Figure 23 - PD4206 Front View

4.4.1 Direct Access Key (DAK)

The 4206 Extension Panel has twenty Direct Access Key (DAK) pushbuttons. These DAKs are used to

make Listen and/or Talk routes to and from the Control Panel or other audio connections. The DAK can

also be assigned to trigger a control event from either the Control Panel or the matrix.

There is a rotary switch inside the panel to select which bank of twenty keys it controls in the range 33 -

112. For further details please refer to the installation manual.

The pushbutton operation is selectable from a range of options and set via the Configuration and Master

Assignment Programming System (CMAPSi) workstation software. The pushbutton actions include:

1 Direct Access Key (DAK) 3 Listen Tally LED

2 Talk Tally LED 4 Designation Strip

Table 25: PD4206 DAK Operation

Latch When a DAK is pressed and released, it latches in the engaged posi-

tion. Pressing the DAK again disengages it.

Non-Latch When a DAK is pressed and held depressed, it automatically disen-

gages when released.

Latch/Non-Latch A combination of the two above such that a quick press will latch the

button and a slow press will be the non-latch action.

Dual Talk/Listen When a DAK is momentary pressed, it makes a latched Listen Route.

The DAK can then be pressed and held to make a Talk Route at the

same time, and released to unmake the Talk Route. A second momen-

tary press disengages the DAK and the latched Listen Route.

Interlock Group A DAK can be assigned to any one of eight interlock groups A - H.

Within an interlock group only one DAK may be active at any one time.

If a DAK in a given group is pressed whilst another DAK in the same

group is already active the currently active key is deactivated and the

key pressed becomes active.
