AVANSA 100M gas detector

Product detailed description

The AVANSA 100M gas detector is commonly used in residential and commercial buildings where gas appliances such as boilers, cookers, and water heaters are installed. Installers typically fit these detectors in kitchens, utility rooms, boiler houses, and industrial gas storage areas. The device is suitable for both indoor and outdoor environments within specified temperature ranges. It is often integrated into larger safety systems that include gas valves, control panels and monitoring equipment. The detector ensures early warning of gas accumulation, allowing for prompt action before potential hazards arise.

Its design allows for reliable operation in a wide range of conditions, making it ideal for both new builds and retrofit projects. The device is particularly useful in systems where gas is stored or used intermittently, such as in seasonal heating applications or in facilities with multiple gas points of use. Its low power consumption and compatibility with solenoid valves make it a practical choice for both small-scale and large-scale installations.

Technical parameters

Installation and connection

Mounting should be performed in accordance with local gas safety regulations and the manufacturer's guidelines. The detector should be placed at a height that corresponds to the density of the gas being monitored—methane rises, while LPG tends to settle. Fixing is typically done using screws or wall brackets provided with the unit. The power supply is standard 220V AC at 50Hz, requiring a dedicated circuit or fused spur.

For integration with a solenoid valve, a 12V DC power source is required. The polarity of the wiring is critical: white wire is positive, black wire is negative. Connectors should be secured and insulated to prevent short circuits. A common mistake during installation is incorrect orientation—detectors must be mounted horizontally. Another frequent error is placing the unit too close to heat sources or ventilation ducts, which can affect sensor accuracy.

Compatibility and accessories

The AVANSA 100M is compatible with solenoid valves rated for 12V DC. For full system functionality, a solenoid valve must be installed separately and connected via the designated terminals. The detector does not include a power supply unit, so a suitable fuse or circuit breaker must be installed upstream. Additional accessories such as mounting brackets, cable glands and junction boxes may also be required depending on the installation location and method.

Technical background for designers

The AVANSA 100M employs a catalytic sensor that reacts to combustible gases. When gas molecules come into contact with the sensor surface, a chemical reaction occurs, generating a measurable change in resistance. This change is processed by the internal electronics and triggers an alarm if the threshold is exceeded. The sensor is housed in a durable plastic casing that resists corrosion and mechanical damage.

Material selection ensures long-term stability and resistance to environmental factors such as humidity and temperature fluctuations. The operating range of -15°C to 50°C and humidity tolerance of up to 97% RH make it suitable for a broad range of climates. Integration into a system requires careful planning of signal paths and power distribution. The device’s low power consumption makes it suitable for use in energy-efficient designs.

Service and operation

Regular inspection of the detector is recommended to ensure continued performance. This includes checking the integrity of the housing, the tightness of electrical connections and the clarity of the alarm sound. No scheduled service intervals are specified, but functional testing should be carried out periodically. In the event of a false alarm, the cause should be investigated—possible issues include dust accumulation or interference from non-target gases.

When the detector activates, it is important to verify the presence of gas and isolate the source before resetting the unit. The alarm remains active until the gas concentration drops below the threshold level. If the system is connected to a solenoid valve, the valve should be checked for proper operation after any alarm event.

Frequently asked questions

Can the AVANSA 100M be connected to a solenoid valve?
Yes, the detector supports connection to a solenoid valve operating at 12V DC. Ensure correct polarity when making the connection.

Is the AVANSA 100M suitable for outdoor installation?
It can be used outdoors as long as it is protected from direct weather exposure. The operating temperature range allows for use in most outdoor conditions.

How long does it take for the alarm to activate after gas is detected?
The response time is less than 30 seconds. This allows for quick reaction in case of a leak.

What is the maximum noise level of the alarm?
The alarm produces more than 90 dB at a distance of 1m. This ensures it is clearly audible in most environments.
