PRIORITY IN THE INPUTS
The priority function in the inputs reduces the level of the inputs with less priority so that the message
transmitted by the inputs with priority can be heard clearly.
The inputs with maximum priority are TEL. PAGING and SIREN. When there is a signal in the TEL. PAGING
input or the SIREN is activated (by pressing the button on the front panel or closing the SIREN contacts on
the back panel) the level of the rest of the inputs is automatically reduced, INPUT 1 to 4 and AUX 1 and 2.
INPUT 1 is the second level of priority. To enable the priority function through signal level in INPUT 1, the
INPUT 1 PRIORITY contact on the back panel must be closed. In this way when a signal is detected in INPUT 1,
the rest of the inputs, INPUT 2 to 4 and AUX 1 and 2, will be weakened.
The last priority level is in the CHIME signal and INPUTs 2 to 4. This priority is activated by closing the CHIME
PRIORITY contacts on the back panel and weakens the AUX 1 and 2 inputs.
