● If all smart cooling products fail to communicate,
and the temperature in the cold aisle is greater
than or equal to the preset value (30°C by default),
the rear door of the IT cabinet automatically opens.
● If the rear door of the IT cabinet is open and the
temperature in the cold aisle is higher than the
preset value (35°C by default), the front door of
the IT cabinet automatically opens.
● If at least one smart cooling product is in cooling
mode or the temperature in the cold aisle is lower
than the preset temperature (30°C by default)
minus 2°C, the ECC800-Pro reports a critical alarm
to remind the customer to close the door manually.

● If a smoke alarm is generated, the rear cabinet
door is opened.
● When the cabinet door is opened, the ECC800-Pro
generates a door open alarm. After the smoke
alarm is cleared, you need to manually close the
door. After the door is closed, the door open alarm
is cleared.

conflicts with the smoke alarm control logic, the
smoke alarm control logic takes precedence.
