Aico Ei261DENRC - Manual (Page 22)

The Fast CO Test Mode normally does not activate the memory function unless a high level of CO
remains in the sensor for a few minutes. (This can be checked by pressing the Test/Hush button. If the
red light flashes continuously (indicating CO was detected), hold the Test/Hush button for 20 seconds
until the red light stops flashing as the memory resets).
6. HOW TO DISTINGUISH BETWEEN CO ALARM & SMOKE ALARM WARNINGS
The CO Alarm has a distinctive on-off sound of 3 pulses followed by a pause, as compared with a typical
Smoke/Heat Alarm which has a rapid pulsing sound.
In addition, when your CO Alarm is sounding, the red alarm light on the cover will be flashing.
Testing both your CO Alarms and Smoke/Heat Alarms weekly will help you and your family to clearly
distinguish between them in an emergency.
If CO Alarms and Smoke/Heat Alarms are interconnected (and are all sounding), press the LOCATE
switch on the Ei1529RC Remote Control to leave just the alarm that has triggered the system sounding.
7. MAINTENANCE
Clean the outside case by occasionally wiping with a clean damp cloth (disconnect the mains supply at
the distribution/fuse board first). Do not use any cleaning agents, bleaches, detergents or polishes,
including those in aerosol cans. Avoid spraying air fresheners, hair spray, paint or other aerosols near the
CO Alarm. Do not place air fresheners near the unit.
Use the narrow nozzle of a vacuum cleaner to remove dust and other contamination from the gas entry
holes in the cover of the Alarm to ensure CO gas can reach the sensor.
Do not paint the CO Alarm.
Remove the CO Alarm when decorating. Do not allow water or dust to contaminate the alarm.
Do not open or tamper with the CO Alarm. This can damage the unit and may expose the user to shock
or fire hazards. There are no user serviceable parts inside apart from the sensor module - see overleaf.
