110 dB is not an exaggeration

We tested it and the neighbours came outside. The amber strobe is visible from the corner of the street.

Survived a winter outside

IP65 and it has been through storms and hard frost without a flicker or a false trip.

Backup battery does its job

Eight hours on battery during an outage. It is genuinely loud, so warn the neighbours before you test it.

Questions about this product

Still unsure? Ask us
How many sensors can the hub handle?

The gateway pairs up to 30 sensors. The spec table lists supported types; the door/window, PIR, glass-break and smoke kits all connect to the same hub.

Do I need a monitoring contract?

No. The siren and strobe are self-contained. If you want 24-hour monitoring, the hub can connect to a monitoring service, but it is optional.

How loud is the siren?

The siren is 110 dB at one metre, loud enough to be heard across a street in normal conditions.

Can I extend the system later?

Yes. Add sensors one at a time from the hub settings; the quote cart makes mixing and matching parts easy.
