Outdoor Wireless Siren DAHUA DHI-ARA13-W2(868) orange — 868.6 MHz, 12 V, CR123A battery, ABS/PC housing, 200×200×52.5 mm

Dahua DHI-ARA13-W2(868) orange is an outdoor wireless siren designed for perimeter and building exterior alarm signaling. The unit features an ABS/PC weather-resistant housing and compact dimensions (200×200×52.5 mm). It communicates at 868.6 MHz with frequency hopping and two-way communication, and can be powered from a 12 VDC supply or by CR123A alkaline batteries. The siren provides audible and visual alerts with selectable alarm tones for intrusion, fire, medical, panic and other events, and includes temperature monitoring and remote update capabilities.

Advantages

The siren’s IP65-rated ABS and polycarbonate enclosure offers protection against dust and water, making it suitable for outdoor installation across a wide temperature range (–25 °C to +60 °C). With a sound pressure level of 110 dB and multiple alarm sound types, it delivers clear audible warnings while the bright orange housing improves visual recognition. Two-way wireless communication and frequency hopping increase link reliability, and cloud firmware update with automatic recovery reduces maintenance effort.

Suitable for

• Perimeter protection for residential and commercial properties
• Exterior mounting on houses, garages or outbuildings
• Integration with wireless intrusion and alarm systems
• Sites requiring visual and audible deterrence (construction sites, warehouses)

How to use

Mount the siren on a vertical surface using suitable fasteners, ensuring the housing faces outward and the chosen location provides good wireless reception to the alarm panel. Connect to a 12 VDC supply where continuous power is required, or install CR123A batteries for backup or standalone operation. Pair the device with a compatible wireless alarm system on the 868.6 MHz band following the system’s enrollment procedure. Configure audible tone types and cloud update settings through the control panel or associated management platform. Observe IP65 installation practices to maintain weather resistance, and ensure temperature monitoring is enabled if required by the system.

Usage recommendations

For reliable long-term operation, install the siren at a height and orientation that avoid direct water pooling and reduce accidental tampering. Use a stable 12 VDC supply for primary power in permanent installations and regularly check CR123A battery health if batteries are used. Schedule remote firmware updates during low-activity periods and verify automatic recovery after updates to maintain firmware integrity.
