GK Combined CH4&CO Alarm
The GK Combined CH4&CO Alarm is a two‑in‑one detector designed for both residential and small‑office settings, capable of sensing methane and carbon monoxide simultaneously. It accepts an AC220V±15% or AC110V±15% supply at 50‑60 Hz and incorporates a DC12 V backup to maintain operation during power outages. Sensor longevity exceeds three years, with methane alarm activation set at 10 % LEL and carbon monoxide response adhering to EN50291. The unit operates safely between - 10 °C and 50 °C, though specific humidity limits are not listed.
Typical models in this category feature an IP44‑rated housing, a 9 V alkaline battery for standby, and an audible alarm output of 85 dB at 3 m. Manufacturers often provide optional valve and relay outputs to allow integration with building management or fire‑alarm systems. Response times are usually under thirty seconds, and compliance with IEC 61065 is common for safety assurance. These industry norms give buyers a benchmark when evaluating the supplier’s offering.
The alarm is aimed at homeowners, landlords, and contractors who need a compact safety solution that saves wall space. Bulk purchases are possible for developers fitting multiple units into new constructions, and the supplier can accommodate custom packaging upon request. Prospective buyers should confirm the exact lead time, Incoterms and payment schedule, as these details are not disclosed in the product listing.

Sourcing GK Combined CH4&CO Alarm from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Importers should first obtain the product’s certification copies, battery specifications and any available test reports to confirm that the alarm meets local safety regulations. Requesting a functional sample can also help verify the optional valve and relay outputs before placing a larger order.
Shipping from Zhengzhou typically uses FOB terms at the nearest port, with air freight available for urgent deliveries. Because the supplier’s lead time and payment conditions are not published, these must be negotiated and documented in the contract. Common payment methods include T/T and L/C, but the preferred arrangement should be clarified early in the dialogue.
A thorough pre‑shipment inspection should cover visual quality, functional alarm testing and verification of the supplied certification documents. Engaging a local third‑party inspection agency can provide an independent assessment. Retaining all inspection reports, warranty certificates and compliance paperwork will facilitate customs clearance and future after‑sales support.
