Smoke Alarm Procedure
NEVER IGNORE THE SOUND OF THE ALARM!
Smoke alarms are designed to minimize false alarms. Cigarette
smoke will not normally set off the alarm, unless the smoke is
blown directly into the alarm. Combustion particles from cooking
may set off the alarm if it is located too close to the cooking area.
Large quantities of combustion particles are generated from spills or
when broiling. Using the fan on a range hood which vents to the
outside (non-recirculating type) will also help remove these
combustion particles from the kitchen.
If the alarm sounds, check for fires first. If a fire is discovered,
follow these steps. Become thoroughly familiar with these steps
and review with all family members:
• Alert small children in the home.
• Leave immediately by your escape plan. Every second counts, so
don’t waste time getting dressed or picking up valuables.
• In leaving, don’t open any inside door without first feeling its
surface. If hot, or if you see smoke seeping through cracks, don’t
open that door! Instead, use your alternate exit. If the inside of
the door is cool, place your shoulder against it, open it slightly
and be ready to slam it shut if heat and smoke rush in.
• If the air is smoky, stay close to the floor. Breathe shallowly
through a cloth, wet if possible.
• Once outside, go to your selected meeting place and make sure
everyone is there.
• Call the fire department from your neighbor’s home – not from yours!
• Don’t return to your home until the fire officials say that it is all
right to do so.

well as specified brands and models of interconnect compatible alarms.
Connection of Kidde products to a non-specified manufacturer’s
interconnect system, or connection with non-specified equipment from
another manufacturer into an existing Kidde system could result in
nuisance alarming, failure to alarm, or damage to one or all of the
devices in the interconnect system. Refer to the User’s Guide supplied
with each Kidde product for interconnect compatible models, brands,
and devices. Refer to the wiring instructions in section 3 for NFPA
initiating device limits.

This alarm detects products of combustion using the ionization
technique. It contains 0.9 microcurie of Americium 241, a radioactive
material (see section 9). Distributed under U.S. NRC License No.
32-23858-01E. Manufactured in compliance with U.S. NRC safety
criteria in 10 CFR 32.27. The purchaser is exempt from any regulatory
requirements. Do not try to repair the smoke alarm yourself. Refer to the
instructions in section 11 for service.
Smoke alarms are devices that can provide early warning of possible fires
at a reasonable cost; however, alarms have sensing limitations. Ionization
sensing alarms may detect invisible fire particles (associated with fast
flaming fires) sooner than photoelectric alarms. Photoelectric sensing
alarms may detect visible fire particles (associated with slow smoldering
fires) sooner than ionization alarms. Home fires develop in different ways
and are often unpredictable. For maximum protection, Kidde
recommends that both Ionization and Photoelectric alarms be installed.
LOSS OF POWER (AC AND BATTERY BACKUP) TO THE ALARM
WILL RENDER THIS ALARM INOPERATIVE.
ELECTRICAL RATING: 120 VAC, 60HZ, 30mA maximum per alarm
(maximum 30mA for originating unit with 24 devices interconnected. The
interconnect system should not exceed the NFPA interconnect limit of
12 smoke alarms and/or 18 alarms total (smoke, heat, carbon monoxide,
or similar alarms).
Product Specifications
• Locate the first alarm in the immediate area of the bedrooms. Try to
monitor the exit path as the bedrooms are usually farthest from the
exit. If more than one sleeping area exists, locate additional alarms in
each sleeping area (See Image 1A and 1B).
• Locate additional alarms to monitor any stairway as stairways act like
chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances are
operated (i.e. portable heaters or humidifiers).
• Locate an alarm in every room where someone sleeps with the door
closed. The closed door may prevent an alarm not located in that
room from waking the sleeper.
• Smoke, heat, and combustion products rise to the ceiling and spread
horizontally. Mounting the smoke alarm on the ceiling in the center of
the room places it closest to all points in the room. Ceiling mounting
is preferred in ordinary residential construction.
• When mounting an alarm on the ceiling, locate it at a minimum of 10
cm (4”) from the side wall (see Image 2A).
• When mounting the alarm on the wall, use an inside wall with the top
edge of the alarm at a minimum of 10 cm (4”) and a maximum of
30.5 cm (12”) below the ceiling (see Image 2A).
• Put smoke alarms at both ends of a bedroom hallway or large room if
the hallway or room is more than 9.1 m (30 ft) long.
