Recommendations - Duran Electronica 203 PLUS Serie Manual De Instalacion Y Uso

13. RECOMMENDATIONS

1.- Do not connect the detectors to their bases until the whole building work has been
carried out and remember that once installed, power should be provided as soon as
possible.
2.- To carry out the installation, use an individual duct and avoid installing the detector
close to sources that generate electromagnetic disturbances (fluorescent lights, engines,
counters, etc.) It you cannot avoid installing them close to these disturbances, we
recommend you use shielded cable (hose)
3.- Do not use the detector base as a register box to make service connections to more than
one detector, use the terminals supplied for the cabling of the detector base.
4.- Do not drill holes in the control unit cabinet, as the metallic shavings could irreversibly
damage the electronics.
5.- In compliance with the STANDARD EN 6.1010-1, 1.5 mm
be used for the 230 AC connection to the control unit, protecting the input with a 5A
contactor or circuit breaker and installing it as close as possible to the control unit.
6.- When designing the installation, try to avoid long stretches of cables to avoid voltage
drops and whenever possible, close the line loop (join the first detector to the last one). If
in spite of all this, there are drops in voltage, you will have to install supplementary power
supplies at the end of the lines (consult your supplier).
7.- Do not manipulate the module lines or the detectors without previously disconnecting
the line.
8.- Remember that the minimum voltage needed for a detector to be able to function is
8V and check the voltage of the last detector on the line.
9.- When the installation is 2.5 years old the activated carbon filter should be replaced.
After 5 years replacement of the sensor and calibration should be carried out at our
laboratory or another authorised by DURAN ELECTRONICA.
10.- REMEMBER that the detectors should not be left in the installation when:
• The control unit or the lines are disconnected
• There is no voltage or when there is only temporary power supply for the
building work
