6. TESTING & MONITORING YOUR CO ALARM
Button Test
It is recommended that you test your CO Alarm after installation and then once a week
to make sure the unit is working. It will also help you and your family to become
familiar with the sound of the alarm.
Press and hold the test button until the alarm sounds (it may take up to 5 seconds)
and the green or red light flashes. The alarm will stop sounding shortly after the
button is released. If there is a problem follow the checklist below.
Power On Indicator
Regularly check that the green power light flashes every 45 seconds - the unit cannot
work without a good battery, properly connected.
Low Battery Indicator
If the unit beeps and the green light flashes simultaneously every 45 seconds, then the
three batteries are depleted. Check the ‘Replace by’ label on the side wall - if it has been
exceeded replace the entire unit. If it has not be exceeded and the batteries are
accessible (after the battery door is removed - see figure 5a page 15) replace the
batteries. Use only the following Alkaline AA size batteries: Duracell MN1500,
Panasonic LR6, GP 15A, Ever Ready LR6 or Energizer E91. (See section 5.2 - page
16, if the locking rivet(s) has been inserted). Insert the new batteries with the
orientation shown on the base. Button test the alarm to check the batteries are installed
correctly and that they are not depleted. Slide back on the cover.
