The Direct Access Keys can be programmed with a range of attributes as set in the Configuration and

Master Assignment Programming System (CMAPSi) workstation software. The pushbutton attributes

are:

NOTE: For the above functions, the destination can be a single or group of panels, or a single or group

of external sources.

Table 31: PD4212 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.

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 cur-

rently active key is deactivated and the key pressed

becomes active.

Table 32: PD4212 Pushbutton Attributes

Talk Only A single DAK press causes an audio route to be made

from the source panel to the desired destinations. Nor-

mally used for communication from one panel to another.

Listen Only A single DAK press causes an audio route to be made

from the destination. Used when listening to an external

audio signal (not originating from a Control Panel) is

required.

Talk and Listen A single DAK press causes a bi-directional audio route to

be made between the source panel and the destinations.

Used between panels and also with certain external audio

signals.

Talk & Forced

Listen

This is similar to Talk and Listen except that the Listen

route is permanently made. The operator need only press

the DAK to talk.
