Table 3: PD4215 DAK Operation

When a DAK is pressed and released, it latches in the
engaged position. Pressing the DAK again disengages it.
When a DAK is pressed and held depressed, it automati-
cally disengages when released.
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 (default setting).
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 (the latched listen route remains
open). A second momentary press disengages the DAK
and the latched Listen Route.
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.

Table 4: PD4215 Pushbutton Attributes

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.
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.
A single DAK press causes a bi-directional audio route to
be made between the source panel and the destinations.
Often used between panels and external audio signals.
This is similar to Talk and Listen except that the Listen
route is permanently made. The operator need only push
the key to talk.
