Dahua ARM320-W2(868), Wireless module for wired zone with AirShield

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

• Six types of alarms: burglary, medical, fire, emergency, gas and sabotage.
• Connects to external power supplies.
• Activates alarms when the device is moved.
• Alarms will sound when the device overheats.
• Cloud update.
• The two-way wireless encrypted communication mechanism improves the security and stability of communication.
• With the wireless frequency hopping mechanism, the device automatically switches to other available frequency bands when the original frequency band is interfered with by other wireless signals, to ensure smooth communication.
