Types Are Available?
There are two main types: Ionization and

How Many Do I
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.
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.
