When this linkage status is set to on:
● If a fire alarm (dry contact alarm) is generated, the
rear door of the IT cabinet is opened.
● When the cabinet door is opened, the ECC800-Pro
generates a door open alarm. After the fire alarm
is cleared, you need to manually close the IT
cabinet door. After the door is closed, the door
open alarm is cleared.
● If the emergency heat dissipation control logic
conflicts with the fire control logic, the fire control
logic takes precedence.
NOTE
If the fire extinguishing system is installed inside the
smart module, the linkage function is not enabled.
