The WPS-PL consists of:
The mechanical components:
- The call station housing is consisting of glass fibre reinforced polyester in colour RAL 2004 (orange).
- The call station housing cover is equipped with a keypad control panel. (Optional with one button or three buttons)
The electrical components:
- One electret microphone incl. compressor
- One pressure chamber loudspeaker
- One motherboard incl. 4 W call station amplifier
- One adapter board
The WPS-PL is connected to the DVS-21 through the SOS Power Supply Interface SV01-PL and SOS Line Interface NSA-PL. Up to 26 WPL-PL could be part of one SOS Line.
The voice transmission between call station and DVS-21 is carried out as SOS Line with additional transmission of control and monitoring signals and power feed in 6-wire technology.
Due to long distance power limitation, a special Sequential Search Call is implemented. After starting a Sequential Search Call by the control centre, each SOS Call Station will be announced one after another automatically.
Good/Malfunction and call signals will be indicated by implemented LED`s on the keypad.
The display and blink behaviour of the LED`s can be set up by User Software ICS of the DVS-21.
The maximum quantity of WPS-PL call stations in the SOS Line is addicted on the characteristic of the transmission medium, the distance between call stations and the operation mode.
Typical values are as follows:
|No. of WPS-PL
(Active / Idle)
|Spacing [m]||Wire diameter [mm]||No. Of wires||Max. PL length
|8 (1 / 7)||500||0.9||3 x 2||4|
|15 (1 / 14)||500||0.9||4 x 2||7,5|
|26 (1 / 25)||500||0.9||3 x 4||12|
|26 (1 / 25)||500||1.2||4 x 2||13|
Operation Button SOS:
With activity of the SOS Button, the SOS call will be initiated as a SOS emergency call to the dispatching centre SOS-DTA-LAN call station. The SOS button has the highest priority. In case of control button 1 or 2 is pressed additionally, the DVS-21 HCPU will be prohibited the call through to the line. The call request of button 1 or 2 will be signalled to the related control DTA-LAN 1 or 2. A conversation between control button 1 or 2 and DTA-LAN 1 or 2 during a SOS call with SOS-DTA-LAN is not possible!
Operation Button Control 1 + 2:
With activity of control button 1 or 2, a call will be initiated as a standard call to the related dispatching centre call station DTA-LAN 1 or 2, which is separated from the SOS-DTA-LAN call station.
The control buttons 1 and 2 have the lowest and equal priority. In case of activity control button 1 or 2 and a conversation with DTA-LAN 1 or 2 is established, the SOS call interrupts and finished this conversation.
In case of call request from control button 2 to DTA-LAN 2, during conversation control button 1 with DTA-LAN 1, the line request will be stored as long as this conversation ends and the call request from control button 2 will be acknowledged by the user of DTA-LAN 2.
In case of call request from control button 1 to DTA-LAN 1, during conversation control button 2 with DTA-LAN 2, the Line request will be stored as long as this conversation ends and the call request from control button 1 will be acknowledged by the user of DTA-LAN 1.
