The gas explosion accident happened in Shiyan Hubei on June 13 was heart wrenching, meanwhile sounding the alarm for all of us on gas safety. On the next day of the tragedy, the State Council Safety Committee Office and the Emergency Management Ministry held video meeting to supervise the event handling and redeploy the current national gas safety precautions.

In association with ministry of Housing and Urban-Rural Development, Emergency Management Ministry promoted the fair trade markets, catering places to install gas leakage alarm devices, practically solving gas security problems and preventing from such accidents.

Goldcard’s 5G NB-IoT natural gas alarm received extensive attention. With over 20 years engagement in the gas industry, and continuous exploration and practice on the gas safety technology, we developed the wireless gas alarm, suitable for various sceneries including home, catering, malls, hotels, schools office buildings, etc.

When natural gas concentration achieves alarm threshold, the sound and light alerting signals will be triggered, the alarm will be sent to linkage equipment, inform the gas companies, the community offices and the end users simultaneously.

Plug and play is one of the NB-IoT natural gas alarm’s biggest attractive points, it can work independently without gateway, and it supports remote alarm, concentration reporting, remote silencer, device expiration reminder etc. By virtue of the alarm, users can see the gas security situation at home in time and predict potential leakage risk ahead of time.

Main Advantages

● Dedicated IoT network, in-time and reliable service
A built-in NB-IoT card, automatic connection to network. Alarm messages with gas concentration value and danger level can be timely received on SMS, Wechat official accounts and mini programs, users can turn off the alarm remotely on Wechat APP. Moreover, alarms can be sent simultaneously to up to ten family member or related personnel.

● High sensitivity and low false alarm.
The gas sensor is able to detect gas leakage in ultra-low concentration (250ppm). In combination with the full-range temperature compensation and false report prevention system, increases anti-interference ability and reduce false alarms.

● Dust-proof and water-repellent design to extend service life
Multi-layer labyrinth air intake design avoids water vapor condensation entering into the device. The sensor is positioned at the back effectively reduces the direct sweep of oil smoke. The entire structure achieves IP 51 protection level.

● Lockdown potential risks, guarantee gas security
Continuously and automatically collecting gas concentration data in the environment， and storing hourly maximum value. Users inquire history data and alarms through Wechat APP, to discover and predict potential leakage risks, handle in time and prevent accidents.

● Configurable sensitivity, reassuring and free from worry
The detecting sensitivity can be adjusted in accordance with real gas environment,

● Intelligent linkage, avoid bigger losses
When natural gas leakage was detected and alarm was triggered, the linked IoT gas meter will shut off valve automatically, the smart exhaust fan will be turned on to reduce possible risks.

Goldcard has coordinated with gas companies, promoting smart and safe kitchen construction in communities and villages, so that enable the solutions real safe guards for residents.
