LED indicators
Green LED: When connected to the mains supply, the alarm goes
through a 40 second initialization routine. After
initialization, the GREEN LED remain permanently on
indicating normal operation.
If GREEN LED flashes every 33 seconds, it indicates the
alarm is being powered by the back-up battery.
Red LED Flashing: When the alarm senses CO gas, it goes into alarm
mode and the RED LED flashes 4 times at 5 second
intervals.
Yellow LED Flashing: Flashing once every 33 seconds approx.
accompanied with a chirping sound indicates low
battery warning.
If flashing approximately twice every 38 seconds with
two chirps, indicates a fault condition.
Alarm Mode
In alarm mode, the CO alarm will sound four beeps in quick succession,
followed by a 5 second pause. This pattern is then repeated.
Test/Silence Button
• Use the Test/Silence button to test the alarm weekly. Please refer to
“ Testing the Alarm”.

triggered the alarm, particularly if CO alarms are interlinked
with smoke/heat alarms. Therefore, evacuate the property
first, then determine the cause and take appropriate action.
Note: The CO alarm will return to normal operating mode once the
CO gas condition is cleared.
Warning: This device alarms only on the detection of carbon Monoxide
gas. If ignored, the presence of Carbon Monoxide can be fatal.
DANGER: If the alarm sounds, and it is not being tested, it means the unit
is sensing Carbon Monoxide gas, THE SOUND OF THE ALARM
REQUIRES YOUR IMMEDIATE ATTENTION AND ACTION.
