Power conservation Mode:
When the available power is between 8 VDC and 6 VDC, the microprocessor is
programmed to place the detector into Power Conservation Mode. In this mode the
detector is capable of neither sensing nor providing an alarm to dangerous
concentrations of LP gas. The detector conserves the remaining available power by
reducing its power consumption to approximately 10 milliamps (10mA). In this
mode, the detector will emit 3 quick “chirps” once and flash RED/ORANGE
repeatedly every 3 minutes.
Low Power Alarm Mode:
When the available power falls below 6 VDC, the LED will display a steady RED
LED. This condition will remain until power is depleted or restored to a level
exceeding 10 VDC. Again, in this mode the detector is neither sensing nor providing
an alarm to dangerous concentrations of LP gas. If after restoring available power
to a level in excess of 10 VDC, the detector stays in this steady RED LED mode
(even after pressing the TEST button), return the detector to the Atwood Service
Center. This is an indication of possible microprocessor failure.
The power management functions of the Atwood Detector are designed to make
the most efficient use of available power and to provide the user with the maximum
protection through district warnings and alarms.
Power Failure
If no power is applied to the unit or there is a failure of power circuits, there will be
no identification from the LED. If there is no indication from the LED, but the audible
alarm sounds when the TEST button is pressed, then the LED is defective and the
user must contact the Atwood Service Center.
