The push button transmits at 433.92MHz using a digital coded signal to prevent interference from neighbouring doorbells or garage door openers, while the chime outputs a single 'ding dong' melody at 65dB when triggered.\u003c\/p\u003e\n\u003cp\u003eThe push button mounts to a door frame or wall using self-tapping screws and runs on a supplied CR2032 coin cell battery. A clear plastic cover on the front of the button protects a removable name card where house numbers or names can be written, making it useful for multi-occupancy properties or apartment blocks. The chime unit is a compact 120mm plug-free box that sits on a shelf, worktop or windowsill and runs on two AA batteries (not supplied), allowing it to be moved between rooms or floors without re-wiring.\u003c\/p\u003e\n\u003cp\u003eThe 50m operating range covers most residential properties, small commercial premises and outbuildings, though walls, metal structures and interference from other wireless devices can reduce effective range. The IP54 rating on the push button makes it suitable for external doors, covered porches and door canopies where direct rain contact is minimal. Both units use low-power components with extended battery life under typical residential use.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e433.92MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003eUp to 50m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume\u003c\/td\u003e\n\u003ctd\u003e65dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP rating\u003c\/td\u003e\n\u003ctd\u003eIP54 (transmitter only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery : chime\u003c\/td\u003e\n\u003ctd\u003e2x AA (not supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery : remote\u003c\/td\u003e\n\u003ctd\u003e1x CR2032 (supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions : chime\u003c\/td\u003e\n\u003ctd\u003e120 x 46 x 24mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions : remote\u003c\/td\u003e\n\u003ctd\u003e94 x 36 x 18mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight : chime\u003c\/td\u003e\n\u003ctd\u003e60g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight : remote\u003c\/td\u003e\n\u003ctd\u003e38g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/350295UK.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the IP54 rating mean it can be used outdoors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe IP54 rating on the push button indicates protection against dust and water splashes from any direction. It is suitable for external doors, covered porches and door canopies where direct rain contact is minimal, but should not be installed in fully exposed positions without overhead cover.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the operating range in real-world conditions?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe rated range is 50m in open space. Solid walls, metal structures, and interference from other wireless devices (WiFi routers, baby monitors) reduce this. In a typical residential property with cavity walls, expect 20-30m effective range. For larger buildings, test placement before final mounting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan multiple chimes be paired to one push button?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe product manual does not specify multi-chime pairing capability. The digital coded signal prevents interference from neighbouring doorbells, but whether multiple receivers can respond to a single transmitter depends on the internal pairing protocol. Contact us for confirmation before purchasing multiple chime units.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do the batteries last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBattery life depends on usage frequency. Under typical residential use (5-10 presses per day), the CR2032 in the push button can last 6-12 months, while the AA batteries in the chime last 3-6 months. The specification sheet notes low power consumption on both units.\u003c\/p\u003e","brand":"AVSL","offers":[{"title":"Default Title","offer_id":45313415905547,"sku":"350.295UK","price":6.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/350295UK_CO1_61f6cda1-065e-452d-8fdf-d8733b114c1b.jpg?v=1715192650","url":"https:\/\/niori.co.uk\/products\/mercury-wireless-waterproof-doorbell-with-portable-chime-white","provider":"Niori","version":"1.0","type":"link"}
