8.5.6. Input connections
AA-560 has six inputs for acquisition of external contacts (3 of each: 4, 5, and 6 optoisolated) useful to indicate
special conditions or alarm. Upon detection of activation of the contact connected to each input, it can be
associated with a different phone number to contact (to which the operator that must handle the event must
answer).
Usually the inputs of the system are connected to normally open contacts that its closing will active the call
sequence signaling. It’s possible to program the system to reverse this way of detection, so that the acquisition of
activation of the contact and the triggering of the respective signaling takes place after the opening of a contact that
is closed under normal conditions.
AA-560 continuously monitors the status of its three inputs (and the respective external contacts connected).
In case of activation conditions, AA-560 stores it in non-volatile memory and is responsible for triggering the cycle
of notifications. In case of AA-560 power off, when the power come back the system alerts will be resumed.
The connector TB5 contacts also has the terminals for connecting an additional external speaker.
