Door Station cannot Ring the Telephone
If pressing the Door station button cannot ring the local telephone, but the keypad can
answer the door station, the problem could be in the Ringer Module. Check that the ringer
cable from the Ringer Module to Comfort main PCB is connected correctly.
The problem could also be caused by a telephone or too many telephones connected in
parallel. The Ringer cannot drive an unlimited number of telephones. See
Too many
Telephone/Faulty Telephones
below.
Doorbell Chime is too loud
Remove the shunt from header JP6 on the DP03 PCB to soften the doorbell chime.
No Voice on Keypads or Telephones
If there is no voice menu heard on the keypads, use the local phone to sign in by pressing
* and user code and the # key. If the voice menu is not heard, then the voice may be
corrupted. The system still operates normally and can be armed and disarmed except that
the announcements cannot be heard. Intercom mode and recording and functions which do
not depend on the words and sentences can still work, This has been known to occur in
some systems due to unknown reasons which are being investigated. To restore the voice,
use Comfigurator to do a Vocabulary Download, selecting the voice file kate28.bin for
English. The UCM05 is required for this. If you are uncertain about which voice file to use,
contact [email protected]. The Vocab Upgrade takes more than 20 minutes.

many common intercom problems
Telephone cannot hear Voice Station or Door Station
In Voice Station or Door Station mode, if you cannot hear sounds on the keypad or Door
Station even if you keep silent, (i.e.. cannot switch to Listen Mode), but the KP or Door
Station is able to hear the telephone, try the following steps:
1
Does the problem occur only for 1 unit (keypad or Door Station)? If so it is a problem
with the wiring of the MIC wire from the affected Keypad or Door Station, or a faulty
microphone on the unit. You can check the MIC and Speaker on all keypads by using
the Keypad Intercom mode (F+8). Check that all other keypads can hear. Press a key
on other keypads to put that keypad into talk mode and check that the microphone on
that unit is working.
2
Too much background noise around the telephone can prevent the keypad or door
station from being heard. Try moving to a quieter area.
Door Station or Keypad cannot hear voice from telephone
The converse of the previous problem is the telephone voice cannot be heard on the keypad
or door station, but the keypad/Door station voice can be heard on the telephone. Try the
following steps:
1
If only 1 Keypad or Door Station is unable to hear the telephone voice, the volume
control on the keypad or Door Station may be set too low. The SPK wire on the affected
unit may be not connected properly, or the speaker may be faulty. A noisy
environment around one of the units may also prevent the telephone from getting
through.
2
If all the keypad/door stations are not able to hear voice coming from the telephone,
check “Phone Intercom Voice Level” in Comfigurator > Voice Settings. This can also be
programmed in Location 1700. This sets the gain level of the voice from the telephone
to the speakers. The values range from 0 (minimum) to 3 (maximum). Any value
higher than 3 is taken to be 3 (maximum). Reset is not required. The default level is 2.
