It is recommend to manually perform testing once a week. To perform a manual test, simply
press the test button for 1 second and the alarm will enter test mode.
All three LEDs will flash once and alarm will sound 2 cycles of 4. The LCD screen will read
"---" to indicate it's testing.
All LEDs and the LCD display should resume back to normal after a few seconds.
The alarm will perform self-checking of the sensor every 2 minutes. Under normal
conditions, no LEDs will flash. If the sensor fails, the amber fault LED will flash once every
2 minutes together with two long beeps. Also the LCD will display the error message as
below; this indicates the alarm sensor or circuitry has failed. Please stop using the alarm
immediately.
The error can be caused by either loose connections on the circuitry, short circuit or sensor
contaminated by other strong chemical fumes. If the error remains, please replace the
alarm immediately to remain protected from carbon monoxide.
The red alarm LED will only flash when the carbon monoxide count reaches an alert level
and activates the alarm. Under normal conditions the carbon monoxide count should be
below 25ppm. Therefore when the count is below 25, the LCD will only display 0ppm and
the temperature reading in a 30 second cycle.
To meet EN50291 standards, the alarm will activate within following time limits when
different critical CO level is met.
