MOUNTING THE ADD-ON MODULES
A kit (a 10-cm cable with two 8-pin modular jacks) connects the 4081M or 4081L add-on modules to
4012, 4023 and 4034 sets (there is no limit on the number of add-on modules in the system).
Procedure
- Turn the set and the module upside down
- Connect the cable to the set and the module
- Join the module to the set using the 2 screws provided in the kit
The same method is used to connect the 2 modules to each other.
CONNECTING UP AN EXTERNAL BELL
It is possible to connect, on the wall-mounted socket, an external call reinforcing bell to 4011, 4012,
4023 and 4034 sets.
The standard connecting cable is 3 m long and has 2 conductors. To connect an external bell, replace
this cable with an optional cable, 5 m long and with 4 conductors.
Available power: 2 mA under 5V (an adapter is therefore necessary).
