Who is the HL-S3E for?

A wireless smoke alarm with a sealed 10-year battery that links to other HL-S3E units, so when one detects smoke they all sound — the interlinking that Scottish and many landlord regulations now require, without running cable between rooms. It also pairs to a HiLook alarm panel (A201P / A201PS) so a fire alert reaches your phone even when you’re out — which a standalone smoke alarm can never do. Fit one per floor as a minimum: landing, hall, and any room with a high fire risk.

Frequently asked questions

Does it work on its own?

Yes — as a standalone or interlinked smoke alarm without any panel. The panel adds the phone notification.

How many can be linked?

Multiple units interlink so the whole house alarms together; the exact maximum is on the datasheet.

Is the battery replaceable?

No — it is sealed for 10 years, after which the unit is replaced; a low-battery chirp warns you first.
