Peak CO Concentration Memory and Reset
Be sure to test your CO alarms when you turn them on for the first time. In addition to the weekly test you should perform, it is
also recommended to test the alarm after returning from a long trip or vacation.
Type
XC01/XC05P
XC01P-R
Action
Push the test button once to wake up the alarm,
and press the test button again when the LCD is on.
Push the test button.
Device
Response
The device beeps 4 times twice, and the LED will flash red. The LCD will display
“---,” “PAS,” the peak
CO concentration recorded since the previous reset, and finally
“0.” This indicates that the device is
functioning properly.
NOTE:
The test function accurately tests the alarm’s CO sensing circuit without the need of testing CO.
The peak CO concentration feature is helpful in identifying if there have been any dangerous CO readings since a peak CO
concentration reset.
Each time you push the test button, the LCD displays the peak CO concentration recorded since the previous reset. The peak
CO concentration will be displayed for 5 seconds, and then the device will enter standby mode. In the example, 300 ppm was
the maximum CO concentration recorded since the unit was last reset.
Peak CO Concentration Reset:
During the 5 seconds when the LCD displays the peak CO concentration, press and hold
the test button for 3 seconds, the device will beep, the LED will flash green, and the peak CO concentration will be reset with
LCD displaying
“0.”
NOTE:
If the carbon monoxide concentration is lower than 30 ppm, it will not be recorded in the peak CO concentration.
Press the test button during an alarm to have the unit enter silence mode. If the CO density still exceeds the alarm threshold
after 6 minutes, the unit will enter another alarm state. Otherwise, the unit will exit the silence mode after 9 minutes and
resume normal operation. If the CO concentration is above 300 ppm, the silence function cannot be enabled.
