CONNECTION WITH GAS DETECTORS (Sensors)
Please always refer to the specific instructions supplied with detectors
Please note that the Control Unit has relay output no.5 outputs. An ES414 board can be
installed to have a total of 9 outputs. In the diagrams, for simplicity, they are always indicated
with all the Outputs.
Cable section and distance between Control Unit and Sensors: They must be 3-pole shielded
cables, with a section suitable for the distance as indicated below in the table.
Distanza massima di ogni rilevatore dalla centrale
Maximum distance of each detector from the control panel.
Distance maximale de chaque détecteur du panneau de contrôle
Max. 200 metri / meters / mètres
Max. 400 metri / meters / mètres
Max. 600 metri / meters / mètres
Connection of the detectors: (Sensors 1÷8) is carried out on the Input boards (4 ÷ 20mA) mounted
in the base on the left, the terminals "+", "-" and "S" must be connected to the corresponding terminals
of the detector.

ES404 - Expansion board with inputs 5÷8
Fig 6 – CE424P - Wiring diagram for Inputs Sensor 4 to 20mA and relay Outputs
Connection of the other detectors: (Sensors 9÷24) is carried out in the Remote Units (See specific
instructions).
The cable shield must be connected only from the Control Unit side and on a single "EARTH" point
which must be equipotential. On each detector (sensor) it will be necessary to use two cable glands,
one for the input and one for the output.
