and may be tested using a known source of CO.
Step 3:
Light a cigarette or an incense stick using a match or lighter. Extinguish
the lighter, or put out the match and place it into a dish of water.
Step 4:
Turn the alarm on its side so that the vents nearest the
Test/Reset button on the side of the alarm are pointing downward
(see diagram opposite). Hold the burning cigarette or incense stick
15 - 20 cm (6 - 8 inches) below the detector, so that the smoke
moves towards the holes in the sides of the detector.
An increase in the Carbon Monoxide level to more than 100ppm will cause the
horn to sound momentarily and the green LED to illuminate continuously for a short
time and then flash rapidly. Now move the source of CO away from the alarm (Note -
It may take up to 2 minutes of exposure to the smoke for the Carbon Monoxide levels
to reach over 100 ppm. In addition please note that the full alarm will only sound if
excessive amounts of CO are detected during this short test).
Step 5:
After step 4, put out the incense stick or cigarette by placing it into a dish of
water. Ensure that all flames have been extinguished. As the level of CO falls the green
LED will stop flashing and will again continuously illuminate for a short time.The unit will
then return to sensor test mode with the green LED flashing twice every 5 seconds.
Step 6:
After around four minutes the detector will return to normal monitoring mode
and the green LED will flash once per minute.
