Product information

Description

The Dahua Technology ARA12-W2(868) White ABS PC is an alarm detector accessory engineered for integration with compatible security systems. It operates on the 868–868.6 MHz band and is powered by a single CR123A battery. The enclosure is manufactured from ABS and polycarbonate (PC), providing impact resistance and stable performance in typical indoor environments. Its compact footprint supports flexible placement in residential or commercial installations.

Advantages

The device supports frequency hopping and two-way communication technology to maintain reliable radio links and reduce interference. Built-in signal strength detection helps installers verify placement and connection quality. A low battery alarm notifies the system when battery replacement is required, and integrated temperature measurement provides additional environmental data for the security system. Cloud update capability and automatic recovery from update failure ensure the accessory can receive firmware improvements with minimal manual intervention.

  • Wireless alarm systems requiring 868 MHz accessories
  • Residential security installations
  • Small commercial premises and offices
  • Locations needing remote firmware updates and diagnostics

How to use

Install the ARA12-W2(868) in accordance with the host system’s installation guide, placing the unit where signal strength is sufficient and environmental temperature measurement is relevant. Insert a compatible CR123A battery following polarity markings, then follow the security panel or gateway procedure to enroll the accessory. After enrollment, verify signal strength and functionality using the host interface; check that low battery and temperature readings are reported correctly. Keep the enclosure closed and mounted to prevent moisture ingress and mechanical damage.
