Description: The controller fails to start up.
This occurs only in models with the CPU control panel. When the power is switched on, the communication line between the controller and control panel fails to open properly. Or, after the start up, the communication with the controller stops. After the control panel’s power is switched on, the Attention Code (FDH) or Attention Acknowledge Code (FEH) from the controller fails to arrive. The control panel issues a command to the controller to check the communication line at intervals of 30 seconds, and the response to the command does not come back to the control panel. Since this is detected by the control panel, SC logging or CSS report cannot be performed for this.
Causes: Controller stalling. Faulty board installation. Defective controller board. Faulty connections of the harness at the control panel. Controller delay.
