Limitations Of Smoke Alarms - Kidde i9030 User Manual

6. Maintenance
lamp holder assembly. Slide the old lamp out of the lamp holder and
replace it with a new lamp. Replace with the correct lamp type: Vanco
#FTB 6 which is available at most radio/tv repair stores.
Reinstall the lamp holder. It will snap easily into the base. Put working
batteries back in the alarm and remount the alarm on its mounting
bracket.
CAUTION: Use only the lamp specified. Use of a different lamp
may have a detrimental effect on the smoke alarm or the safety
light operation.
NOTE: The safety light is not intended to satisfy the requirements
for approved illumination under various local codes. Very thick
and/or dense smoke may obscure the light.

7. Limitations of Smoke Alarms

WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
• NFPA 72 states: Fire-warning equipment for residential occupancies
are capable of protecting about half of the occupants in potentially
fatal fires. Victims are often intimate with the fire, too old or too
young, or physically or mentally impaired such that they cannot
escape even when warned early enough that escape should be possi-
ble. For these people, other strategies such as protection-in-place or
assisted escape or rescue would be necessary.
• 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.
• A battery powered alarm must have a battery of the specified type, in
good condition and installed properly.
• AC powered alarms (without battery backup) will not operate if the
AC power has been cut off, such as by an electrical fire or an open
fuse.
• Smoke alarms must be tested regularly to make sure the batteries and
the alarm circuits are in good operating condition.
• Smoke alarms cannot provide an alarm if smoke does not reach the
alarm. Therefore, smoke alarms may not sense fires starting in chim-
neys, walls, on roofs, on the other side of a closed door or on a differ-
ent floor.
