Overview
The Dahua ARA43-W2 is a wireless alarm repeater. It sits between a Dahua wireless alarm hub and detectors that are too far away or behind thick walls and floors, picks up their 433 MHz radio signals and passes them on to the hub. It suits a large house, a multi-storey shop, a warehouse or a campus building where part of the alarm is out of the hub’s reach.
Is it right for you?
- It suits a Dahua 433 MHz W2 series wireless alarm where some detectors have a weak signal to the hub.
- Each ARC3000H hub takes up to 4 repeaters, so plan placement around that limit.
- It is for indoor use, -10 to 55 °C, mounted on a wall or placed on a desk.
- Real range depends on the building, so it is for extending coverage, not a substitute for testing signal strength at each detector.
Key features
- Relays up to 128 wireless peripherals, so one repeater can cover a whole wing or floor.
- Communication range up to 1,000 m in open space.
- Two-way, frequency-hopping radio on 433.1 to 434.6 MHz with AES128 (Advanced Encryption Standard) encryption, the same as the hub and detectors.
- Automatic or manual pairing of peripherals.
- Built-in lithium battery with about 35 hours of standby, so the extended detectors keep reporting through a power cut.
- Alerts for low battery and for loss of its external power supply.
- Tamper alarm and a signal strength check to help choose the mounting spot.
- Keeps its settings through a power cut, and firmware updates arrive through the cloud.
What else you need
A Dahua 433 MHz W2 series wireless hub, such as the ARC3000H, and the peripherals it relays. It is powered by a 12 V DC, 1.5 A supply.
Installation
An alarm installer can survey and set it up. Place it indoors between the hub and the distant detectors, on a wall or a desk, use the signal strength check at the planned spot before fixing it, then pair the far detectors through the repeater.
Software and licences
Firmware updates are delivered through the cloud by way of the hub.
Before you buy
- Real-world range depends on walls and floors, so test signal strength at the planned spot before fixing it.
- The ARC3000H hub supports up to 4 repeaters.
- Indoor use only, -10 to 55 °C.
