Overview

Life safety belongs in the same app as security: this unit combines a photoelectric smoke sensor with an electrochemical CO sensor, meets UL 217 and UL 2034, and links over the radio so that one alarm sets off every other Sentry in the building. The battery is sealed for ten years and the self-test runs weekly without you doing anything.

One alarm sets off the rest

Interlinking means the upstairs unit wakes you even if the basement one trips first.

Sealed 10-year battery

No more ladder every spring. The voice prompt tells you which room is affected, which saves time at 3am.

Loud and clear

85 dB at 3 m. I tested the CO side with a test gas can and it reacted in seconds.

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.
