Safety instructions
The device may only be used within the specifi ed
ambient and working temperature range. Utilisa-
tion in ranges other than those specifi ed or the
modifi cation of the product by anyone other than
the manufacturer is not permitted and will exempt
BARTEC from liability for defects and from any
further liability. Incorrect installation may cause
malfunctioning. The generally applicable statutory
rules and other binding directives relating to work-
place safety, accident protection and environmen-
tal protection must be observed. The applicable
laws and directives must be complied with before
commissioning or restarting the device. The device
may be operated only if it is in a clean and undam-
aged condition. Conversions and modifi cations are
not permitted.

Water leakage detection system
The SCR sensor cable (illustration with connections
assembled by the customer) is a component in the
BARTEC water leakage detection system. It works
in connection with the RDA 01, RDW 03, RLA
net
or
RLW monitoring electronics. Other components in
the BARTEC water leakage detection system are
the PS point sensor, zone divider module, T branch,
plug set, socket set, and accessories (see Cata-
logue).
Description
The system detects even small liquid leaks quickly
and reliably. Optical and acoustic alarms are emit-
ted from the RDA 01, RDW 03, RLA
net
or RLW
monitoring electronics. At the same time, fl oating
contacts are set for signals to the building services
management and control tasks. The SCR sensor
cable has two NiCr sensor wires with PTFE partially
perforated insulation and two fully insulated return
conductors along its entire length. The high-quality
outer FEP plastic braiding off ers ideal mechanical
protection. In the event of contact with a conducti-
ve fl uid (e.g. water) the electric contact resistance
between the two sensor wires is reduced. This
change is measured, detected and signalised by
BARTEC´s RDA 01, RDW 03, RLA
net
or RLW mo-
nitoring electronics. The defi ned resistance in the
SCR sensor cable of approx. 6 Ω/m in connection
with the RLA
net
or RLW monitoring electronics al-
lows a precise location of the leak. The location of
the leakage is shown in metres on a large display
and it can be transmitted to the building services
management through diff erent interfaces.
