Good, and easy to extend

We added the glass-break sensor a month in. The gateway made extending the system painless.

Smoke alarm is the real bonus

Interconnect works across both floors. The 24-month warranty covers the whole kit, which is unusual.

Solid, and clearly documented

The installation guide actually matches the hardware. The keypad reader is a nice addition for a small office.

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 105 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.
