2.3.2 Display board (T-PDC)
The display board may mount either inside the enclosure door so its buttons are accessible with the door
closed or on the chassis assembly (MBC or MBCLC only) so it is accessible after unlocking and opening
the enclosure. When the PDC is mounted on the door and connected to the keyswitch, the keyswitch
must be activated to enable keypad access to the system’s security-sensitive control functions.
2.3.3 Network Communications adapter (T8000-NCA)
The network communications adapter is used with each panel in a networked system. It allows the
connected panel to communicate with other panels on the panel network.
