The Dahua DHI-ARM320-W2 Wireless Input Expander is a versatile device designed to integrate third-party detectors into Dahua’s wireless security systems. It supports six types of alarms: intrusion, medical, fire, emergency, gas, and tamper. With a two-way wireless encrypted communication mechanism and frequency hopping technology, it ensures stable and secure communication even in environments with wireless interference. The device operates on three CR123A batteries, providing a long battery life of up to 5 years. It also features a triaxial accelerometer to detect unauthorized movement, triggering alarms accordingly. The expander can be powered by external supplies and sends alarm signals through RF to the hub, which then relays them to platforms like the DMSS app. The device is also cloud-updateable, making it easy to keep firmware up to date. Key Features Six types of alarms: Intrusion, medical, fire, emergency, gas, and tamper. Connects to external power supplies. Triggers alarms when the device is moved. Alarms go off 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 hops to other available frequency bands when the original frequency band is being interfered with by other wireless radios, ensuring smooth communication.
