SCREEN MESSAGES :
REASON FOR SENSOR FAULT:
Faults can be caused by broken circuitry, a faulty sensor or faulty electronic parts.
SENSOR FAULT CAUSED BY CHEMICAL GASES:
When volatile chemical gases such as alcohol are the cause for error detection, this may be corrected by
switching the detector off and leave it in fresh air for 24 hours. This will restore the sensor. If the error
is not cleared after these 24 hours, the detector is faulty and should be replaced. Don’t repair the
detector yourself, but have it repaired by the importer.
When the alarm is contaminated and damaged by high concentrations of chemical gases, the sensor could
be affected. This will lead to a temporary error or permanent damage. When the alarm sounds and you
can smell a chemical gas, this could be the reason. Carbon monoxide is a colourless and odourless gas.
Chemical gases do have an odour.
The following substances and gases can cause false alarms or permanently damage the detector:
Methane, propane, iso-butane, ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, acid, ether,
hydrogen, hepatic gas, sulphur dioxide, aerosol, propellant, alcohol preparation, paint, thinner, dissolvent,
bonding agents, shampoo, aftershave balm, perfume, car exhaust (cold start) and certain cleaning agents.
MAINTENACE:
• To keep your CO detector in proper working order, please follow these easy steps:
• Once a month, check that the alarm is working properly by pressing the test button.
• Clean the CO detector with a vacuum cleaner or with a soft cloth or brush once every month to remove excess dust.
