The sensor should be
located in the room at
least 3.5 m from the
floor.
Avoid locating the sensor near the access door.
9.3. DIMENSIONS
9.4. ASSEMBLY
Sensors can be fixed with 2 screws.
·ceiling or wall position
·detection zone = zone situated 1 metre from the partitions (the so-called "dead" zone, where there is little movement)
·installation height in ceiling position: between 2.5m and 3.5m.
9.5. ELECTRICAL CONNECTION
·power supply and transfer of information via VMX specific bus
·the sensor is connected to the system by just 3 wires with a section of 1.5 or 2.5mm²

9.2. DESCRIPTION
CO
2
sensors enable the measurement of concentrations of CO
2
in a room.
The principle of the analysis consists of measuring the absorption of infra-
red rays so as to establish concentration in the room. This method gives a
very accurate response and it is independent of all other types of pollution
(such as humidity, dust accumulation, etc.). In the "full or little" operating
mode the CO
2
threshold can be regulated via a button on the sensor box
(from 700 ppm to 1,700 ppm per 200 ppm steps).
