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.
