The standard Ei Electronics Carbon Monoxide alarm pattern is a repeating cycle of 3 sound
pulses followed by a pause to help distinguish it from the Fire alarm pattern which is a
continuous rapid pulsing sound.
WARNING: If your Carbon Monoxide Alarm sounds (even if you are unsure of the cause), it
has detected dangerous levels of carbon monoxide. Always evacuate the dwelling.
NEVER IGNORE THE ALARM !
Pre-Alarm
When the Alarm detects over 43 ppm CO, the red light flashes in accordance with
Table B. This helps locate CO leaks as the CO Alarm gives an indication straight away.
(Without this feature the CO level would need to be at 43 ppm CO for typically 72 minutes for an
alarm sound to be given). Note the Pre-Alarm signal may be triggered by CO coming for example,
from cooking with gas, from car engines or from nearby barbecues. This is usually not a concern,
unless the pre-alarm signal persists until the Alarm sounds and the CO source is unknown.
The display models will display CO concentrations greater than 20ppm in accordance with
Table B.
NOTE: The CO Alarm may sound if cigarette smoke is blown into it, or aerosols are released
nearby.
