ALARM TECHNOLOGY & FEATURES

This is a 3-in-1 combination smoke + fire + carbon monoxide (CO) alarm.  The 10 year sealed 

battery provides continuous protection even in the event of a power outage .
•  There are three basic smoke alarm types: Universal Smoke Sensing Technology

®

, Ionization 

and Photoelectric .

•  Universal Smoke Sensing Technology

®

 is an ionization alarm containing patented Smart 

Alarm Technology .  Alarms containing Universal Smoke Sensing Technology are effective at 

detecting fast flaming fires faster than the maximum allowable alarm limit, and are effective 

at detecting slow smoldering fires.

•  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 alarms containing Universal Smoke Sensing Technology ensures maximum detec-

tion 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 a 3-in-1 Photoelectric 

Smoke + Fire + Carbon Monoxide Smart Alarm.

ALARM LIMITATIONS AND FUNCTIONS

•  IMPORTANT: ALARMS WILL NOT WORK WITHOUT POWER. 

Therefore, installing an 

alarm with a sealed battery or an alarm powered from two different power sources can give 

an extra measure of protection .  A hardwired alarm with backup battery power will provide 

protection in the event of an AC power failure .  Battery operated alarms cannot work if the 

batteries are missing, disconnected or dead . If you are concerned about the limitations of the 

battery or AC power, install both types of alarms .

•  PROPERLY LOCATE THE ALARM TO AVOID NUISANCE ALARMS. 

Using an ionization 

smoke alarm without Universal Smoke Sensing Technology in a smokey area, such as a 

kitchen, or in a high humidity area near a shower, can cause nuisance/false alarms . Also, 

humid areas near a shower can cause nuisance/false alarms .

•  DO NOT DEACTIVATE THE BATTERY TO QUIET A NUISANCE/FALSE ALARM. 

The 

alarm will not provide protection if it is not receiving power .  Properly locate the alarm to 

avoid nuisance/false alarms .

•  SMOKE, CO OR GAS ALARMS MAY NOT ALWAYS WARN ABOUT DANGERS CAUSED 

BY CARELESSNESS.

  Safety hazards such as smoking in bed, violent explosions, escap-

ing gas, improper storage of flammable materials, overloaded electrical circuits, children 

playing with matches, natural causes such as lightning and arson . Prevention and appliance 

maintenance is the best safeguard .

•  INSTALLING ALARMS MAY MAKE YOU ELIGIBLE FOR LOWER INSURANCE RATES, 

BUT ALARMS ARE NOT A SUBSTITUTE FOR INSURANCE. 

 Home-owners 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. Do not obstruct 

airflow around the smoke alarm or place in areas of obstructed airflow. 

•  SMOKE ALARMS MAY NOT BE EFFECTIVE IN VARIOUS AREAS.

 For example: (1) Fires 

where the victim is intimate with fire due to a person’s clothes catching fire while cooking; (2) 

Fires where the smoke is prevented from reaching the alarm due to a closed door or other 

obstruction; (3) Incendiary fires where the fire grows so rapidly that an occupant’s egress is 

blocked even with properly located alarms .
