G. Maintenance and cleaning
There are a few steps you need do to keep it working properly:
Test the detector at least once a month.
Do not paint the detector. Paint will seal the vents and interfere with the sensor's ability to
detect smoke and/or CO.
Never attempt to disassemble the detector to clean inside. This will damage the detector
and possibly render it unuseable.
Clean the detector at least once a month to remove dust, dirt or debris. Use a vacuum
cleaner with a soft brush and vacuum all sides and covers of the detector.
Some materials, vapours or gases, can affect the reliability of the alarms in the short or long
term. Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethylacetate, hydrogen,
hydrogen sulfide and sulfur dioxide are substances that at high levels can damage the
sensor or cause temporary readings that are not CO readings. Also most aerosol sprays,
alcohol based products, paint, thinner, solvent, adhesive, hair spray, after shave, perfume,
auto exhaust (cold start) and some cleaning agents.
H. Trouble shooting
The detector does not sound when testing: Check whether the switch on the back of the
detector is in the "ON" position.
False alarms triggered intermittently or when residents are cooking, taking showers, etc.:
Check whether there is any danger from smoke or CO nearby. Once danger has been ruled
out, press the test button to set the silent mode. To prevent future false alarms, clean and
maintain the smoke detector as directed. Also consider installing the smoke detector in a
different location if it gives a false alarm due to water vapor, for example.
Alarms, beeps and/or LED lights: See LED indicator chapter.
