CHAPTER 4: Testing and Maintenance

Weekly Testing

Push and hold the Test/Silence button on the cover until a loud alarm sounds— 4 beeps, a pause, then 4 beeps. The alarm sequence should last for 10 seconds. If the alarm ever fails to test properly, replace it immediately. If the CO alarm is not working properly, refer to Chapter 10: “Limited Warranty”.

WARNING!

The Test/Silence button is the only proper way to test the CO alarm. NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty.

NOTE: The low battery warning should last for 30 days, but you should replace the battery immediately to continue your protection.

Choosing a replacement battery:

This unit requires one standard 9V alkaline battery. The following alkaline batteries are acceptable as replacements. This list supplements the list on the carbon monoxide alarm battery door: Eveready #522 (Energizer); Duracell #MN1604, MX1604 (Ultra). You may also use a Lithium battery like an Ultralife U9VL-J for longer service between battery changes. These batteries are available at many local retail stores. Replacement batteries are commonly available at local retail stores.

WARNING!

DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be harmful to your hearing. When testing, step away when horn starts sounding.

IMPORTANT!

Use only the alkaline or lithium replacement batteries listed. The unit may not operate properly with other batteries. Never use rechargeable batteries since they may not provide a constant charge.

Regular Maintenance

To keep the CO alarm in good working order:

•Test it every week using the Test/Silence button.

•Vacuum the CO alarm cover at least twice a year, using the soft brush attachment. Test the alarm again after vacuuming.

•Replace the battery when the CO alarm “chirps” and the red light flashes once a minute (the low battery warning).

CAUTION!

DO NOT spray cleaning chemicals or insect sprays directly on or near the CO alarm. DO NOT paint over the CO alarm. Doing so may permanently damage the CO alarm.

IMPORTANT!

Household cleaners, aerosol chemicals and other contaminants can affect the sensor. When using any of these materials near the alarm, make sure the room is well ventilated.

CO5120B specifications

The BRK electronic CO5120B is a state-of-the-art carbon monoxide detector that serves as an essential safety device for households and commercial spaces. Designed with advanced technologies and features, the CO5120B ensures reliable detection of carbon monoxide, a colorless and odorless gas that can be extremely harmful or even fatal.

One of the standout features of the CO5120B is its electrochemical sensor, which is both sensitive and accurate in detecting low levels of carbon monoxide. This technology not only enhances the unit's reliability but also ensures a quicker response time in the event of a CO leak. The detector has a measurement range of 30 to 999 parts per million (PPM), allowing it to monitor a wide range of potential threat levels.

The CO5120B also comes equipped with a digital display that shows real-time CO levels, providing users with instant information about the air quality in their environment. This feature is particularly beneficial as it enables users to assess potential risks immediately and take necessary actions before escalating issues occur. The display also features a peak level memory that records the highest level of carbon monoxide detected since the last reset, aiding in diagnosing potential problems over time.

Battery backup is another critical characteristic of the CO5120B. With a 9V battery backup option, the unit continues to provide protection even during power outages, ensuring that families and occupants remain safe under any circumstances. Meanwhile, an end-of-life signal alerts users when it's time to replace the detector, ensuring long-term effective monitoring.

The CO5120B is designed with a low-profile, sleek look, allowing it to blend seamlessly into any home decor. Its simple installation process requires minimal tools, making it accessible for DIY enthusiasts and everyday users alike. The device is also equipped with an easy-to-access test/reset button, allowing users to routinely check the functionality of the unit.

Overall, the BRK electronic CO5120B is a reliable and efficient carbon monoxide detector that prioritizes safety and user-friendliness. Its combination of cutting-edge sensor technology, real-time monitoring, battery backup, and added convenience features makes it an excellent choice for anyone looking to enhance their safety against this silent threat in the home or workplace.
