What smoke detectors can do:
Smoke detectors are designed to provide early warning of developing
res at a reasonable cost. They monitor the air and can sense smoke and
can provide precious minutes for you and your family to escape before a
re spreads.
Caution: Early warning re detection is best achieved by the installation of
re detector equipment in all rooms and areas of the household as follows:
A smoke detector installed in each separate sleeping area (in the vicinity,
but outside of the bedroom), and heat or smoke detectors in the living
rooms, dining room, bedrooms, kitchens, hallways, attics, furnace rooms,
closets, utility and storage rooms, basements and attached garages.
What smoke detectors cannot do:
Smoke detectors will not work without power. Battery operated detectors
will not work without batteries, with dead batteries, or if the batteries are
not put in properly. AC-powered detectors will not work if their AC power
supply is cut off by an electrical re, and open fuse or circuit breaker, or for
any other reason. If you are concerned about the reliability of either batteries
or your AC power supply for any of the above reasons, you should install
both battery powered and AC powered detectors for maximum safety.

Smoke detectors may not sense res that start where smoke cannot reach
the detectors such as in chimneys, in walls, on roofs, or on the other side
of closed doors. If bedroom doors are usually closed at night, detectors
should be placed in each bedroom as well as in the common hallway
between them.
Smoke detectors also may not sense a re on another level of the residence
or building. For example, a second-oor detector may not sense a rstoor or basement re. Therefore, detectors should be placed on every
level of a residence or building.
The horn in your detector has been tested by ETL to comply with UL 217
(US). However, if the detector is located outside a bedroom, it may not
wake a sound sleeper, especially if the bedroom door is closed or only partly
open. If the detector is located on a different level of the residence than the
bedrooms, it is even less likely to wake up people sleeping in the bedrooms.
In such cases, the National Fire Protection Association recommends that
the detectors be interconnected so that all detectors sound an alarm when
any one of the detectors sense smoke.
All types of smoke detectors have limitations. No type of smoke detector
3
can sense every kind of re every time. In general, detectors may not
always warn you about red caused by carelessness and safety hazards
like smoking in bed, violent explosions, escaping gas, improper storage
of ammable materials, overloaded electrical circuits, children playing
with matches or arson.
Installing smoke detectors may make you eligible for lower insurance
rates, but smoke detectors are not a substitute for insurance. Homeowners
and renters should continue to insure their lives and property.

This smoke detector should be installed in accordance with the National
Fire Protection Association, Standard 72 (National Fire Protection
Association Batterymarch Park, Quincy, MA 002269). This standard
means that for complete coverage, smoke detectors should be installed
in all rooms, halls, storage areas, basements, and attics of a building. The
4
minimum recommendations is one detector on each level of a building
and one in every sleeping area. See how this recommendation applies in
the gures below.
• Put a smoke detector in the hallway outside of every separate bedroom
area. See gure 1. Two detectors are required in homes with two
bedroom areas. See gure 2.
• Put a smoke detector on every level of a multi-level residence. See gure
3.

• put a smoke detector inside bedrooms where a smoker sleeps.
• put a smoke detector inside every bedroom where electrical appliances
(such as portable heaters or humidiers) are operated where someone
sleeps.

• Put a smoke detector inside every bedroom where someone sleeps with
the door closed. Smoke could be blocked by the closed door, or the
alarm may not wake the sleeper if the door is closed.
• Put detectors as close to the center of the ceiling as possible. If this is not
practical, put the detector on the ceiling, but no closer than 4 inches (10
cm) from any wall or corner. See gure 4.
• If wall mounting is permitted by your local and state codes. Put the top
of wall-mounted detectors between 4 and 6 inches (10 and 15 cm) from
the ceiling. see gure 4.
