Operating/Installation Instructions

Step 3

Testing the Alarm

The test button has three purposes. It tests the unit’s electronics, resets the alarm and activates the peak level memory (See page 16).

CAUTION: Due to the loudness (85 decibels) of the alarm, always stand an arms length away from the unit when testing.

•To test: Press the test/reset button for five seconds and a series of beeps will sound, followed by the message “Fire! Fire!”, then another two series of beeps and the message “Warning! Carbon Monoxide”, followed by 4 additional short

beeps.

•Reset: If the the Smoke/CO Alarm is sounding a CO alarm, pressing the test/reset button will silence the alarm. If the CO condition that caused the alert con tinues, the alarm will reactivate. Reactivation times depend on the amount of CO present. See page 19.

•Peak Level Memory: If 8 chirps are made when pushing the test/reset button, the unit has detected a CO level of 100 PPM or greater.

The unit needs to be tested weekly! If at anytime it does not perform as described, verify the three batteries are installed correctly and that they don’t need replacing. Clean dust and other buildup off the unit. If it still doesn’t operate properly call the Consumer Hotline at 1-800-880- 6788.

Operating/Installation Instructions and What To Do If The Alarm Sounds

Step 4

Peak Level Memory

If the CO sensor has detected a CO level of 100 PPM or higher since last reset, it will be recorded by the Peak Level Memory function.To access the Peak Level Memory press the test/reset button. If a reading of 100 PPM or higher has been recorded the unit will chirp 8 times. If you’ve been away from home this feature allows you to check if there was a CO reading of 100, or higher, during your absence. Pushing the test/reset button resets the memory. It’s also reset when batteries are removed.

What To Do If The Alarm Sounds

NEVER IGNORE THE SOUND OF THE ALARM! Determining what type of alarm has sounded is easy with your Kidde Combination Smoke/CO Alarm. The voice message warning system will inform you of the type of situation occurring. Refer to the Features sec- tion on page 4 for a detailed description of each alarm pattern.

When the smoke alarm sounds:

Smoke alarms are designed to minimize false alarms. Cigarette smoke will not normally set off the alarm, unless the smoke is blown directly into the alarm.

Combustion particles from cooking may set off the alarm if located too close to the cooking area. Large quantities of combustible particles are generated from spills or when broiling. Using the fan on a range hood which vents to the outside (non recirculating type) will also help remove these combustible products from the kitchen.

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.
