General Maintenance, General CO Information

General Maintenance

•Never use detergents or other solvents to clean the unit.

•Avoid spraying air fresheners, hair spray, or other aerosols near the Smoke/CO Alarm.

Do not paint the unit. Paint will seal the vents and interfere with the sensor’s ability to detect smoke and CO. Never attempt to disassemble the unit or clean inside. This action will void your warranty.

Move the Smoke/CO Alarm and place in another loca- tion prior to performing any of the following:

•Staining or stripping wood floors or furniture

•Painting

•Wall papering

•Using adhesives

Storing the unit in a plastic bag during any of the above projects will protect the sensors from damage. Do not place near a diaper pail.

WARNING: Reinstall the Smoke/CO Alarm as soon as possible to assure continuous protection.

When household cleaning supplies or similar contami- nates are used, the area must be well ventilated. The fol- lowing substances can effect the CO sensor and may cause false readings and damage to the sensor: Methane, propane, iso-butane, iso-propanol, ethyl acetate, hydrogen sulfide, sulfide dioxides, alcohol based products, paints, thinner, solvents, adhesives, hair spray, after shave, perfume, and some cleaning agents.

Carbon Monoxide Safety Information

General CO Information

Carbon monoxide (CO) is a colorless, odorless, and tasteless poison gas that can be fatal when inhaled.

Carbon Monoxide Safety Information

CO inhibits the blood’s capacity to carry oxygen.

Possible Sources

CO can be produced when burning any fossil fuel: gaso- line, propane, natural gas, oil and wood. It can be pro- duced by any fuel-burning appliance that is malfunction- ing, improperly installed, or not ventilated correctly. Possible sources include furnaces, gas ranges/stoves, gas clothes dryers, water heaters, portable fuel burning space heaters, fireplaces, wood-burning stoves and cer- tain swimming pool heaters. Blocked chimneys or flues, back drafting and changes in air pressure, corroded or disconnected vent pipes, and a loose or cracked furnace exchanger can also cause CO. Vehicles and other com- bustion engines running in an attached garage and using a charcoal/gas grill or hibachi in an enclosed area are all possible sources of CO.

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, heavy air in the vent pipes (cold/humid air with extended periods between cycles), negative pressure dif- ferential resulting from the use of exhaust fans, simulta- neous operation of several fuel-burning appliances com- peting 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, extend- ed operation of unvented fuel-burning devices (range, oven, fireplace, etc.), temperature inversions which can trap exhaust gasses near the ground, car idling in an open or closed attached garage, or near a home.

KN-COSM-B specifications

The Kidde KN-COSM-B is a sophisticated combination of a smoke detector and carbon monoxide (CO) alarm, designed to enhance safety in residential and commercial spaces. This dual-function device provides peace of mind by safeguarding against two of the most dangerous threats in any environment: fire and carbon monoxide poisoning.

One of the most notable features of the Kidde KN-COSM-B is its advanced photoelectric smoke sensing technology. This type of sensor is known for its quick response time to smoldering fires, which often generate large amounts of smoke without visible flames. This means that the device can alert users to potential fire hazards before they escalate, providing critical extra minutes for evacuation.

In addition to its smoke detection capabilities, the Kidde KN-COSM-B is also equipped with a reliable electrochemical CO sensor. Carbon monoxide is a colorless, odorless gas that can be produced by common household appliances like furnaces, water heaters, and gas stoves. The alarm features a loud 85-decibel warning signal, ensuring that occupants are alerted to the presence of CO promptly, allowing for immediate action to be taken.

The device is powered by a sealed lithium battery, which eliminates the need for constant battery changes, a feature that enhances its reliability. The battery has a lifespan of up to 10 years, aligning with the recommended replacement interval for smoke and CO alarms.

User-friendly features make the Kidde KN-COSM-B even more appealing. The unit includes a “test/reset” button, allowing users to easily verify the functionality of the alarm or silence it if necessary. It also features an end-of-life warning that alerts users when it's time to replace the unit, ensuring that safety remains uncompromised.

Another noteworthy characteristic is its sleek, compact design, which allows for seamless integration into various home décor styles without being intrusive. The device can be mounted on walls or ceilings, providing versatility in installation.

Overall, the Kidde KN-COSM-B stands out as a reliable solution for protecting families and properties from the dangers of fire and carbon monoxide. Its comprehensive features, coupled with user-friendly technology, make it an essential addition to any safety-conscious household.
