TESTING YOUR CARBON MONOXIDE ALARM
The unit should be tested once a month by pressing and holding
the test button on the front of the unit for 5 seconds, this tests
the electrochemical cell, electronics and audible alarm. If the unit
is functioning correctly, the green light will stay illuminated, the
red light will flash and the alarm will sound. In case of a fault the
unit is giving visual and audible signals once per minute. These
signals can be triggered any time by pressing the test button.
Flashing red light and audible alarm
50ppm Between 60 to 90 mins
100ppm Between 10 to 40 mins
300ppm Less than 3 mins
-10˚C to 40˚C
30 to 90% RH non-condensing
Warm-up time after
initial switch on:
Normal Operating Life:
Up to 7 years
Battery life when in alarm:
At least 5 days
110mm x 76mm x 34mm
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. This
detector comes with a clear end-of-life indicator. The unit must
be replaced when a low battery warning (1 chirp per minute or
a fault warning signal (2 chirps per minute and the status light
flashing yellow) is given. It is recommended to replace the unit
after the date marked on the front of the unit.
When the unit has come to the end of its life, dispose of it in
accordance with local regulations.
BATTERY DIRECTIVE STATEMENT
For safety reasons the H450EN is a sealed unit
and the battery is not replaceable. At the end of
the unit's life, if you have any concerns over the
safe disposal of the unit/battery, please contact
your local recycling centre or the Honeywell
helpline printed in this manual.
When no Carbon Monoxide is present, the status light will flash green 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 every minute.
The Carbon Monoxide alarm can be distinguished from smoke detector alarms as it
signals C.O. in morse code (approximately 5 chirps per second).
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
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 status light
will flash green approximately once every minute again.
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.
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.
