DTA-012/030
Desk Call Station, 12/30 Illuminated Buttons
The DTA-012 and DTA-030 are the smallest desk call stations in the ProCom series.
These two models differ only in terms of the number of keys and are otherwise built
identically.
The call stations of the DTA series are designed for 4-wire connections and use in
sealed rooms (control centres and rooms, switching rooms, etc.).
At a Glance:
• 12 or 30 illuminated buttons
• Connection using plug-in cable
• Freely programmable key functions (e.g. louder/softer and

Data Sheet
DTA-012/030
Desk Call Station, 12/30 Illuminated Buttons
The DTA-012/030 consists of:
o The three-part grey-white desk housing made of ABS (RAL 9002) and the
aluminium mounting plate
o The electrical components:
- Gooseneck microphone (mounted in the cover)
- 4 W/6 W loudspeaker (mounted on aluminium plate)
- Motherboard with 4 W call station amplifier (mounted in housing base)
- Keypad circuit board (mounted on aluminium plate)
Included with the product are:
- DTA connecting cable 2.5 m
- Wall connection socket
In order to commission a DTA a connection cable is plugged in between the call
station and the wall connection socket. The wall connection socket is mounted on the
wall with 2 screws. The cable from the DVS-21 central system is set up through 4 or
6 plug contacts.
The DTA-xxx are connected through the analogue low frequency (LF) interface
module 4NSA.
Voice transmission between the call station and DVS-21 is analogue. Control and
data transmission is handled by a microcontroller. Transmission is carried out with a
modem connection.
Busy indication, voice acknowledgments and call signals are indicated by the LEDs.
The display and blink behaviour of the LEDs can be programmed with the system
software ICS of the DVS-21.
