Maintenance

To keep your Smoke/CO Alarm in good working order, please follow these simple steps:

•Verify the unit’s alarm, LED lights and battery operation by pushing the Test/Reset button once a week.

•Remove the unit from mounting plate and vacuum the alarm cover and vents with a soft brush attachment once a month to remove dust and dirt. R E I N S TALL IMMEDIAT E LY AFTER CLEANING AND THEN TEST USING THE TEST/RESET BUTTON.

•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 to another location 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 contaminates are used, the area must be well ventilated. The following substances can affect 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,

KN-COSM-BCA specifications

The Kidde KN-COSM-BCA is a highly rated combination smoke and carbon monoxide alarm designed to enhance home safety. This device integrates advanced technologies that provide comprehensive protection against two of the most critical household threats: fire and toxic gas exposure.

One of the standout features of the KN-COSM-BCA is its dual-sensor technology, which combines both photoelectric and ionization sensors. The photoelectric sensor is especially effective at detecting smoldering fires, which often produce a large amount of smoke without an open flame. On the other hand, the ionization sensor is more responsive to fast-burning fires, ensuring that users are alerted promptly in the event of any fire emergency. This combination ensures a higher level of accuracy in distinguishing between potential threats, thus reducing the chances of nuisance alarms.

Carbon monoxide detection is another critical component of the Kidde KN-COSM-BCA. Carbon monoxide is a colorless, odorless gas that can be lethal even in small amounts. The alarm features a powerful CO sensor designed to detect dangerous levels of carbon monoxide quickly and accurately. The device's LED display shows real-time CO levels, allowing users to be informed about their indoor air quality at a glance.

Another key characteristic of the Kidde KN-COSM-BCA is its voice alarm feature. Instead of just a series of beeps, the alarm announces the type of hazard detected, either “Fire” or “Warning: Carbon Monoxide.” This clear communication helps users quickly understand the nature of the threat, facilitating timely responses and safety measures.

The device is equipped with a hush feature to temporarily silence unwanted alarms, making it convenient during cooking or other activities that may trigger false alarms. Additionally, its battery-operated system, backed by a reliable lithium battery, ensures that the alarm remains functional even during power outages, enhancing household safety at all times.

Furthermore, the Kidde KN-COSM-BCA comes with a test/reset button, allowing users to regularly check the functionality of the unit, ensuring peace of mind. Its sleek design enables easy installation in various locations throughout the home, from hallways to bedrooms.

In summary, the Kidde KN-COSM-BCA stands out due to its dual-sensor technology, advanced carbon monoxide detection, clear vocal alerts, and user-friendly features, making it an essential addition to any safety-conscious household.
