Connecting an extra door opener relay
A door opener relay can optionally be connected to the external unit between
terminals R and P. This relay must be present in the following cases:
• if several external units are used
• if the external unit is to be provided with a local door opener contact
4. PROGRAMMING and OPERATION
Programming the bell push-button
• Programming of the bell push-buttons is described in detail in the manual
of the system power supply (10-801, 10-802 or 10-806) or of the service
unit (10-870).
• If you use the service unit, tear off the serial number to be found behind the nameplate under the white foil of the external unit or the packing box, and stick
it on the installation diagram.
• You can program up to 2 internal units in the memory location of each bell push-button. If you want to program more internal units, you will need to apply
master-slave progamming to the internal units, as described in the service unit or internal unit manual.
• A non-programmed bell push-button will switch the light relay of the power supply.
General operation
If everything has been connected correctly and power up is applied, the LED of the external unit will light up.
When picking up the receiver of an internal unit, communication with the external unit should be possible at all times.
If you press a:
• non-programmed bell push-button, you will hear a high beep and the light relay of the power supply is operated
• programmed bell push-button, you will hear the bell ringing at the external and the internal unit.
Adjusting the volume on the external unit
There are 2 potentiometers under the nameplate with which you can adjust the volume on the external unit.
Potentiometer for loudspeaker (volume on external unit)
Potentiometer for microphone (volume on internal unit)
Setting times
By default, the following times are programmed:
Speech time after initiating a call .............................................. max. 2 min
Time that a call from an external unit remains indicated .............. 2 min
You can also set other times via
• the power supply. For more information on programming via the power supply, see manual of the power supply.
• the service unit. For more information on programming via the service unit, see manual of the service unit (10-870).
• the relay

5. PRODUCT MAINTENANCE

With the following maintenance tips Niko wants to prevent the surface of your product being damaged due to improper
handling.
• Clean the product with a little soap and a damp cloth.
• Never use:
- abrasive sponges or abrasive detergents;
- maintenance products containing solvents or acids, or cleaning products containing acetic acid
Damage by improper handling is not covered by the guarantee.
6. TROUBLESHOOTING
Using a multimeter, first check whether the following voltages are present:
-between b and a: ................... approx. +24 VDC
-between b and P: ................... approx. +24 VDC
(b or M = mass)
Problem
negative tone when pressing the bell push-button
speech & function (e.g. door opener function) are OK, but LED is
not illuminated.
If the external unit needs to be replaced, you can exchange the EEPROMs of the units, so that the programming is retained.
