Overview
The Dahua ARA12-W2 is a small battery-powered indoor siren for Dahua wireless alarms. When the hub registers an alarm it signals the siren by two-way radio and the siren sounds, so people in a bedroom, upstairs hall or back office hear the alarm even when the hub itself is out of earshot. No cable is needed.
Is it right for you?
- Choose it to add a sounder in a part of the home, shop or office where the hub cannot be heard.
- It fits on a bracket with no wiring, so it suits rooms where running cable is awkward.
- It is for indoor use only. For an external bell box with a light, choose the ARA13-W2 (R).
- If you also want to talk to people in the room, the ARA14-W2 has an intercom.
Key features
- Three volume levels, with the high setting rated at 105 dB(A).
- Powered by two CR123A batteries, so no cable is needed.

- Signal strength check and test mode for confirming coverage after fitting.
