DAHUA®|ARM320-W2(868)|3 YR WTY. Airshield Wireless Input Expander for mounting inside third party device

The Wireless Input Expander is a conversion device that connects third party detectors to Dahua Wireless Hub. When the alarm of the third party detector is triggered, the Expander sends the signal to the Hub through RF, and then the Hub reports it to platforms. Different alarm types can be configured on the DMSS app, depending on the types of connected detectors. The expander has a triaxial accelerometer in it to prevent the device from movement. An input channel is also provided to connect the tamper port of the third-party detectors. The Expander is powered by dry batteries, and can also provide power supply for
detectors connected to it.
