G.A.S.

Both gas warning systems detect propane, butane and KO / anaesthetic gases and must be connected to the vehicle's power supply.

To do this, the device is screwed into a suitable location inside the vehicle. Please note that both devices must be mounted as low as possible in the vehicle, as the detected gases (propane, butane and KO / anaesthetic gases) are heavier than air (for more information, see the FAQ Where should a gas sensor be mounted?).

G.A.S. is a stand-alone gas warning system with its own siren (inside the device) for installation in your vehicle.

G.A.S.-connect, on the other hand, is integrated into the WiPro III (safe.lock) alarm system. To do this, the gas warning system is interconnected with the alarm system via radio connection. G.A.S.-connect does not have an own siren (inside the device), but warns via the internal siren of the alarm system as well as the horn and hazard warning lights of the vehicle instead.

This alarm output allows you to connect a backup siren to your device. A backup siren is particularly recommended for large vehicles or heavily insulated motor compartments, where a backup siren with a volume of approx. 105 dB can ensure that no alarm goes unheard.

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 alarms are often said to be prone to false alarms.
Gas sensors also respond to cylinder gas- or narcotic gas-like substances in certain concentrations. Therefore, technically speaking, there are no false alarms; it is just that possible causes are not linked to the device:
deodorants, aftershave, harsh cleaning agents, bodily gases (especially from our four-legged friends) or even alcohol on the breath or fondues can by all means cause a sensitive gas alarm to go off.

Despite the temperature compensation, the continuous self-tests and the intelligent software evaluation of the sensor measurements, sometimes a false alarm cannot be ruled out.
The reliability in an emergency comes first:
It’s better to have an alarm go off one too many times than one too few.

Just the right mounting height simply filters out only ‘bad’ gases (i.e. false alarms) decisively.

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.
