Installation, Understanding Your CO Alarm

UNDERSTANDING YOUR CO ALARM

WELCOME CHIRP

Horn chirps and light blinks once when batteries are first connected.

ALARM RECEIVING BATTERY POWER

Light flashes every minute. Horn is silent.

LOW BATTERY WARNING

The light continues to flash (RED) and the horn also “chirps” once every minute. This warning should last for up to 30 days, but you should replace the batteries as soon as possible.

DURING TESTING

Light flashes Red in sync with the horn pattern (4 beeps, pause, 4 beeps), simulating a CO Alarm condition.

CO ALARM

Sensor has detected enough CO to trigger an alarm. Light flashes rapidly and horn sounds loudly (repeating 4 beeps, pause). See “If Your CO Alarm Sounds” for details. During an alarm, move everyone to a source of fresh air. DO NOT move the CO Alarm!

CO ALARM REQUIRES SERVICE (MALFUNCTION SIGNAL)

The light flashes (RED) and the horn sounds 3 quick “chirps” every minute. CO Alarm needs to be replaced.

INSTALLATION

WHERE TO INSTALL CO ALARMS

The National Fire Protection Association (NFPA) recommends that a CO Alarm should be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms. For added protection, install additional CO Alarms in each separate bedroom, and on every level of your home.

If your bedroom hallway is longer than 40 feet (12 meters), install a CO Alarm at BOTH ends of the hallway.

BEDROOM	BEDROOM	BEDROOM
	KITCHEN	GARAGE
LIVING ROOM	HALL

BASEMENT

REQUIRED TO MEET NFPA RECOMMENDATIONS SUGGESTED AREAS FOR INSTALLING ADDITIONAL CO ALARMS

In a Single-level Home:

•Install at least one CO Alarm near or within each separate sleeping area.

•For added protection, install an additional CO Alarm at least 20 feet (6 meters) away from the furnace or fuel burning heat source.

In a Multi-level Home:

•Install at least one CO Alarm near or within each separate sleeping area.

•For added protection, install at least one CO Alarm on each level of the home.

•For added protection, install an additional CO Alarm at least 20 feet (6 meters) away from the furnace or fuel burning heat source.

In Mobile Homes:

•Install CO Alarms on inside walls ONLY. Uninsulated outside walls and roofs of mobile homes often transfer heat and cold from outdoors. The Alarm should be located at least 152 mm (6 inches) from all exterior walls and at least 305 mm (12 inches) from supply or return vents.

WHERE CO ALARMS SHOULD NOT BE INSTALLED

DO NOT LOCATE THIS CO ALARM:

•In garages, kitchens, furnace rooms, or in any extremely dusty, dirty or greasy areas.

•Within 5 feet (1.5 meters) of any cooking appliance.

•In extremely humid areas. This alarm should be at least 10 feet (3 meters) from a bath or shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other source of high humidity.

•In areas where temperature is colder than 40˚ F (4˚ C) or hotter than 100˚ F (38˚ C). These areas include unconditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.

•In turbulent air, like near ceiling fans, heat vents, air conditioners, fresh air returns, or open windows. Blowing air may prevent CO from reaching the sensors.

•Outside the Mobile Home.

•In direct sunlight.

•This CO Alarm is designed for use inside a single-family home or apartment. It is not meant to be used in common lobbies, hallways, or basements of multi-family buildings unless working CO Alarms are also installed in each family living unit. CO Alarms in common areas may not be heard from inside individual family living units.

•This CO Alarm alone is not a suitable substitute for complete detection systems in places which house many people, like hotels or dormitories, unless a CO Alarm is also placed in each unit.

•DO NOT use this CO Alarm in warehouses, industrial or commercial buildings, special-purpose non-residential buildings, or airplanes. This CO Alarm is specifically designed for residential use, and may not provide adequate protection in non-residential applications.

CO400 specifications
