7.4. Connection of Extender Units
The easy installation of the button extender units is one of the great advantages of
using the EntryCom system. The installation could not be easier - the units are
connected using one cable (included in every extender delivery) in a chain manner
(every element in the chain is connected with the preceding one). Every unit has two
connectors – one input (for connection towards the EntryCom basic unit) and one
output (for connection of another, remote unit). For proper function and sequence of the
buttons keep the right orientation of the units and do not interchange these connectors!
