CHAPTER 4: TESTING AND MAINTENANCE
WEEKLY TESTING
Push and hold the Test/Silence button until a loud alarm sounds— 4 beeps, pause, 4 beeps. This sequence should last for 10 seconds. If the Alarm ever fails to test properly, replace it immediately. If the Alarm is not working properly, refer to “Limited Warranty”.
•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.
•DO NOT stand close to the Alarm when the horn is sounding. Exposure at close range may be harmful to your hearing. When test- ing, step away when horn starts sounding.
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.
Household cleaners, aerosol chemicals and other con- taminants can affect sensor. When using any of these materials near Alarm, make sure room is well ventilated.
DO NOT spray cleaning chemicals or insect sprays directly on or near the Alarm. DO NOT paint over the Alarm, this may permanently damage the Alarm. DO NOT expose the Alarm to strong fumes such as painting or fumigating.
THE LOW (OR MISSING) BATTERY WARNING:
The horn will “chirp” once a minute and the word “bat” will flash on and off on the display.
NOTE: You should replace the battery immediately to continue your protection.
LOW BATTERY SILENCE FEATURE. If AC power is on, press the Test/Silence button to silence the low battery “chirp” for up to 8 hours. The alarm will continue to operate as long as AC power is supplied. However, replace the battery as soon as possible, to maintain protection in event of a power outage.
Choosing a replacement battery: This unit requires one standard 9V alkaline battery. The following alkaline batteries are acceptable as replacements. This list sup- plements 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
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.
Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.
