It connects directly to the 230V mains supply and includes a built-in step-down transformer that reduces the voltage at the doorbell button circuit to a safe 8V. This eliminates the need for a separate external transformer, simplifying installation.\u003c\/p\u003e\u003cp\u003eThe BIM-BAM chime produces two distinct tones at 80 dB, audible across a typical residential room. The white plastic housing measures 170×106×50 mm and is finished for standard indoor environments. Volume control is not included; the device operates at its fixed 80 dB output. Connection is wired, and installation is by surface mounting on any standard wall.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-tone BIM-BAM electromechanical chime at 80 dB\u003c\/li\u003e\n\u003cli\u003eDirect 230V mains connection (nominal 230V~, 50Hz)\u003c\/li\u003e\n\u003cli\u003eBuilt-in 8V step-down transformer — no external transformer needed\u003c\/li\u003e\n\u003cli\u003eSurface-mount installation on indoor walls\u003c\/li\u003e\n\u003cli\u003eWired connection type\u003c\/li\u003e\n\u003cli\u003eIP20 ingress protection rating\u003c\/li\u003e\n\u003cli\u003eWhite plastic housing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThe built-in 8V transformer reduces the wiring circuit to the external door button to a safe low voltage, removing the need to purchase and house a separate transformer unit\u003c\/li\u003e\n\u003cli\u003eThe electromechanical BIM-BAM chime produces a familiar two-tone sound that carries clearly through interior walls without needing amplification\u003c\/li\u003e\n\u003cli\u003eSurface mounting allows the doorbell to be installed without recessing into a wall — suitable for existing buildings where wall modification is not practical\u003c\/li\u003e\n\u003cli\u003eDirect 230V operation means the doorbell is powered from the standard mains supply without any intermediate power supply\u003c\/li\u003e\n\u003cli\u003eAt 80 dB, the chime is audible in typical residential and small commercial environments without being excessively loud\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Orno OR-DP-BD-157\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Electromechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound:\u003c\/strong\u003e 2 BIM-BAM tones\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume:\u003c\/strong\u003e 80 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Voltage:\u003c\/strong\u003e 230V~, 50Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in Transformer Output:\u003c\/strong\u003e 8V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type:\u003c\/strong\u003e Wired\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection:\u003c\/strong\u003e IP20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (H×W×D):\u003c\/strong\u003e 170×106×50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume Control:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWhy You'll Love It\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo external transformer to buy, mount, or wire separately — the built-in unit handles the voltage step-down, keeping installation compact and clean\u003c\/li\u003e\n\u003cli\u003eThe familiar BIM-BAM tone is a standard two-tone chime that is immediately recognisable as a doorbell signal without any configuration\u003c\/li\u003e\n\u003cli\u003eSurface mounting means the doorbell can be positioned anywhere on an interior wall and relocated later without plastering over a recess\u003c\/li\u003e\n\u003cli\u003eWhite housing integrates naturally with standard interior wall finishes in homes, apartments, and shops\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Other","offers":[{"title":"Default Title","offer_id":56579138781566,"sku":"511512","price":31.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2250\/3550\/files\/15675225211262.webp?v=1779637476","url":"https:\/\/lynk.gr\/en-nz\/products\/other-orno-157-2-tone-230v-doorbell-with-transformer","provider":"Lynk.gr","version":"1.0","type":"link"}
