The level bars are graded in 0.5 unit steps from a minimum setting of 0.0 (off) to a maximum setting of

10.0 (approximately +12 dB). Each 0.5 unit step corresponds to 1 pixel of the level bar. The default

setting for both Main and Auxiliary Volume controls is 5.0 (approximately 0 dB).

Pressing the Main Volume Control invokes loudspeaker cut. The green LED above the Reply Key is

illuminated while the loudspeaker is cut.

4.8.10 Reply Key

This DAK is designated to respond to any unscheduled calls. The green LCD indicator on the REPLY

Key only flashes to signal the presence of an unscheduled call, when a DAK is unavailable, (i.e. to

indicate that the call can only be responded to by the Reply Key).

The Reply Key can only respond to the call mnemonic displayed. All other incoming calls are placed in

a queue and have to be accessed in turn. The latest call is placed at the front of the queue. The maximum

number of calls in this queue is ten.

If the DAK is used to respond to a call, then the Reply Key displays the next call in the queue.

4.8.11 Direct Access Key (DAK)

The 4000 Series LCD Key Panels have 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.

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:

Table 33: PD4221 DAK Operation

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

engaged position. Pressing the DAK again disengages it.

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

disengages 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 Lis-

ten 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 momentary press disengages the DAK

and the latched Listen Route.
