Zone Mode; System Controller Mode - GE KTD-405 User Manual

Zone mode

A zone is a remote switching device (multiplexer or DVMRe) that serves a group of cameras. A system can be
divided into as many as 32 zones, and each zone can have from 1 to 32 cameras.
The outputs from the zone's switching device connect to dedicated monitors directly. Each zone is assigned a
device type (multiplexer or DVMRe) and a size (1 to 32 cameras) and can be assigned a 15-character name.
To call up a camera in a zone, you must know the
zone title (or number) and the camera number
(Figure 4). Refer to Zone receiver site addressing
page 53.

System controller mode

System controller mode is an extension of standard and hybrid Digiplex modes, a mode that allows use of the
KTD-405 with the HDS (High Density Switch) system controller. In this type of system, each user is assigned
a user number that determines the user's access privileges for each of the system resources. Users must log on
to the keypad using their assigned user number. The keypad uses the number to ask the system controller for
permission when the user attempts to access a monitor, camera, or other system resource. This is in contrast to
the other operation modes, where permissions are assigned to each keypad and stored in each keypad's
permanent memory.
When the installer activates system controller mode, the keypad powers up with the login menu (Figure 5).

ENTER USER ID
NUMBER: ____
Normally you will enter a user number (up to four digits) and press enter to access system control through the
keypad. Once the keypad recognizes your user ID, its displays and operations will be almost the same as in
standard or hybrid Digiplex modes. To log off the keypad, hold esc and press enter, then confirm that you
intend to log off. The display will return to the system controller mode login menu (Figure 5).
If the system controller does not recognize your user ID, the message NOT AUTHORIZED will display for a
few seconds and the display will return to the login. The same message displays if you attempt to access a
resource for which you do not have authorization.
Occasionally, you may also see the message NO RESPONSE FROM SYSTEM. This will occur repeatedly if
the system controller is not functioning or if the keypad connection to it has been broken. The message may
also appear during ongoing operations if the communication has been disrupted by other messages on the
circuit connecting keypads to the system controller. In this situation, retrying will usually succeed.
If a system controller is not available and you need to change the keypad's setup, you can access the menus by
entering the special user number 55555. This brings you to the same place as holding down the enter key for
three seconds to access menus. You must then enter the menu code as usual. The version numbers and other
system parameters are also accessible from the user code entry screen by holding down the menu key.
