Overview
The Dahua ARA14-W2 is a wireless indoor siren with two-way talk for Dahua 433 MHz alarm systems. When the alarm triggers it sounds and flashes, and its microphone and speaker let you speak to whoever is in the room from the Dahua app, whether that is an intruder to challenge or a relative who pressed the panic button. It suits homes with elderly family members, clinics, small shops and offices.
Is it right for you?
- Choose it where someone may want to talk after an alarm: a home with an elderly relative, a clinic, a shop or an office.
- The built-in panic button lets a person in the room call for help without a separate button.
- It is for indoor use only. For an external bell box, see the ARA13-W2 (R) outdoor siren.
- If you only need a loud sounder with no talk, the ARA12-W2 is simpler and smaller.
Key features
- Siren up to 100 dB(A) at 1 m, adjustable down to 77.6 dB(A).
- Two-way audio: the microphone picks up speech from up to 5 m away and the speaker plays at up to 85 dB.
- Voice talk through the app and over SIP.
- Built-in panic button and custom voice prompts.
- Several alarm sounds with red, blue and green indicators.
- Two-way 433 MHz radio: alarm range up to 1,200 m and intercom range up to 800 m in open space, with frequency hopping and AES128 encryption.
- Tamper alarm, low battery detection and cloud updates through the hub.
- Runs on four CR123A batteries or a 9 to 15 V DC supply.
What else you need
A Dahua 433 MHz wireless alarm hub whose firmware supports intercom sirens. Check this before ordering. The manufacturer lists it as compatible with Hub2 and Repeater Pro.
Four CR123A batteries, or a 9 to 15 V DC supply where the intercom will be used often.
Installation
An alarm installer should fit and pair it, then set the sounds and talk options in the Dahua app.

Before you buy
Indoor use only, from -10 to 55 °C.
