- Description
- An analogue-addressable optical smoke and heat detector. The detector utilises the light scatter sensing principle, using both infra-red and blue light emitting diodes (LEDs) and a photodiode as the smoke sensing element. This provides a more accurate measurement of the sizes of particles found within its sensing chamber. By calculating the ratio of these light sources, which operate at different wavelengths, it can determine the particle size and thus distinguish between smoke and non-combustion products such as steam droplets or dust. Heat detection is made using a thermistor of low thermal mass, which can be set to detect temperature rate of rise or to trigger at a fixed ambient temperature. The product comprises a circular abs-type plastic casing containing metal fastenings and connecting terminals plus a populated printed circuit board with the smoke sensing chamber attached; plus, an externally mounted thermistor and a further external 360-degree led. It also incorporates a chemically etched stainless steel insect screen to minimise ingress of insects and airborne contaminants. The primary function of these products are the detection of smoke. The detector is used in conjunction with a fire alarm system control panel. It does not contain an integral recording device nor any audio-visual warning equipment. It has remote indicator output. The detector may be sold singularly in a small cardboard box but is more commonly despatched within larger cardboard cartons containing 10 or 100 units.

- Justification
- Classification has been determined in accordance with the following: For the purposes of determining the commodity codes within which goods most appropriately fall, reg 3 (1) of The Customs Tariff (Establishment) (EU Exit) Regulations 2020 sets out that the rules of interpretation contained in the following have effect – a. Part Two (Goods Classification Table Rules of Interpretation) of the Tariff of the United Kingdom (Reg 3(1)(a)); and b. Notes to a section or chapter of the Goods Classification Table (Reg 3(1)(b)) General Interpretative Rules (GIRs) GIR 1 has been used to classify this product by the terms of heading 8531 - electric sound or visual signalling apparatus (for example bells, sirens, indicator panels, burglar, or fire alarms GIR 5(b) has been used to identify the type of packaging GIR 6 has been used to classify the goods to subheading level - 853110 - burglar or fire alarms and similar apparatus 8 digit-code 85311030 - of a kind used for buildings Also classified in accordance with: Harmonised System Explanatory Notes (HSENs) 8531 Note(F) (4) Harmonised system explanatory (HSENs) Note (E) to 8531
