Model as Malfunction Alert Panel:

The following describes the functionality of the DTA purely as malfunction alert panel,
i.e. without PA/intercom functionality:

Programming is done with the help of the ICS software.
For this a block of keys (the start and end keys of the block are inputted) is
established, which handles a line-on and line-off frame differently than normal line
keys.

If a special model of the DTA is used as malfunction alert panel then the physical start and end
keys can be different than those of the standard model. If a basis housing has more than 30 keys
then it is always a case of a special model. Thus the following applies
(with 36-54 keys in the basis housing): Start key = 31, end key = 66 ... 84

All status changes inside this block (on

→ off as well as off → on) are indicated

optically by different blinking lights on the associated line key. Also an audio signal
sounds with every status change.

The blinking line keys and the audio signal are a request to the user to acknowledge
the status change event by pressing the respective line key. After acknowledging, the
way the line key is illuminated changes to correspond to the current status of the
change.
If all status changes have been acknowledged then the audio signal goes silent and
is switched on again only when the next status change occurs.

All line keys in a defined block work independently of one another and can be used at
the same time. The audio signal sounds as soon as a status change occurs which
has not yet been acknowledged.
Only when all status changes have been acknowledged does the audio signal go
silent.
All line keys of the DTA call station can be operated simultaneously and
independently of one another and also be evaluated in the DVS-21 central system
simultaneously and independently of one another.

Manual check and self-test:

To check all optical and audio elements a separate key can be defined as lamp and
signal test key.
When the lamp test is activated all LEDs of the line keys are turned on to manually
check the proper functioning of the display elements.

The switching on or off of the display elements using the lamp test only has an effect on the
regular condition of the display elements during the active lamp test function.
It overrides the LED illumination only for test purposes and switches all display elements back to
their original condition after the lamp test is deactivated.
