Tax included
A modern and reliable natural gas detector is a key safety element in every home, apartment, or commercial facility equipped with a gas installation. The device is designed for continuous monitoring of methane concentration in the air, which allows for early leak detection and prevention of tragic explosions. Thanks to the use of an advanced microprocessor, the detector is characterized by exceptional operational stability and high sensitivity, which translates into reliability in critical situations.
One of the greatest advantages of this model is its versatility in integration with other systems. The NO relay output allows for the automatic activation of an exhaust fan when gas is detected, which helps in quickly ventilating the room. Additionally, a dedicated control output allows for the connection of a shut-off valve, which will physically close the gas supply to the building, drastically increasing the level of protection.
The device offers dual alarm signaling: a loud acoustic signal with an intensity of 70 dB and clear flashing of a red LED, which ensures that household members will be warned even while sleeping. The self-diagnosis function continuously monitors the technical condition of the sensor, and the TEST/SILENCE button allows for easy checking of the device's efficiency and silencing the alarm if necessary. The aesthetic, compact housing makes the detector discreetly fit into the interior decor, and the included 12V DC power adapter ensures trouble-free system startup right out of the box. By choosing this product, you are investing in the peace of mind and safety of your family, using technology from a renowned manufacturer of security systems.

Specification
Purpose
Detection of natural gas (methane) in enclosed spaces such as kitchens, boiler rooms, or garages.
Detection method
Advanced catalytic sensor with high stability and long service life.
Alarm threshold
10% of the Lower Explosive Limit (LEL).
Acoustic signaling
Built-in piezoelectric transducer generating a sound with an intensity of 70 dB at a distance of 1 meter.
Optical signaling
Multi-colored LEDs informing about power (green), alarm state (red), and potential failure (yellow).
Relay output
NO (normally open) contact used for controlling external devices, e.g., activating an exhaust fan.
Valve control output
Dedicated connector for connecting a solenoid valve to shut off the gas supply in an emergency situation.
Response time
Very short system response time, not exceeding 30 seconds from the moment the threshold concentration is detected.
Control functions
TEST/SILENCE button allowing for manual verification of the device's correct operation and silencing the siren.
Self-diagnosis
Continuous monitoring of sensor and electronic circuit efficiency with automatic error signaling.
Software and logic
The detector's built-in firmware is based on advanced digital signal processing algorithms that analyze the concentration of natural gas (methane) in the environment in real-time. The device's operating system manages the self-diagnosis process, checking the efficiency of the catalytic sensor and internal circuits at every startup and at regular intervals. The software logic has been optimized to minimize false alarms caused by cooking vapors or cigarette smoke, while simultaneously ensuring an instantaneous reaction in case of detecting a real threat at the 10% LEL level. The software also controls the operation of relay outputs, enabling automatic activation of ventilation or cutting off the gas supply via an external solenoid valve. The user interface is implemented through intelligent LED sequences and buzzer sound signals, informing about standby, alarm, or system failure states.
Power parameters
12V DC voltage, 1A rated current. A power adapter is included with the device.
Operating conditions
Wide temperature range from -10°C to 55°C, relative humidity up to 95% (non-condensing).
Housing and mounting
Compact ABS plastic housing, designed for wall mounting. Dimensions: 87 x 87 x 26 mm.
