User Instructions
IMPORTANT: Keep these User Instructions for reference.

Intended Use
The CME1-FTG is an 11L 500 ppm Aerosol Carbon Monoxide Field Test Gas that can be used with the
Macurco CM-E1 and CM-6 CO detectors. This field test gas allows installers to do a quick functionality test of
the CO sensor. The flow rate of the CME1-FTG is 10 Lpm so you will have about a minute of gas or enough to
test 20-30 sensors.
Specifications
CME1-FTG Carbon Monoxide Field Test Gas 11L 500ppm CO/Air, Aerosol, 10LPM
Field Test Procedures CM-6
Caution:
Units to be tested must be powered continuously for a minimum of 3 minutes before proceeding.
For optimum test results the unit should be in clean air and be in a low ambient air flow.
Check that the CM-6 status indicator light is illuminated, Green continuously. If not, do not proceed
with tests. See CM-6 Trouble Indicator section.
1. The display option should be set to “On” and reading 0 ppm in clean air.
2. With the cover in place, direct the gas into the housing by placing the nozzle of the aerosol can onto the
sensor grate area (under DO NOT PAINT) and press for 2 to 3 seconds.
3. Wait for a few seconds. The digital display should climb indicating the increased CO concentration at the
sensor confirming a pass of the quick test.
Note: If the Display does not change within 10 seconds, there are four possibilities:
a. The gas is empty, expired or degraded, replace the gas cylinder.
b. The gas was not directed into the housing (direct the gas into the housing by placing the nozzle of
the aerosol can onto the sensor grate area and re-test).
c. Unit needs to be re-calibrated (go through the Field Calibration Procedure and re-test).
4. Wait for the display to return to 0 ppm and configure options to desired settings.

Testing the Fan Relay
Note: The time to activate the Fan relay depends on the delay setting.
1. With the display function turned “On”, the CM-6 will show the current concentration of CO or “0” (zero) in
clean air.
2. With the cover in place, direct the gas into the housing by placing the nozzle of the aerosol can onto the
sensor grate area (under DO NOT PAINT) and press for 2 to 3 seconds.
3. When the CO concentration reaches the Fan Relay setting (35 ppm, for example) the display will flash back
and forth between “FAn” and “35”. With the display function turned ”Off”, the display does not show the CO
concentration, but will show “FAn” as long as the fan relay is activated.
Note: If the Fan relay does not close within a few seconds, there are six possibilities:
a. The gas is empty, expired or degraded, replace the gas cylinder.
b. The gas was not directed into the housing (direct the gas into the housing by placing the nozzle of
the aerosol can onto the sensor grate area and re-test).
c. The gas concentration at the sensor did not reach the Fan relay activation level. Set Fan relay to
25ppm and repeat the test.
d. Detector has Fan relay set to disable (OFF) or 100ppm. Set Fan relay to 25ppm and repeat the
test.
e. The Fan relay delay (Frd) setting is at 3 minutes. Set the Fan relay delay to zero (0) minutes.
f. Unit needs to be re-calibrated (go through the Field Calibration Procedure and re-test).
4. Wait for the display to return to 0 ppm and configure options to desired settings.
Testing the Alarm Relay
Note: The CO concentration to activate the Alarm relay depends on the setting.
1. With the display function turned “On”, the CM-6 will show the current concentration of CO or “0” (zero) in
clean air.
2. With the cover in place, direct the gas into the housing by placing the nozzle of the aerosol can onto the
sensor grate area (under DO NOT PAINT) and press for 4 to 5 seconds.
3. When the CO concentration reaches the Fan relay setting, the Fan relay should activate according to the
settings.
4. When the CO concentration reaches the Alarm Relay setting, (200 ppm, for example) the display will flash
back and forth between “ALr” and “200”. The buzzer will sound indicating “Alarm” if the buzzer is turned
“On”. With the display function turned off the display does not show the CO concentration, but will show
“ALr” when the Alarm relay is activated.
Note: If the Fan relay does not close within a few seconds, there are five possibilities:
a. The gas is empty, expired or degraded, replace the gas cylinder.
b. The gas was not directed into the housing (direct the gas into the housing by placing the nozzle of
the aerosol can onto the sensor grate area and re-test).
c. The gas concentration at the sensor did not reach the Alarm relay activation level. Set Alarm relay
to 50 and repeat the test.
d. Detector has Alarm relay set to disable (OFF) or 200ppm. Set Alarm relay to 50ppm and repeat the
test.
e. Unit needs to be re-calibrated (go through the Field Calibration Procedure and re-test).
5. Wait for the display to return to 0 ppm and configure options to desired settings.
4
Testing the 4-20mA current loop
1. With the display function turned “On”, the CM-6 will show the current concentration of CO or “0” (zero) in
clean air.
2. With the cover in place, direct the gas into the housing by placing the nozzle of the aerosol can onto the
sensor grate area (under DO NOT PAINT) and press for 4 to 5 seconds.
3. The Fan relay should activate according to the settings.
4. The Alarm relay should activate according to the settings.
5. The 4-20 mA output should ramp up from 4mA in clean air to 20mA at 200 ppm.
Note: If the 4-20mA output does not ramp up within a few seconds, there are four possibilities:
a. The gas is empty, expired or degraded, replace the gas cylinder.
b. The gas was not directed into the housing (direct the gas into the housing by placing the nozzle of
the aerosol can onto the sensor grate area and re-test).
c. Detector has 4-20 mA option set to “OFF”. Set 4-20mA option to “On” and repeat the test.
d. Unit needs to be re-calibrated (go through the Field Calibration Procedure and re-test).
5. Wait for the display to return to 0 ppm and configure options to desired settings.
