Questions about Wireless gas alarm

Both the bottled gases (propane/butane) used in the leisure sector and the substances used in narcotic gas attacks are heavier in gaseous form than air, meaning that they initially collect at the bottom of the vehicle.
A corresponding gas sensor should therefore always be mounted below the sleeping areas in/on a vertical surface. About 10–30 cm above the floor is the right height. In this way, you will have enough time to react in an emergency.
If the space is divided by curtains or sliding doors, a further gas sensor or standalone gas alarm makes sense.
Please ensure a sufficient distance from the sensor to heating outlets and gassing batteries in each case.

In contrast, CO sensors are preferably mounted as high as possible. Close to the ceiling is optimal.

Our gas sensors detect propane, butane and the entire range of anaesthetic agents / narcotic gases. Accordingly equipped, G.A.S.-pro and G.A.S.-pro III also detect carbon monoxide.

Gas warning systems are often said to be prone to false alarms.
Above a certain concentration, gas sensors also react to substances similar to anaesthetic gases. Technically speaking, these are not false alarms; the gas alarm is triggered by, for example, deodorant sprays, aftershave, strong cleaning agents, body odours (particularly from pets) or even breath alcohol.

Despite temperature compensation, continuous self-tests and intelligent software analysis of the sensor’s readings, false alarms cannot be completely ruled out. However, by ensuring the correct installation height, unwanted alarms triggered by the substances mentioned above can be significantly minimised.

In an attack or break-in attempt with narcotic gases, chemicals from wholesalers are frequently used. Chloroform or aether are known, but substances, e.g., from the production of plastics are also used. They cost very little in large containers there and are rarely subject to identification.

The liquid chemical passes via an injection cannula through rubber seals or mechanical ventilation vents into the interior and evaporates there at room temperature to form a gas mixture. This fills the vehicle from the bottom up and puts people staying there overnight in a half-asleep state.
This half-asleep state allows intruders to apply a much higher level of noise and still remain undetected.

The third wire in the connection cable for the compact gas alarm is only used in a special customer version (OEM) and can be shortened/ignored for normal operation.

Please, not with a propane gas bottle! And methylated spirits or similar are also not suitable, but can even damage the sensor head. A test can be safely carried out with a commercially available lighter and should even be carried out regularly. Simply blow out the flame on a lighter with electronic ignition.

Yes. It is ‘only’ the supply cable for the power supply. Please use cables of the same (3x0.14²) or larger cross section and ensure a reliable connection.
