Furthermore, the correct electrical connections according to the enclosed drawings, complying with
instructions and Regulations in force, and the use of the safety fuse, are recommended.
Indeed, the most essential factor for the proper functioning of the GS911K is its correct installation.
By following the instructions in this paragraph high precision can be obtained together with the
absence of false alarms.
Once the device has been turned on, the MAINS LED lights up, and the GS911K is ready for detection
after 60 seconds.
Press the button near the detection capsule to simulate the presence of gas.
The ALARM LED lights up, and the relay shifts its functioning mode after one second.
After the alarm, the LED will turn off, the buzzer will stop, and the connected appliances will be turned
off.
To complete the general test, issue gas from a pre-calibrated aerosol within 20% of L.E.L. Testing
using a common cigarette lighter could damage the sensor.
Installation measures and positioning
The position of the detector is a crucial factor for its correct functioning during gas detection.
In order to obtain the maximum results from a device and minimize the probability of false alarms,
it is recommended to follow this scheme and keep in mind the following general regulations.
The detector must be located at different heights, according to the type of gas. These heights are:
- 30 cm from the lowest point of the floor in order to detect
heavy gases, LPG, etc.
- 30 cm from the highest point of the ceiling in order to detect
light gases, Methane
- The detector should not be placed near the appliances to be controlled (boilers, burners, industrial
kitchens, etc.) but on the opposite wall.
- The detector should not be affected by smoke, vapour, etc. as they could distort its measurement.
It should be located away from sources of heat, ventilators or fans.
