All sensors and accessory components supplied with your CarPro-Tec are already taught-in and fully configured. 

Please use the CarPro-Tec quick guide for the initial commissioning of your new CarPro-Tec. Thes detailed instructions will help you with detailed setting options.

General information

Our TriGasPro multi-gas detector reliably monitors the interior for the formation of dangerous gases before they reach a potentially life-threatening concentration in the breathing air.

The TriGasPro detects cooking gases (butane, propane), which are commonly used in the camping sector, as well as so-called KO anaesthetic gases.

Single or with CarPro-Tec

Like any conventional stand-alone gas alarm, the TriGasPro can also be used without CarPro-Tec, as it triggers its own alarm in the event of danger.

In combination with CarPro-Tec, safety is enhanced by the additional triggering of the alarm system and the immediate alert on your smartphone.

In addition, the alarm of the TriGasPro multi-gas alarm does not stop until the ambient air is safe again.

The TriGasPro is supplied with power via the USB-C connection cable included in the scope of delivery from an available USB port or the supplied power supply unit. In addition, the TriGasPro multi-gas detector has a small emergency battery that provides backup power for up to 4 hours in the event of a power failure.


The TriGasPro detects the following gases and hazardous vapours:

  • Propane
  • Butane
  • anaesthetic gas
  • Natural gas
  • Town gas
  • Methane
  • Nitro thinner
  • Petrol
  • Ether
  • Alcohol
  • Adhesive vapours



Please note: All sensors and accessory components supplied with your CarPro-Tec are already taught-in and fully configured. 


To commission the TriGasPro for the first time, follow the instructions below under "Initial commissioning and function test". 

1. First supply the TriGasPro with power using the USB cable supplied (Fig. 7)

2. Switch on the TriGasPro using the switch on the side (Fig. 9). You will find additional information on this under point 3 of the initial commissioning.

3. Press and hold the ACCESSORIES button on the CarPro-Tec with a thin object. (ACCESSORIES LED in the status LED bar lights up red)

4. Release the TriGasPro as described in steps 4 and 5 of the initial commissioning procedure

5. The CarPro-Tec beeps twice if the teach-in process was successful.

6. Release the ACCESSORIES button

Teaching out

To decouple a TriGasPro that has already been taught-in, repeat steps 1-4. The CarPro-Tec beeps once and the red LED goes out after the teach-in process has been successfully completed.

Installation example

Installation instructions

We recommend installing the TriGasPro at a height of at least 10 cm to a maximum of 30 cm, as gases such as propane, butane and anaesthetic gas are heavier than air and therefore first collect on the floor before spreading further into the room. It should also always be installed close to the sleeping area.

This installation position ensures that the gas can be recognised and detected at the earliest possible time.

Mounting the TriGasPro below a height of 10 cm is not recommended, as draughts and escaping heating air are more likely to occur here.

We recommend screw-free installation using the 3M magnetic pads supplied. Please observe the installation instructions for

 3M adhesive pads.

Initial commissioning and function test


  1. First supply the TriGasPro with power using the USB cable supplied (TriGasPro remains switched off).
  2. Then wait 3 minutes so that the TriGasPro gas detector can calibrate itself with the ambient air.
  3. Now switch on the TriGasPro. If no continuous beep sounds (>10s) and the LED lights up green continuously, the sensor is ready for use.
    (Note: If the TriGasPro beeps continuously (>10s), subsequent calibration to your ambient air is necessary. Please see the "Calibrating the sensor" section below)
  4. Now carry out a function test using a commercially available lighter by letting gas flow out of the underside of the TriGasPro without a flame. This should now trigger within a few seconds despite the small amount of gas (continuous beep, red LED). The sensor stops the alarm (continuous beep) when the ambient air is defined as safe again. You can speed up this process by blowing vigorously on the sensor with breathable air.
  5. The TriGasPro now lights up permanently green, no longer emits a continuous beep and is therefore in monitoring mode.

Optional calibration of the sensor

If the TriGasPro beeps for longer than 10 seconds during initial commissioning, please reduce the sensitivity of the TriGasPro sensor. Use a small Phillips screwdriver to do this.

  1. Gently turn the potentiometer on the back of the device (small hole) clockwise in a minimal turning motion until the beeping stops (see illustration below).
  2. The sensor is now calibrated to your ambient conditions.
  3. Finally, carry out steps 4 and 5 of the initial setup.



more sensitive = turn anti-clockwise 

less sensitive = turn clockwise


For your own safety, your TriGasPro should be checked/maintained regularly.


Visual inspection of the TriGasPro status LED. This must light up green continuously.


Visually check that the openings are freely accessible and that the TriGasPro is not damaged. Carry out a function test with a commercially available lighter as described under point 4 of the initial commissioning.
