2) Max. distance from control unit to the element furthest away is 2500 m
Terminal block X17 (20 terminals)
–
mounted on module chassis
–
for the connection of the prefabricated cable to connection level, or
–

26.3 Special
functions
Emergency operation
–
Alarm evaluation upon ”Emergency operation” via
line processor
–
Upon emergency alarm, control console B3Q... gives a ”combined alarm”
with
flashing response indicator at the detector
–
Upon line short circuit
and
failure of the line processor there is
no
”Emergency
alarm”
–
Mimic display output (connector SYNOPTIK) only active with emergency alarm
Line separator
Upon short circuit the part of the line which malfunctions must be separated from
the rest of the line. This is carried out by line separators integrated in the devices.
