2. OPERATION
GUARD UNIT - HOUSE
The GUARD UNIT-HOUSE status (green LED lit) is the state in which the Central
will initialise every time the key is used to connect. In addition, the Central returns to this
state automatically when, upon entering any other state, it detects that the conversation
is over or there is no activity. In this state, the conversations are established between
the Central and one of the apartments or else between any two houses. The status
LED blinks during the conversation until hanging up is detected.
HOUSE - HOUSE
If one apartment wishes to talk to another, they call up the Guard Unit Central
and give the concierge the number of the house they want to call. The concierge makes
the call to the other dwelling and waits for them to answer. Once communication is
established between both houses, the concierge hangs up and the green LED blinks for
the duration of the conversation.
The concierge may intervene in the conversation between two houses at any
time.
HOUSE - PANEL
In this state, the Central allows direct communication between the house and the
outdoor panel. The yellow LED keeps blinking during the conversation and when the
house phone is hung up, the Central detects it and automatically goes into GUARD
UNIT-HOUSE mode (green LED lit).
