CARE AND MAINTENANCE OF ALARM
The Carbon Monoxide alarm is pre-calibrated at the factory and
requires no maintenance other than to clean the outside case
occasionally with a clean tissue. Ensure that the holes on the
front of the unit are not blocked with dust or dirt. DO NOT USE
CLEANING AGENTS, BLEACH OR POLISH.
END OF UNIT LIFE
The unit will operate for up to 7 years under normal use. The unit
must be replaced when either the end of life signal is given (buzzer
sounds 3 times per minute) or a fault warning signal (1 or 2 chirps
per minute) is given.
When the unit has come to the end of its life, dispose of it in
accordance with local regulations.
OPERATION OF THE ALARM
When no Carbon Monoxide is present, the green power light will flash approximately
once every minute.
During normal operation the unit carries out a self-check test every 5 minutes.
When the unit detects Carbon Monoxide, it will give the alarm signal continuously. The
red alarm light will flash and the buzzer will sound approximately 5 chirps per second.
When the unit has been in alarm for 30 minutes the full alarm signal will be given once
The Carbon Monoxide alarm can be distinguished from smoke detector alarms as it
signals C.O. in morse code (approximately 5 chirps per second).

marked 'Test'. The red alarm light will continue to flash 5 times per second.
If Carbon Monoxide is still present after the 5 minute hush period, the audible alarm will
NOTE: The hush facility will not operate at levels above 350ppm Carbon Monoxide. At
levels below 350ppm the hush facility will only operate once, ie the audible alarm can
only be silenced for one 5 minute period.
Return to Normal Operation
When the Carbon Monoxide gas disperses, the alarm signal will stop. The green power
lamp will continue to flash approximately once every minute.
If a fault is detected the buzzer will sound 2 short chirps every minute. The unit must
then be replaced.
Battery Fault Warning/End of Battery Life
The buzzer will sound 1 short chirp every minute.
End of Unit Life
When the unit comes to the end of its life the buzzer will sound 3 short chirps every
minute. The unit must then be replaced.
NOTE: With normal use the batteries will last for up to 7 years. However, battery life will
be reduced if either a fault occurs with the battery or the unit remains in alarm for long
periods of time. Should the Battery Fault Warning occur please contact your supplier.
