Loud outside, visible from the street, and awkward to reach · review
HUXGO's larger outdoor siren: 120 dB with adjustable volume and a strobe, a 5000 mAh backup battery, tamper protection, and pairing with up to ten HUXGO hubs.
The conclusion The siren for a long power cut and a multi-building property. Built for HUXGO systems.
The larger of HUXGO’s two sirens, and the differences are capacity and the number of panels rather than volume: both reach 80 m.
5000 mAh against 1000 in the smaller model. A siren’s backup cell exists for one situation — the mains has been cut — and capacity is how long it can go on sounding afterwards. That is the difference between a siren that protests for a while and one that is still going when anybody arrives.
Unusual, and specific. A property with a house, a workshop and a garage, each with its own panel, can share a single loud outdoor siren rather than installing three. If that describes your buildings, this is one of very few products that supports it.
It pairs with HUXGO panels on 433 MHz, at up to 80 m (262 ft) in open field — which is modest against the 868 MHz systems in this hub, and adequate across a normal property. HUXGO also states wired configurations without naming the contact, where the HXA-SB120 publishes an NC/NO input.
Larger and heavier, and it still belongs high on a visible elevation and out of reach. Height is what makes a siren awkward to silence; volume is only the second question.
A HUXGO installation across more than one building.

Time. A backup battery in a siren exists for the case where the mains has been cut, and capacity is how long the siren remains able to sound after that. Five times the cell of the smaller model means the siren survives a long outage rather than a brief one.
For a property with more than one building — a house, a workshop, a garage — each with its own panel, one loud outdoor siren serving all of them is cheaper and clearer than three. It is a specific arrangement and this is one of the few sirens that supports it.
HUXGO states “wired configurations” for integration with other siren systems, without naming the contact. The smaller HXA-SB120 in this hub publishes an NC/NO wired input: if your hub is from another maker, that is the model whose compatibility is written down.
