Programming the Auerswald TFS-Dialog 200 door intercom

The Auerswald TFS-Dialog 200 is an analog door intercom (up to 4 bell buttons) that connects to an a/b (analog) port of a PBX. It has no web UI: everything is programmed with DTMF digits from an internal phone. This guide covers entering programming mode and every programming code from the vendor manual (V07 02/2018).

Prerequisites

• The TFS-Dialog 200 is connected to an internal analog port of the PBX and set up there with an internal number <extension> (see PBX setup).
• An internal analog phone with DTMF (tone dialling), or an ISDN phone with DTMF signalling.
• The device PIN — 0000 from the factory.

Steps

1. Enter programming mode

1. Press any bell button (short tone) and hold it for about 5 seconds until a second tone sounds.
2. Within 3 minutes, pick up an internal phone and dial <extension>. The intercom answers.

2. Authenticate and enter a code

Every function is entered as:

*   <PIN>   *   <code digits>

1. Dial * — you hear a short tone.
2. Dial the PIN, then *. Wait for the confirmation tone (five rapid beeps).
3. Dial the function code (table below). Wait for the confirmation tone again, or hang up if the function says so.

Rules:

• If you dial * and immediately hear the five-beep confirmation, the device is still in programming mode — skip <PIN>* and go straight to the code.
• Several functions can be programmed in a row without hanging up; the PIN is remembered until programming mode ends.
• Programming mode ends after more than 3 minutes without input, or when a bell button is pressed.
• A wrong input gives a 1–2 s busy tone instead of the confirmation. Start again with *.

3. Function codes

B = bell button 1–4, numbered top to bottom. Times given as 1–9 × 0.5 s mean: dial one digit, the value is digit × 0.5 s.

Bell buttons

Code	Function	Values	Default
2 B <number> then hang up	Call target of button B	up to 32 characters 0-9 * #	31, 32, 33, 34
3 B F	Switching-module frequency triggered by button B	0 none, 1–4	1, 2, 3, 4
4 B Z	Extra bell (terminals 1/2) triggered by button B	0 none, 1, 2	1, 2, 0, 0
7 B L	Button B also switches the stair light	0 off, 1 on	off

Notes on 2 (call target):

• Some PBXes need a dialling pause inside the number: stop for at least 5 s during input, a short tone confirms the stored pause.
• For no call target (e.g. to use the PBX’s baby/senior call feature), hang up right after the button digit, or wait 5 s to store only a pause.
• After this function you must call the intercom again for further programming.

Door opener and light

Code	Function	Values	Default
5 6 T	Door-opener on-time	1–9 × 0.5 s	2 s
2 6 <digits> #	Digits dialled after # during a door call to open the door	1–6 digits	#9
5 5 T	Light on-time	1–9 × 0.5 s	0.5 s
2 5 <digits> #	Digits dialled after # during a door call to switch the light	1–6 digits	#8

The door-opener and light sequences must differ.

Timing

Code	Function	Values	Default
5 1 M	Maximum talk time	1–9 min, 0 unlimited	3 min
5 2 R	Maximum ring duration	1–9 × 10 s	20 s
5 3 T	Ring delay (so repeated presses don’t restart dialling)	1–9 × 0.5 s	0.5 s
5 4 T	Pause between hang-up and re-dial (PBX hook/flash time), when powered from the a/b port	1–9 × 0.5 s	2 s

Audio

Code	Function	Values	Default
5 0 S	a/b line input sensitivity	0 low – 9 high	3
5 8 A	Ambient noise near the phones	0 quiet, 1 loud	quiet
5 7 V	Intercom speaker volume	0–9	2
5 9 S	Beep on bell-button press	0 off, 1 on	on

If the beep is off, you only hear one tone when entering programming mode.

PIN and reset

Code	Function	Notes
2 9 <new PIN> # <new PIN> #	Change the PIN	1–6 digits, entered twice. Strongly recommended.
9 1 then hang up	Factory reset	The PIN is not reset. Re-enter programming mode afterwards.

Example: ring extension <target> on bell button 1

hold bell button 1 for 5 s  →  dial <extension> on an internal phone
*          (1 short tone; if you hear 5 beeps, skip the next line)
0000 *     (factory PIN, wait for 5 beeps)
2 1 <target>
hang up

Everyday use (during a door call)

Dial	Effect
1	Force the speech path open (normally opens automatically on speech)
#9	Open the door (factory sequence)
#8	Switch the stair light (factory sequence)
##1–##4	Trigger a/b switching module with frequency 1–4
#*	End the door call (or just hang up)

Calling the intercom from an internal phone (dial <extension>) to start a door call only works when it is powered by the bell transformer, not from the a/b port alone.

Verify

Press the bell button. The phone(s) at the call target should ring within the ring delay. Answer and dial #9 (or your custom sequence) to check the door opener.

Troubleshooting

• Call is not ended after hanging up / speech path switches poorly: the intercom does not detect the PBX busy tone. Adjust the a/b input sensitivity (5 0) first. Only change the ambient and speaker volume settings if that does not help. Also make sure the PBX sends a busy tone when a call ends on that port.
• Busy tone right after a code: the input was wrong. Start again with *.
• Five beeps immediately after *: still in programming mode. Leave out <PIN>*.

PBX setup

The PBX must know the intercom as an internal subscriber before any of this works.

• Auerswald COMpact 4000, COMpact 5000/R, COMmander 6000/R/RX (firmware ≥ 6.4A): create it as a door station from the device template. The PBX then controls call targets and ring duration completely. Leave the button call targets in the intercom at their factory defaults (31–34).
• Other PBXes: create it as a normal analog extension and enable busy tone at the end of a call for that port.

Up to six optional a/b switching modules can be added to drive extra bells, a door opener or a stair light (see 3 B F).
