27. CARBON MONOXIDE ALARM
AFireAngelCO-9Bbatteryoperatedalarmistted
neartotheceilinginyourcaravan.
Features
• An advanced electrochemical sensor designed
to accurately measure low levels of carbon
monoxide (CO) providing an early warning of
toxicCOlevelsinyourcaravan.
• Detects carbon monoxide continuously.
• Resistant to false alarms caused by usual
household contaminants.
• Sounds a large 85 dB alarm (at 1 metre (3 feet))
to alert you in case of an emergency.
• Test/Resetbutton
• Simpletomount,portable,idealfortravelling
• Conforms to the British standards Institute (CSi)
CarbonMonoxideStandardBSEN50291:2001
• 7YearWarranty.
• Test/Resetbuttonfeature
• Test the sounder, batteries and circuitry
• Allowsyouto testthe sensorby introducinga
source of CO into the detector
• Silence the loud 85dB sounder during an alarm
(onlypossiblewhencurrentCOlevelislessthan
50ppm)
• Testing the sounder batteries and circuitry.
• Test the sounder, batteries and circuitry by
pressing and holding the Test/Reset button
for 1 second to conrm that the detector is
operating properly. The sounder should sound
as soon as the button is pressed, and the alarm
LED will illuminate red, indicating that the
sounder isworking and thebatteries are
providingpowertotheunit.Thetestfor
the sounder batteries and circuitry should
beperformedweekly.
• Testing the Sensor
• All sensors testing should be carried out by
a responsible adult. This test should only be
performedonceamonth.Excessivetestingwill
cause the battery life to be shortened.
Note: CO testers may be used in order to avoid
havingtoburncigarettes,incensesticksetc.
Please read all steps thoroughly before attempting
to test your alarm.
• If the alarm is wall mounted, remove by
unhookingtheunitfromthewallxingscrews.
• Coverthesounderventswithonehandandhold
the Test/Reset button down with your thumb/
ngeruntilthepowerLEDilluminatesgreenand
the sounder sounds for a second time. (This
should happen after 5 seconds.) Release the
Test/ResetbuttonandthepowerLEDwillash
green once every second. This indicates that
the sampling rate of the detector has increased
andcanbetestedusingaknownsourceofCO.
• Light an incense stick or a cigarette using a
match or a lighter. If using an incense stick, be
suretoblowtheameoutsothattheincense
stick is smouldering. Extinguish the lighter, or
put out the match and place it into a dish of
water.
• Turnthedetectoronitssidesothattheventson
the right hand side of the detector are pointing
downwards.Holdtheburningincensestickor
cigarette around 15cm (6 inches) below the
detector. An increase in the localised carbon
monoxidelevelwithinthesensortomorethan
50ppm (Parts Per Million, the accepted level
of carbon monoxide in the air) this will cause
the sounder to sound for one cycle of four loud
beeps.ThepowerLEDwillnolongerashgreen
everysecondbutwillreverttoashingoncea
minute. The detector will revert back to the
ordinary operating mode (it may take up
to two minutes for the localised level of
carbon monoxide to reach over 50ppm.)
NowmovethesourceofCOawayfromthe
detectorasthetestisnished.
• Afterstep4,putouttheincensestickorcigarette
by placing it into a dish of water. Ensure all
ameshavebeenextinguished.
Note:Ifthelocalisedcarbonmonoxidelevelwithin
thesensordoesnotreach50ppmduringthetest,
the sensor test will stop automatically after 3
minutes.
Understanding your product’s indicators
The higher the concentration of carbon monoxide
detectedbythedetector,thequickeritwillrespond.
Whensufcientcarbonmonoxideisdetectedaloud
audible signal (85 dB at 1m/3 ft) will be emitted
andtheAlarmLEDwillashredonceeverysecond.
TheAlarmwillsound:
• Between 60 and90 minutes when exposedto
50ppmofCO
• Between 10 and40 minutes when exposedto
100ppmofCO
• Within3minuteswhenexposedto300ppmor
more CO
• There will be an audible ‘chirp’ if the battery,
sensororcircuitryhasanyfaultincludingalow
battery.Thissoundwillcontinueonceaminute
for30days.(Thebattery mustbe replacedto
ensure occupant safety.)
• Ifthedevicecontinuestochirpdespitehaving
