Overview
The Dahua ARM7011-W2 is a small wireless relay module for a Dahua 433 MHz alarm system. It gives the alarm hub one dry-contact output that it can switch on command from the app, on a schedule or when an alarm is triggered. It suits a home, shop or office that wants the alarm to open an automatic gate or garage door, release an electric lock, switch on a 12 V light or sounder, or reset a device remotely.
Is it right for you?
- It suits low-voltage loads: the output is rated 0 to 36 V DC at up to 5 A.
- It is not meant for switching mains. For a 230 V load such as a light circuit or water heater, the ARM7012-W2 is the matching model.
- It is small enough (39 x 33 x 19 mm) to fit inside a gate controller or equipment housing.
- Indoor use only, -10 to 55 °C.
Key features
- One relay output, normally open (NO) or normally closed (NC), rated 0 to 36 V DC at up to 5 A.
- One input for tamper, so the hub knows if the module is opened.
- Overvoltage and overheating protection.
- Up to 800 m open-space range on two-way, frequency-hopping radio with AES128 (Advanced Encryption Standard) encryption.
- Test mode for checking the link, and firmware updates through the cloud.
- Powered by 7 to 24 V DC, so it can share the supply of the gate, lock or lighting it controls.
What else you need
A Dahua 433 MHz wireless alarm hub, the Dahua app for pairing and scenarios, and a 7 to 24 V DC supply. Check the current rating of the load and the wiring of the gate or lock controller before connecting.
Installation
An alarm or gate installer should fit it. The module is wall mounted or placed inside the equipment housing, wired to the DC supply and the load’s control terminals, then paired with the hub and assigned to scenes in the Dahua app.
Software and licences
Pairing, schedules and alarm-linked scenarios are set in the Dahua app. Updates arrive through the cloud.
Before you buy
- Not for mains loads: use the ARM7012-W2 for 230 V equipment.
- Keep the load within 36 V DC and 5 A.
- Indoor use only.

Questions about this product
Can it switch a mains light or heater?
No. The output is rated 0 to 36 V DC at up to 5 A. For mains loads use the ARM7012-W2.
What power does it need?
7 to 24 V DC.
How far can it be from the hub?
Up to 800 m in open areas. Walls and floors reduce this, so test the link in test mode before fixing it.
Can it open my gate or garage door?
Yes, if the gate or door controller has a low-voltage trigger input. Check its wiring and current rating before connecting.
Does it need an internet connection?
The hub needs its own connection for app control. The relay itself talks to the hub by 433 MHz radio.
