Quick Gas Test

A butane cigarette lighter can be used to perform a functionality test of the RD-12. This test allows installers to do a quick functionality
test of the gas sensor.
1. Units to be tested must be powered continuously for a minimum of 3 minutes before proceeding.
2. For optimum test results, the unit should be in clean air and be in a low ambient air flow.
3. Check that the RD-12 status indicator light is illuminated, green continuously. If not, do not proceed with tests. See RD-12
Trouble Indicator section in these User Instructions.
4. The display option should be set to "On" and reading 0 ppm in clean air.
5. With the RD-12 cover on, aim the lighter into the sensor grate area (under "DO NOT PAINT") on the front cover and release the
gas (without igniting the flame) for 1 second or less
6. Wait for a few seconds. The digital display should climb indicating the increased gas concentration at the sensor confirming a
pass of the quick test.
Note: If the Display does not change within 10 seconds, consider these possibilities:
a. Lighter is empty.
b. Detector needs servicing (return unit to factory for servicing).
7. Wait for the display to return to 0 ppm and configure options to desired settings.
