It uses a unique MCU and photoelectric signal design to detect both smouldering and flaming combustion smoke while resisting false triggers from dust, insects, and optical interference.\u003c\/p\u003e\u003cp\u003eWhen smoke density reaches the alarm threshold, the built-in photoelectric sensor activates the alarm at ≥85 dB at 30 cm and transmits a wireless signal to the Helio main panel. The detector is certified to BS EN 14604:2005 and runs on a single 9 V battery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePhotoelectric smoke detection — responds to both smouldering and flaming smoke\u003c\/li\u003e\n\u003cli\u003eDust-proof, pest-proof, and anti-optical-interference MCU design\u003c\/li\u003e\n\u003cli\u003eBS EN 14604:2005 certified\u003c\/li\u003e\n\u003cli\u003e≥85 dB alarm sound at 30 cm\u003c\/li\u003e\n\u003cli\u003eWireless transmission at 433.92 MHz, up to 500 m without obstacle\u003c\/li\u003e\n\u003cli\u003eLow battery warning\u003c\/li\u003e\n\u003cli\u003ePowered by 9 V battery (1 × 6F22 \/ 6LR61)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePhotoelectric detection catches slow smouldering fires that may produce significant smoke before open flame develops\u003c\/li\u003e\n\u003cli\u003eDust and pest resistance reduces nuisance alarms from environmental contaminants in kitchens or utility rooms\u003c\/li\u003e\n\u003cli\u003eBS EN 14604:2005 certification confirms the sensor meets European standards for residential smoke alarms\u003c\/li\u003e\n\u003cli\u003eThe compact circular form (Ø 107 mm × 34 mm depth) fits discreetly on a ceiling without requiring a separate base or relay\u003c\/li\u003e\n\u003cli\u003e500 m transmission range ensures the signal reaches the Helio panel even across multi-storey properties\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e DSKH4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Voltage:\u003c\/strong\u003e DC 9 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e 9 V (1 × 6F22 \/ 6LR61)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Current:\u003c\/strong\u003e ≤100 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby Current:\u003c\/strong\u003e ≤20 μA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlarm Sound:\u003c\/strong\u003e ≥85 dB at 30 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e BS EN 14604:2005\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Distance:\u003c\/strong\u003e 500 m (without obstacle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission Frequency:\u003c\/strong\u003e 433.92 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Temperature:\u003c\/strong\u003e -10°C to +50°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity:\u003c\/strong\u003e ≤90% rh (non-condensing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 98.7 g (without battery); 134.5 g (with battery)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Ø 107 mm × 34 mm depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIntegrates directly with the Helio panel — smoke detection triggers the full system response, including siren and app alert\u003c\/li\u003e\n\u003cli\u003eThe circular disc form factor installs flush on any standard ceiling junction box in minutes\u003c\/li\u003e\n\u003cli\u003eAt ≤20 μA standby current, the 9 V battery provides extended service between replacements\u003c\/li\u003e\n\u003cli\u003eA single unit type handles both smouldering and flaming fires, avoiding the need for multiple detector types\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Other","offers":[{"title":"Default Title","offer_id":56579029827966,"sku":"225022","price":37.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675204665726.webp?v=1779636956","url":"https:\/\/lynk.gr\/en\/products\/other-dinsafer-helio-wireless-smoke-sensor-dskh4","provider":"Lynk.gr","version":"1.0","type":"link"}
