CP.BISON OTI CONTROL UNIT
INPUT/OUTPUT FUNCTIONS
CAUTION!: The CP.BISON OTI control unit is equipped with an embedded anti-crash device (amperometric 
sensor). Given the overall dimensions of the door leaves for which the device is intended, the latter cannot 
be considered a safety device. It is therefore STRICTRLY MANDATORY to install activated protection sen-
sitive edges according to regulations in force.
