Overview
The Dahua ARM7012-W2 is a wireless WallSwitch, a small relay module that switches mains-powered equipment under the control of a Dahua 433 MHz alarm hub. It also measures the voltage, current and energy used by whatever is connected. It suits a home, shop or office that wants to switch lights, a water heater, a pump, signage or an appliance from the Dahua app, on a schedule, or automatically when the alarm is set or triggered.
Is it right for you?
- It suits mains loads of 100 to 240 V AC up to 13 A, fitted inside a switch box or near the load.
- For a low-voltage dry-contact job such as a gate or lock trigger, the ARM7011-W2 is the matching model.
- Heaters and motors with a high starting current need checking against the 13 A limit.
- Indoor use only, -10 to 55 °C.
Key features
- One relay output, normally open (NO) or normally closed (NC), rated 100 to 240 V AC at up to 13 A.
- Voltage, current and energy consumption monitoring, so you can see what the connected load uses.
- Overheat and overload protection.
- Jamming detection, frequency hopping and AES128 (Advanced Encryption Standard) encryption on the radio link.
- Cloud update with automatic recovery if an update fails.
- Up to 800 m open-space range, and a test mode for checking the link.
- Small 39 x 33 x 19 mm body that fits in a standard switch box.
What else you need
A Dahua 433 MHz wireless alarm hub and the Dahua app. The module is powered from the mains it switches (100 to 240 V AC, 50/60 Hz).
Installation
A qualified electrician must fit it, because it is connected to live mains inside a switch box or next to the load. Isolate the circuit, wire the supply and the load, then pair the module with the hub and set its schedules and scenes in the Dahua app.
Software and licences
Switching, schedules, alarm-linked scenes and energy readings are managed in the Dahua app. Updates arrive through the cloud.
Before you buy
- Live mains wiring: have an electrician fit it.
- Check that the load stays within 13 A, especially heaters and motors with a high starting current.
- For low-voltage switching use the ARM7011-W2 instead.
- Indoor use only.
