ALARM INPUT

Possibly connect a sensor to the auxiliary input IN1. The input is referred to ground (-) and can be programmed
as NC, NO, Single balancing and Double balancing. The input can also manage fast signals coming from seismic
sensors or rolling shutters; in this case, the connecting mode is fixed on NC. In order to connect with balancing
use the provided 2.7kohm resistors with 1% tolerance.
WARNING! "Double balance" is the only EN50131 compliant connection mode. Refer to the manuals of
1068 series control units for further, more detailed information.
