The STRAJ S51A3K is a specialized gas detector designed to monitor levels of methane and carbon monoxide, ensuring safety in environments where these gases might accumulate. Equipped with an ACHE-16 sensor, it triggers an alarm when methane reaches 0.5% or carbon monoxide hits 0.01%, while also monitoring for temperature spikes up to +55°C. Once the initial 30-minute warm-up period is complete, the device responds quickly, detecting methane in under 30 seconds and carbon monoxide within a minute, alerting you with a sound level of at least 85 dB. This compact unit is housed in a shock-resistant plastic case measuring 120 x 85 x 55 mm and weighing 250 g, making it easy to install in various locations. It operates on a standard 110V-220V power supply and is built to last with a service life of at least 10 years, provided it undergoes annual verification. To help you manage emergencies, the detector includes external outputs that can be connected to a 220V electromagnetic shut-off valve or an exhaust fan to automatically mitigate risks. Designed for reliability, the device functions in temperatures from -10 to +40°C and humidity up to 90%, conforming to the DSTU EN 50194 standard. You can easily check the system status via the power, fault, and gas indicators, or use the dedicated test button to ensure everything is working correctly. Its IP22D protection class and Class II electrical insulation make it a dependable choice for those needing constant, automated monitoring of hazardous gases.
