Page 3
The MD PBX KEY CW doorstation can be connected to any standard analogue telephone
line, in normal cases to an extension line of a PABX. The unit is delivered in four different
versions: the BG version for installation behind existing panels, the MD version with a
designer aluminium case, the AV version with a vandal proofed aluminum panel and the
ES version with a stainless steel casing.
The connection of the doorstation to the telephone switch is done using two wires.
Further a 12 Vac power supply is needed for the door opener and the illumination lamp
in the doorstation. For this another two wires are necessary. We suggest in any case to
provide an illumination of the doorstation as the lamps heat will ensure that the
condensing water formation and a too low operating temperature can be prevented.
Please take care that in some extrem enviroment situations the unit might need an
optional heating element. The device is deliverd with microphone and loudspeaker. The
volume of the loudspeaker and the microphone can be regulated.
The unit can call different telephone numbers using to keypad and the input of a speed
dial code. The stored numbers can have up to 16 digits lenght, including dial pauses if
needed. The speed dial code input is activated using the "Speed dial code" button. After
this a two digits long code has to be dialed using the keypad. The unit will then dial the
stored number on the telephone line. The dial can be made using rotary dial pulses or
DTMF tones. The telephone numer is programmed using a DTMF dial procedure. The
digits 0 to 9 can be programmed as part of the telephone number. The digit # is used
as a dial pause. The same DTMF dial procedur is also used for all other programmations.
Only the setting for the hardware timer and the programming enable are done using
jumpers on the board.
If needed the unit can also be called. After the auto answer the unit will send a
acknowledge tone. If the programming enable jumper is set on on a programming
session can be started dialing a DTMF tone within 6 seconds after the call answer. If no
digit is dialed the unit will switch to speech modality after a second acknowledge tone.
After dialing a telephone number and the call answer from the called party a normal
conversation is possible with the doorstation using the handsfree device. At the end of
the conversation the called party can activate one or two (optional) different contacts,
i.e. to open a door.
The MD PBX KEY CW will automatically terminate the call if one of the following events
will happen:
- after dialing a speed dial code with no programmed telephone number;
- if the pause between the input of the digitis is longer then 7 seconds with incomplete
dial;
- after a programmable number of calls (1 to 99) with no answer;
- if the called party will send during the conversation the DTMF digit 3;
- after activating one of the two door opener contacts;
- with reconizing a busy tone (called party is busy or has hang up);
- after a programmable timeout (0 to 99 seconds) with no speech on the line;
- after a programmable timeout (0 to 999 seconds);
- after the timeout of a hardware timer (settable for 2, 4 or 4 minutes)
Further the unit can also activate one or two (optional) contacts using the dial of a
special access code on the keypad. This function is activated using the button "Acccess
