Wiring
Placement
The sensor must be placed 150-180 cm from ground level on a side wall or on a vertical surface at inhalation height. One sensor can cover an area of around 25-50 m2, but the design of the room and the areas where the gas can stop must be taken into account.
Cabling
Depending on the distance between the SENS-EX TG/A-E-CONO2-A-GS sensor and the control panel, use a 4-core, 0.75-1.5 mm2, twisted-pair, shielded circular cable with a maximum resistance of 25 Ohm/1000 m. Use a stranded cable between the control panel and the sensor, connecting all sensors in the system in series.
