ALARM LIMITATIONS AND FUNCTIONS 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 and slow smoldering fires.

WHAT YOU SHOULD KNOW ABOUT CO Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn infants with no effect on the mother. The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household: MILD EXPOSURE Slight headache, nausea, vomiting, fatigue (often described as “flu-like” symptoms).
PAGE 4
Natural gas (methane) is typically supplied through a main utility line connected to your home. Early warning is best achieved by the installation of alarms on all floors and areas of the household. WHERE THIS SMOKE, CO AND NATURAL GAS ALARM SHOULD BE INSTALLED • Install an alarm inside each bedroom where the occupant closes the door while sleeping. • An alarm should be installed in any family living unit containing a fuel-burning appliance or fireplace or having an attached garage.
PAGE 5
Tray-Shaped Ceilings: Smoke Alarms or combination alarms shall be installed on the highest portion of the ceiling or on the sloped portion of the ceiling within 12 in. (305 mm) vertically down from the highest point. Mobile Home Installation: For minimum protection, smoke alarms should be installed in compliance with H.U.D. Manufactured Home Construction Safety Standards, Title 24 CFR, Section 3280.208 and Section 3282.
PAGE 6
RECOMMENDED PLACEMENT: NOTE: For any location, make sure no door or other obstruction could prevent the smoke, carbon monoxide or gas from reaching the alarm.

Do NOT locate this alarm: • In garages, kitchens, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas.

• Good ventilation is recommended when household cleaning supplies or similar contaminants are used. • Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient conditions, such as: m Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles). m Negative pressure differential resulting from the use of exhaust fans.

• Simultaneous operation of several fuel-burning appliances competing for limited internal air. • Vent pipe connections vibrating loose from clothes dryers, furnaces or water heaters. • Obstructions in or unconventional vent pipe designs which can amplify the above situations. 2. Extended operation of unvented fuel-burning devices (ranges, ovens, fireplaces). 3. Temperature inversions which can trap exhaust close to the ground. 4. A car idling in an open or closed attached garage or near a home.
