GENERAL
The ASD200 photoelectric (optical) smoke alarm uses a proven concept, the scattered light principle, to "see"
smoke within the alarm chamber.
A regulated pulse of infrared light from a light emitting diode (LED) is introduced into a darkened smoke
alarm chamber approximately every ten seconds to form a precise beam. When smoke enters this chamber,
it interferes with the beam and scatters the light. The amount of light scattered within the chamber is
monitored by a strategically placed photodiode. When a predetermined level of light strikes the photodiode,
the alarm is activated.
The ASD200`s unique smoke chamber design virtually eliminates ambient light interference in a normal
home environment, but still allows easy access for smoke particles from all sides and results in an extremely
sensitive and stable smoke alarm.
WHERE TO LOCATE
As a minimum, smoke alarms should be located between sleeping areas and potential sources of fire such as a
kitchen, heated garage or basement. In single storey homes with one sleeping area, an alarm should be installed
in the hallway outside the bedrooms (see Figure 1). In single storey homes with two separate sleeping areas, a
minimum of two alarms are required, one outside each sleeping area (see Figure 2). In multi-level or split-level
homes, as a minimum, an alarm should be installed outside each sleeping area, in the basement and at every
level of the home (see Figure 3).
• In every room of your home (except the bathroom): Research indicates that substantial increases in warning
time can be obtained with each properly installed, additional alarm.
• In bedrooms: In anticipation of fires originating within these rooms, caused by faulty wiring, lamps, appliances,
smoking or other hazards.
• In hallways: At a distance no greater than 4 meters (13 feet) from the farthest wall and no greater than 8 meters
(26 feet) from the next alarm.
• In the center of a room or hallway: As it is impossible to predict the source of a fire. If it is necessary to place the
alarm on a wall, always locate the top of the smoke alarm 10-15 cm (4-6 inches) from the ceiling.
• As needed: To compensate for closed doors and other obstacles that may interfere with the path of smoke to an
alarm. They may also prevent occupants on one side of a closed door from hearing an alarm on the other side
of the door.
• Model ASD200 - Hardwire model can be located in any area of the home, except the bathroom.

WHERE TO LOCATE SMOKE ALARMS IN MOBILE HOMES
NOTE: Power supply must be 12/28 Volts DC for model ASD200.
In mobile homes built after 1978, locate the smoke alarm as described above. Older mobile homes may have little
or no insulation compared to the ones built post-1978. These uninsulated exteriors can disrupt airflow around the
smoke alarm in hotter or colder weather. Locate the alarm only on interior walls 10 to 15 cm (4" to 6") from ceiling
1. if you own an older mobile home, or 2. if you notice the exterior walls and/or ceiling are noticeably cold or warm
or 3. if you are uncertain about the quality of insulation.
Regardless of the age of the mobile home, locate alarms throughout to ensure maximum protection. Follow the
location instructions in this manual.
NFPA RECOMMENDATIONS
For your information, the National Fire Protection Association's Standard 72, reads as follows:
2-2.1.1.1 Smoke alarms shall be installed outside of each separate sleeping area in the immediate vicinity of the
bedrooms and on each additional storey 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.
A-2.5.2.1 Smote Detection - Are More Smoke Alarms Desirable? The required number of smoke alarms
might not provide reliable early warning protection for those areas separated by a door from the
areas protected by the required smoke alarms. For this reason, it is recommended that the
householder consider the use of additional smoke alarms for those areas for increased protection.
The additional areas include the basement, bedrooms, dining room, furnace room, utility room,
and hallways not protected by the required smoke alarms. The installation of smoke alarms in
kitchens, attics, (finished or unfinished), or garages is not normally recommended, as these
locations occasionally experience conditions that can result in improper operation.
LOCATIONS TO AVOID
Avoid locations where smoke may not reach the alarm in time to provide early warning, or where the alarm
may not be effective.
DO NOT PLACE SMOKE ALARMS:
• In turbulent air from fans, doors, windows, etc. The rapid air movement may prevent combustion particles
from entering the alarm.
• In dead air spaces such as at the peak of an "A" frame ceiling. "Dead air" at the top may prevent smoke
from reaching the alarm in time to provide early warning. In rooms with simple sloped, peaked or gabled
ceilings, install smoke alarms on the ceiling
90 cm (3 feet) from the highest point of the ceiling.
Note: For complex ceiling structures, consult a safety expert for the number of alarms required and the
best locations.
• In very hot or cold areas where the temperature exceeds 38 0 C (100 0 F) or falls below 5
• Less than 15 cm (6 inches) from the wall when mounted on the ceiling.
Nuisance alarms could result when smoke alarms are located where interference may occur with the sensing
chamber. To avoid nuisance alarms, DO NOT place smoke alarms:
• In high humidity areas such as bathrooms and attics. Place smoke alarms at least 3 meters (10 feet) away
from bathrooms.
• In insect-infested areas.
• In poorly ventilated kitchens or garages.
• In very dusty and dirty areas.
• Near fluorescent lights. Place smoke alarms at least 1.5 meters (5 feet) from fluorescent lights.
This smoke alarm is suitable for residential use. It is not to be connected to a

commercial or industrial fire alarm panel.
INSTALLATION & TESTING
IMPORTANT: This alarm cannot be used with detector guards.
The ASD200 can be set with either momentary or standard contacts. The unit comes wih a relay default
setting providing momentary contacts. Cut the 2 inch RED wire link (placed beside the relay and relay
therminal block) to change relay to standard mode.
WARNING: Wiring should only be installed by a licensed electrician in accordance with the Canadian Electrical
Code and local codes.
WARNING: The circuit used to power the smoke alarm must be a 24 hour voltage circuit that cannot be turned off
by a switch or a ground fault interrupter. It is highly recommended that smoke alarms be wired on a separate
circuit (one with no other lights or appliances) to ensure maximum reliability of DC power supply. For installation of
smoke alarms in Dwelling Units, it is important to follow the Canadian Electrical Code and local codes.
