6.5.1 Inputs
The input signals or passage clearance (HAB1 and HAB2) or anti-panic (BQC) can be
originated by a relay contact, pushbutton contact, tension from 5 to 24 Vca/cc, from
110 to 220 Vca/cc. To enable passage through relay contact or pushbutton, make the
connection as shown below:
Enabling passage through tension pulse is shown in the image below. It is necessary
to observe the polarity of the CC voltages and to use an external resistor for high
voltages (110V and 220Vca).
