About the HL-S3E-R8
The HL-S3E-R8 is a HiLook by Hikvision wireless interlinking smoke alarm.
If one alarm detects smoke, every linked alarm sounds, with no cables between them. They can link up to 1,000m apart in open space, or you can use one on its own.
The battery lasts around eight years. It has a hush button for false alarms, an infrared remote mute for alarms that are hard to reach, and a warning when the sensor needs cleaning. Screw and adhesive fixings are both in the box.

Suffix explained
Within this range, the R suffix denotes wireless interconnection capability and the trailing 8 denotes the 868 MHz radio band. The HL-S3E-R8 is therefore the 868 MHz interlinking variant, which is the correct band for use in the UK and Europe. Units must share the same radio band to interlink with one another, so keep a property on a single variant.

Installation guidance
- Ceiling mounted, with the edge of the detector at least 500 mm from any wall
- Fit multiple detectors where the ceiling run exceeds 10 m
- Keep at least 300 mm clear of heavy electrical cable runs
- Fix with the supplied screws and anchors, or with the supplied adhesive pad on smooth surfaces such as glass, metal, timber or sound latex paint
- Adhesive fixing needs 21 °C to 38 °C to bond properly and reaches full strength after 72 hours, so use screws below 10 °C or on rough surfaces
- Do not fit in kitchens, bathrooms or other damp areas, near air supply ducts or extract fans, above cookers, in dusty or insect prone spaces, within 1.5 m of fluorescent lighting, or in dead air spaces such as ceiling apexes and room corners
- Do not install in new or recently renovated buildings until all work is finished, as construction dust contaminates the smoke chamber
