MD368 Series UART Smoke Alarm

Our new MD368 series detector is designed to meet the needs of manufactures of smart home, IoT applications. Not only the detector offers aesthetically appealing professional design and seamless operation, it also comes with extra room to fit a Sub-1Hz RF module, ZWAVE, ZIGBEE and WiFi module with two way communication though UART interface. The model with extension B1 is used a CR123A lithium battery power to both detector and RF module; the model with extension B3 is equipped with two sets battery, two L91 AA size PCB mounted lithium batteries (its life time up to 10 years) supply power to detector itself and an additional replaceable CR123A lithium battery supply power to RF module. Professional installers will be able to remove the smoke chamber to ease cleaning and save on maintenance time.

Approvals 
 UL217 / 268 / 521 standards ; EN54-5 standards ; EN14604 standards
