F918 Series UART Gas Alarm

Our new F918 gas alarm is designed to meet the needs of manufactures of smart home, IoT application. Not only the detector offers aesthetically appealing professional design and seamless operation, it also comes with extra room to fit a Sub-1GHz, ZWAVE, ZIGBEE and WiFi module with two way communication through UART interface. The power supply from an USB connecting switching power adaptor, the model number with an extension B is used a CR123A  for a backup power for transferring the power failure signal only through UART to wireless system. The model with extension S is designed for 4-wire connection system. The model with extension R is designed for dry-contact output.

Approvals 
 Comply with UL2075 standards ; EN50194 standards
