Indication
The alarm will emit 2 sets of
four quick beeps every 5.8
seconds.
The LED will flash red
during the audible signal.
The LCD will display ―---,‖
―PAS,‖ the peak CO
concentration recorded since
the previous reset, and
finally ―0.‖
After testing, the alarm will
automatically enter standby
mode.
The initiatingunit will beep
continuously with the LED
flashing red.
Other interconnected alarms in the
network will receive the signal
after 5 seconds, then they will
beep continuously with theLED
flashing red and green
successively. Release the
Test/Silence button on the
initiating unit and all the units
will stop testing.
The units testing should be
completed within 3 minutes.
After testing, the units will
automatically enter standby mode.
NOTE:
The test function accurately tests the alarm’s CO sensing circuit without the
need totest
with CO
. If your CO alarm fails to emit an audible test signal, refer to the
troubleshooting guide at the end of this manual immediately.
Peak CO Concentration Memory and Reset
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
