Kidde KN-OOB-B manual Features and Operation, Red Alarm Indicator Light

Installation Instructions (cont.)

•Insure that all vents of the unit are unobstructed.

•Do not install in dead air spaces such as peaks of vaulted ceilings, or gabled roofs.

•Do not install in turbulent air from ceiling fans. Do not place near fresh air vents or close to doors and windows that open to the outside.

•Keep the CO alarm away from excessively dusty, dirty, or greasy areas such as kitchens, garages and furnace rooms. Dust, grease and household chemicals can affect the sensor.

•Keep out of damp and humid areas such as the bathroom. Avoid spraying aerosols near the CO alarm.

•Do not install in areas where the temperature is below 40˚ Fahrenheit (4.4˚ Celsius) or hotter than 100˚ Fahrenheit (37.8˚ Celsius).

•Do not place behind curtains or furniture. CO must be able to reach the sensor for the unit to accurately detect carbon monoxide.

The following conditions can result in transient CO situations:

Excessive spillage or reverse venting of fuel-burning appliances caused by:

•outdoor ambient conditions, such as wind direction and/or velocity, including high gusts of wind, and insufficient draft in the vent pipes;

•negative pressure differential resulting from the use of exhaust fans;

•simultaneous operation of several fuel-burning appliances competing for limited internal air;

•loose vent pipe connections from fuel-fired appliances;

•obstructions, or unconventional vent pipe designs that can amplify the above situations;

•poorly designed or maintained chimneys and/or vents;

Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.);

Temperature inversions that can trap exhaust gasses near the ground; and a

Car idling in an open or closed attached garage, or near a home.

Features and Operation

Your new Kidde battery powered CO alarm utilizes sophisticated electronic components to protect you and your family from the dangers of CO. Unique features include red and green diagnostic lights, battery status, and sensor health. Familiarize yourself with these features:

Red Alarm Indicator Light

If a dangerous level of carbon monoxide is detected the red alarm LED will pulse and a loud (85 decibel) alarm pat- tern will sound. When the device detects Carbon Monoxide, the alarm pattern will be 4 short beeps – followed by 5 seconds of silence – followed by 4 short beeps with a corresponding red LED flash. This cycle will continue for 4 minutes and then change to 1 cycle every 1 minute until the device is reset or the CO is

eliminated. See figure 2.

See page 11-12 for an
understanding of which CO
levels are dangerous.

Light

The green light flashing every 30 seconds indicates the unit is functioning properly (see figure 3).

The green light will flash before a CO reading is taken and when any button is pressed.

If the unit chirps once every 30 seconds, observe the unit for the following:

A chirp every 30 seconds, with a green LED flash followed by a red LED flash, indicates the batteries are low. Follow the battery installation/replacement instructions on page 9 and 10.

A chirp every 30 seconds, with a red flash and no green LED flash indicates a unit error. If the unit does not respond, call the Kidde consumer hotline at 1-800-880-6788..
