Areas where normal ambient temperature
exceeds 100° F (37.8° C).
¾
Damp or humid areas, or near bathrooms
with showers.
¾
On the ceiling in rooms next to kitchens,
where there is no transom between the
kitchen and such rooms.
¾
Within 10 feet (3 m) of fluorescent light
fixtures.
¾
Dirty, dusty, insect infested areas.
