What Does a Smoke Alarm
Do? The purpose of a residential smoke alarm is to sense the presence
of smoke in the home, to sound an alarm and alert the occupants, giving them time
to escape. Back
What
Types Are Available? There are two main types: Ionization and
Photoelectric Ionization smoke
alarms contain a small chamber that produces electrically charged air molecules
called ions. When smoke enters the chamber, it causes a change in the flow of
ions, triggering the alarm. Photoelectric
smoke alarms contain a light source whose beam is deflected by smoke into a photo-cell,
thereby causing an alarm to sound. Both
types provide effective protection. Smoke alarms can either be wired into the
household electrical system or be battery operated. Other
Options Available Include: - Interconnectable
models which sound alarms in all connected units.
- Models
incorporating an emergency light
- Models
for the hearing-impaired that flash a light in addition to sounding an alarm.

How Many Do I
Need? A smoke alarm outside each sleeping area and on each level
of the home provides a reasonable degree of protection from the threat of fire.
In a single-level home, one alarm may be sufficient if all the bedrooms connect
to a common passageway from the living areas. Extra alarms are warranted in homes
with separated sleeping areas. If occupants sleep with bedroom doors closed, install
a smoke alarm in each bedroom, particularly if heaters or electrical appliances
are used in these rooms. In all cases, be sure everyone sleeping in your home
can hear all smoke alarms. Smoke
alarms are not recommended for kitchens, bathrooms or garages, where cooking fumes,
steam or exhaust could set off false alarms. The smoke alarms should be installed
between the living and sleeping areas in all dwelling units. Back
How Do I Install
My Smoke Alarm? If you can
handle a screw-driver and operate a drill, you can install a battery-operated
smoke alarm. They are simply fastened with two small screws. Household
current smoke alarms should be installed by a licensed electrician. Because
smoke rises, mount alarms high on a wall or on the ceiling. For effective operation
smoke alarms should be located away from corners. Don t install a smoke alarm
too near a window, door, or forced-air register where drafts could interfere with
the unit s operation. On a normal flat ceiling install the smoke alarm a minimum
of 6 inches from the nearest wall. On
a wall, locate the top of the alarm between 6 inches and 12 inches from the ceiling.
In rooms with high pitched ceilings, mount the alarm at or near the ceiling high
point. Back
