Research has shown that all hostile fires in homes generate smoke
to a greater or lesser extent. Experiments with typical fires in homes
indicate that detectable quantities of smoke precede detectable
levels of heat in most cases. For these reasons, smoke alarms
should be installed outside of each sleeping area and on each
storey of the home.
The following information is for general guidance only and it is
recommended that local fire codes and regulations be consulted
when locating and installing smoke alarms.
It is recommended that additional smoke alarms beyond those
required for minimum protection be installed. Additional areas that
should be protected include: the basement; bedrooms, especially
where smokers sleep; dining rooms; furnace and utility rooms, and
any hallways not protected by the required units.
A smoke alarm should be located between the sleeping area and
the rest of the home as in Figure 1. In homes with more than one
sleeping area, a smoke alarm should be located outside of each
sleeping area, as in Figure 2. A smoke alarm should be located on
each storey of the home, as in Figure 3.
Smoke from a fire generally rises to the ceiling, spreads out across
the ceiling surface, and begins to bank down away from the ceiling.
Because of this airflow behaviour, the smoke may not be able to
enter the corner where the ceiling and wall meet. In most cases, this
"dead" air space measures about 4 in. (10 cm) along the ceiling
from the corner and about 4 in. (10 cm) down the wall as shown in
Figure 4. Units should not be placed in the "dead" air space.
Locations to avoid:
• Do not locate smoke alarms at the top of peaked or gabled
ceilings; the "dead" air in these locations may prevent the unit
from detecting smoke.
• Avoid areas with turbulent airflow, such as near fans, doors or
windows. Rapid airflow around the unit may prevent smoke from
entering the unit.
• Do not locate smoke alarms in high humidity areas, such as in
bathrooms or attics. Also avoid areas where the temperature
rises above 38°C (100°F) or falls below 5°C (41°F).
• Do not locate smoke alarms in poorly ventilated garages or
kitchens; car exhaust or cooking smoke could cause false alarms.
Smoke detectors should always be installed in accordance with NFPA 72,
the National Fire Alarm Code. Smoke detectors should always be located
in accordance with Paragraph 2.1.1.1 of NFPA 72, Chapter 2.:
"2-2.1.1.1 Smoke detectors 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 detector
also shall be installed in each sleeping room."
Testing Your Smoke Alarm
Never use burning or smouldering materials to test a smoke
alarm. Follow the test procedure described here or contact
your Smoke Alarm Dealer or Installer for testing instructions.
It is recommended that your entire alarm system be tested at
least once per week to verify the operation of all system functions.
Smoke Alarm Unit Test
To test the smoke alarm, press and hold the Test Button on the front
of the unit. When the button is pressed, the unit's alarm should
sound. When the button is released, the alarm should be silenced.
If this does not occur, check that the batteries are the correct type,
in good condition and are installed correctly (see the Battery
Installation section). If the smoke alarm still does not function
properly, call your smoke alarm Installer or Dealer for service.
System Test
To prepare your alarm system for a complete test, refer to the testing
instructions section of your system's manual. Observe carefully all
instructions regarding notification of the monitoring station in
order to avoid an unnecessary emergency response. When the
system is ready to be tested, hold the test magnet against the smoke
alarm case as shown below.
If you have a Marquis (WLS900) system, and it is not in
walk test mode when the system test is performed, the
System Controller will transmit a fire alarm to the
monitoring station.
After activating the smoke alarm's system test, an alarm should
sound and the indicator light should flash every 0.67 seconds.
When the magnet is removed, the alarm should be silenced. See
your system manual for further instructions regarding
completion of the alarm system test.
