CalibrationProcedure:RADCO2SafetyAlarms
Thisisamoredetailedexplanationofthecalibrationprocedurefoundinthe
manual.Checkyourstateorlocalcodeforcalibrationschedulerequirements.
Ataminimum,youshouldcalibrateatleastonceayear.
Thereare2differentcalibrationproceduresdependingonthealtitudeatwhich
thedeviceistobeused:
1. 0‐3,000ft.(900m):PerformZeroCalibrationandSpanCalibration.
2. 3,000+ft.:PerformZeroCalibrationonly.

BeforeYouBegin
1. ForZeroCalibration,youwillneedagascylinderofpurenitrogen(0ppm
CO2).ForSpanCalibration,youwillneeda2ndcylinderof4%CO2.
2. Temporarilycoverthebuzzerholeintheupperright‐handcornerofthe
SEU(sensorunit)andRDU(remotedisplayunit)withasmallpieceof
maskingtapetominimizethealarmsoundduringcalibration.
3. Ifcalibrationistobeperformedin‐situ,firstinformbuildingoccupantsthat
youwillbetestingtheCO2alarmforseveralminutes.
4. AttachincludedtubingbetweenthegascylindersandtheSEUcalibration
portasfollows:
a. RAD‐0102SX2–Connectthetubingtothesuppliedplugandsecureit
overtheairentry/calibrationportonthefrontoftheSEU.
b. RAD‐0102/RAD‐0200–Connectthetubingtothecalibrationporton
thebottomoftheSEU.

ZeroCalibration

1. Attachtubingbetweenthenitrogen(0ppmCO2)gas
cylinderandthecalibrationport.
2. Turnonthegasregulator.Flowrateshouldbe
between0.15‐0.3litersperminute.
3. WaituntiltheCO2readingontheSEUsettles
consistentlyatornear0ppmCO2onthescreen.
4. PresstheModebuttonuntilthe“CALI”iconflashes.
5. PressEntertoenterthe“Zero”calibrationmode.The“CALI”iconand
“ZEro”shouldbedisplayedonthescreen.
6. PressandholdtheModebuttonforatleast10secondsuntil“Calibrating”
and“CO2”areflashingsimultaneously.
7. Zerocalibrationwillbegin.Afterapproximately5minutes,theLCDwill
displayeither“PASS”or“FAIL”.IftheLCDreads“FAIL”,repeatthesteps
again.
8. PressEnter.Thedisplayshouldnowshow0ppm.Removethenitrogen
cylinder.

SpanCalibration
Warning:Youmustbeinawell‐ventilatedareabeforestartingSpanCalibration.
Breathing4%CO2gasinanenclosedareacanresultindizziness,shortnessof
breath,orunconsciousness.
Devicecannotbespancalibratedabove3,000ft.(900m)altitude.

1. Attachtubingbetweenthe4%CO2gascylinderandthe
calibrationport.
2. Turnonthegasregulator.Flowrateshouldbebetween
0.15‐0.3litersperminute.
3. WaituntiltheCO2readingontheSEUsettles
consistentlyatornear4%CO2onthescreen.
4. BothAlarm1andAlarm2willsound.
5. PresstheModebuttonuntilthe“CALI”iconflashes.
6. PressEnter2timestoenterthe“SPAn”calibrationmode.The“CALI”iconand
“SPAn”shouldbedisplayedonthescreen.
7. PressandholdtheModebuttonforatleast10secondsuntil“Calibrating”and
“CO2”areflashingsimultaneously.
8. Spancalibrationwillbegin.Afterapproximately5minutes,theLCDwilldisplay
either“PASS”or“FAIL”.IftheLCDreads“FAIL”,repeatthestepsagain.
9. PressEntertocompletecalibration.RemovetheCO2cylinder.
10.Toresetthealarm,youmustdisconnecttheSEUfromthepowersource.Wait
afewseconds,thenplugitbackinagain.

Ifyourunitfailseither“ZEro”or“SPAn”calibration,please
followtheprocedureagainbeforecallingsupport.
