SMOKE & FIRE ALARM
SMOKE ALARM LIMITATIONS AND FUNCTIONS
There are three basic smoke alarm types: IoPhic , Ionization and Photoelectric.
IoPhic is an ionization alarm containing a patent-pending Universal Smoke Sensing Technology. IoPhic
alarms are very effective at detecting fast flaming fires and also respond very quickly to slow smoldering
fires - up to 87% faster than the maximum allowable alarm limit (UL217 Smoldering Smoke Test on 5/26/2010,
Underwriters Laboratories Project #09CA38078).
Ionization smoke alarms are typically more effective at detecting fast flaming fires - fires which consume combustible
materials rapidly and spread quickly. Sources of these fires may include paper burning in a wastebasket, or kitchen
grease fires.
Photoelectric smoke alarms, on the other hand, are typically more effective at detecting slow smoldering fires - fires
which burn for hours before bursting into flame. Sources of these fires may include cigarettes burning in couches
or bedding.
Installing IoPhic smoke alarms ensures maximum detection of both types of fires from a single alarm, while
eliminating the need for a combination of ionization and photoelectric smoke alarms.
The enclosed alarm is an Ionization smoke alarm.

SMOKE ALARMS WILL NOT WORK DURING A LOSS OF POWER. SINCE A SMOKE ALARM WILL NOT WORK
WITHOUT POWER, having an alarm(s) that works from two completely different power sources, such as an AC direct
wire with battery backup smoke alarm, can give you an extra measure of protection in case of an AC power failure or
a dead battery. Battery operated alarms cannot work if the batteries are missing, disconnected or dead, if the wrong
type of batteries are used or if the batteries are not installed correctly. AC (only) powered alarms cannot work if the
AC power is cut off for any reason. If you are concerned about the limitations of the battery or AC power, install both
types of alarms.
USING AN IONIZATION SMOKE ALARM IN A SMOKY AREA, SUCH AS A KITCHEN, OR IN A HIGH HUMIDITY
AREA NEAR A SHOWER, CAN CAUSE NUISANCE FALSE ALARMS. IT IS PREFERABLE TO USE
PHOTOELECTRIC ALARMS IN THESE AREAS. DO NOT TURN OFF THE AC POWER TO QUIET THE
ALARM. A SMOKE ALARM WILL NOT HELP PROTECT YOU IF IT IS NOT POWERED. Properly locate your
alarm to avoid nuisance alarms.
A SMOKE ALARM MAY NOT ALWAYS WARN YOU ABOUT FIRES CAUSED BY CARELESSNESS AND SAFETY
HAZARDS LIKE SMOKING IN BED, VIOLENT EXPLOSIONS, ESCAPING GAS, IMPROPER STORAGE OF
FLAMMABLE MATERIALS, OVERLOADED ELECTRICAL CIRCUITS, CHILDREN PLAYING WITH MATCHES,
NATURAL CAUSES SUCH AS LIGHTNING, OR ARSON. FIRE PREVENTION IS YOUR BEST SAFEGUARD.
INSTALLING SMOKE ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE RATES, BUT SMOKE
ALARMS ARE NOT A SUBSTITUTE FOR INSURANCE. Homeowners and renters alike should continue to insure
their lives and properties.
SMOKE ALARMS CANNOT DETECT FIRES IF THE SMOKE DOES NOT REACH THEM. Smoke from fires
may not reach the sensing chamber and set off the alarm. One alarm should be installed inside each bedroom or
sleeping area. Do not obstruct airflow around the smoke alarm or place in areas of obstructed airflow.
BE AWARE OF VARIOUS SITUATIONS AGAINST WHICH THE SMOKE ALARM MAY NOT BE EFFECTIVE. For
example: (1) Fires where the victim is intimate with a flaming initiated fire; for example, when a person's clothes catch
fire while cooking; (2) Fires where the smoke is prevented from reaching the alarm due to a closed door or other
obstruction or (3) Incendiary fires where the fire grows so rapidly that an occupant's egress is blocked even with
properly located alarms.
SMOKE ALARMS MAY NOT DETECT FIRE ON ANOTHER FLOOR OR AREA OF THE HOME. Recommended
minimum protection is at least one smoke alarm in every sleeping area and every bedroom on every level of your home.
Interconnected smoke alarms may provide earlier warning than stand-alone smoke alarms since all smoke alarms
alarm when one detects smoke.
SMOKE ALARMS MAY NOT BE HEARD. The alarm horn in this alarm meets or exceeds current standards, but
it may not be heard if: (1) the smoke alarm is located outside a closed or partially closed door; (2) residents recently
consumed alcohol or drugs; (3) the alarm is drowned out by noise from stereos, TV's, air conditioners or other
appliances; (4) residents are hearing impaired or (5) if residents are sleeping.
CURRENT STUDIES HAVE SHOWN SMOKE ALARMS MAY NOT AWAKEN ALL SLEEPING INDIVIDUALS
AND THAT IT IS THE RESPONSIBILITY OF INDIVIDUALS IN THE HOUSEHOLD WHO ARE CAPABLE OF
ASSISTING OTHERS TO PROVIDE ASSISTANCE TO THOSE WHO MAY NOT BE AWAKENED BY THE
ALARM SOUND OR TO THOSE WHO MAY BE INCAPABLE OF SAFELY EVACUATING THE AREA
UNASSISTED.
SMOKE ALARMS ARE NOT FOOLPROOF. You must test the smoke alarm weekly to ensure your continued
protection. Smoke alarms cannot prevent or extinguish fires.
SMOKE ALARMS HAVE A LIMITED LIFE. The smoke alarm should be replaced immediately if it is not operating
properly. You should always replace a smoke alarm after 10 years.
SMOKE ALARMS ARE NOT TO BE USED WITH DETECTOR GUARDS UNLESS THE COMBINATION HAS
BEEN EVALUATED AND FOUND SUITABLE FOR THAT PURPOSE.
