300M Range SOS Button EU Plug

A dedicated wireless emergency response system comprising one mains-powered receiver (EU plug, 230 V AC) and one portable SOS call button. The button is sized at 5.5 x 3.5 x 1.2 cm and weighs 28 g, with a fixed lanyard for secure wearing or carrying. It carries an IPX4 waterproof rating — appropriate for incidental moisture exposure in bathrooms, but not for immersion or high-pressure water contact. Power for the button comes from a single CR2032 coin cell (not included); the receiver draws power directly from the wall outlet. Activation triggers dual-mode notification: audible alarm (selectable among 12 tones, adjustable from silent to 90 dB) plus simultaneous red LED flashing on the receiver. Signal range achieves up to 300 metres in line-of-sight conditions; structural barriers like concrete walls or metal doors will reduce effective distance. For best results, position the receiver within clear sight or minimal obstruction of common activity zones. Tone selection follows a simple two-step process: hold the volume button *prior* to plugging in the receiver. Once powered and the status light illuminates, release the button and press the music button repeatedly to cycle through all available melodies — no external devices or software required.
