I installed a Fermax City Max entry System with 3 handsets.
As I do not need the door lock release I wired up only 4 wires. #2,3,4,6.
All 3 handsets are wired into the door buzzer module.
When I power up I can here a cycling 'dut dut dut' noise coming from the door buzzer.
When I press the buzzer all the handsets ring.
But I cannot hear nor be heard via the system on any of the handsets.
All the wiring seems to be correct.
Any ideas where I should be checking?
