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 6.5 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.
DISPOSAL
When the unit has come to the end of its life, dispose of it in
accordance with local regulations.
Normal Operation
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 minute.
Alarm Condition
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 times per second.
When the unit has been in alarm for 30 minutes the full alarm signal will
be given once every minute.
Alarm Signal
The Carbon Monoxide alarm can be distinguished from smoke detector
alarms as it signals C.O. in morse code (5 per second).
Hush Feature
If required, the audible alarm can be silenced for 5 minutes by pushing
the button 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 sound.
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.
Fault Warning
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.
WHAT TO DO WHEN THE ALARM SOUNDS
If the unit raises an alarm, proceed as follows:
• Open all doors and windows to ventilate the area and allow the
Carbon Monoxide to disperse.
• Where possible turn off all fuelled appliances and stop
using them.
• Evacuate the property leaving the doors and windows open.
• Ring the gas or other fuel supplier on their emergency number
and explain the problem. Keep the telephone number in a
prominent place.
• Do not re-enter the property until the alarm has stopped.
• Get medical help immediately for anyone suffering from the
effects of Carbon Monoxide poisoning such as headaches,
nausea, etc. and advise that Carbon Monoxide poisoning
is suspected.
• Do not use the fuel burning appliances again until they
have been checked and cleared for use by a competent
person according to national regulations.
