Trouble shooting

The door phone can not be programmed

1. Check if you are using the right password.

2. Check if the automatic answer feature was deactivated. In this case you have

to answer the call manually at the door phone.

3. The DTMF tones your system is sending may have a too high level. Try to

program the device using an incoming external call.

The door phone does not dial

1. Check if a telephone line is connected to the device.

2. Check if the the telephone line has a open circuit voltage between 20 and 60

V dc.

3. May be that the initialisation procedure was not correctly completed. Please

call again the door phone, wait for a busy tone and try then again.

4. Check if the chime button you are using is programmed and has the correct

address.

After connecting the telephone line the device will size the line all the time

1. Disconnect the DB bus connector on the unit, may be that one of the chime

buttons has a short circuit.

2. Check if the the telephone line has a open circuit voltage between 20 and 60

V dc.

3. Disconnect and reconnect the telephone line and the external power supply if

installed. Make a new initialisation of the device.

After a telephone connection a loud feedback tone is heard at the door

phone

1. Check volume of loudspeaker and microphone.

2. Check that the microphone is in aligned with the hole in the casing.

The door opener can not be activated

1. Check if the door opener has a adequate power supply. The contact in the

door phone is a dry contact and doesn’t have power to supply the door opener.

Try to short circuit the screw contacts to see if the door opener works correctly.

2. Check if the driver contact is supplied with min. 6 Vac/dc. If the voltage is

below this value (i.e. TTL driver) the driver contact doesn’t work. In this case you

have to use an external relay unit (i.e. 1471).

3. Check is the driver contact is correctly programmed.

4. The driver contact can be activated only after a call answer and speech

detection (red LED and microphone must be on).
