If this linkage status is set to on:
● If all smart cooling products communicate properly
but do not provide the cooling function, 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 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
for door closing to remind the customer to close
the door manually. The alarm is cleared after the
door is closed.

If this linkage status is set to on:
● When 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.
● If the emergency heat dissipation control logic
conflicts with the smoke alarm control logic, the
smoke alarm control logic takes precedence.
