26 E3M140 Line module ”FD20”
26.1 Overview
z Line module for addressable Sinteso
TM
devices
z I-Bus module with line processor and P2-LineDriver
z Designed for 2 loop lines or 2 stub lines
z Line inputs protected against over voltage
z integrated ground fault monitoring
z Lines are galvanically isolated from the control unit
z Card format 100 mm x 200 mm
z I-Bus address is set at programming switch ”I-BUS ADR”
z Synchronization of the alarm devices in the FDnet
26.2 Key data

1) Depending on type of cable –> see document 001508 and 008478
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
– for direct connection of the periphery
Card chassis
– mounted on module chassis
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.
