Product Overview
The Dahua DHI-ARA24-W2 is a compact 4-button wireless keyfob for Dahua's AirShield wireless alarm platform, giving you Home, Away, Disarm and SOS control from your keyring without walking to a keypad. It communicates with the alarm hub over an encrypted, frequency-hopping 433MHz link rated to 500m in open space, so it stays responsive even at the far end of a property.
A single CR2032 coin-cell battery keeps it running for years between changes, and a two-colour status LED plus low-battery warning mean you always know it's working before you rely on it. Supplied directly through Total Security Equipment.

Why Choose This Keyfob
This is a genuine Dahua accessory for the AirShield wireless alarm platform, so it pairs cleanly with a compatible Dahua alarm hub without the reliability issues of a generic aftermarket remote. Encrypted two-way communication and frequency hopping keep the link resistant to interference and jamming attempts, and the long CR2032 battery life means it's a low-maintenance addition to a system rather than one more thing to remember to charge. Available from Total Security Equipment.

FAQs
1. Will this work with any alarm panel?
No — this keyfob is built for Dahua's AirShield wireless alarm platform and pairs with a compatible Dahua hub, such as the ARC3000H series. It is not a universal remote for other brands. Check with our team if you're unsure whether your existing system is compatible.
2. What do the four buttons do?
Home arms selected zones for at-home protection, Away arms the full system, Disarm switches the system off, and SOS sends an immediate emergency alert.
3. How long does the battery last?
It runs on a single replaceable CR2032 coin-cell battery, with a typical life of a few years under normal use — the fob will show a low-battery warning before it needs replacing. Confirm the exact expected lifespan with our team.
4. What's the difference between this and the 868MHz version?
This DHI-ARA24-W2 is the 433MHz version used in Australia. Dahua also makes a DHI-ARA24-W2(868) variant for regions using 868MHz — the two frequencies are not compatible with each other, so make sure you order the version that matches your hub.
5. Where can I buy this keyfob in Australia?
It's available directly from Total Security Equipment.
