Magnetic Door Sensor Chime

This wireless door chime system includes a compact magnetic sensor and an AC-powered receiver. Sensor dimensions: 2.4 x 1.2 x 0.6 inches (61 x 30 x 15 mm), weight: 1.8 oz (51 g); receiver dimensions: 3.5 x 2.2 x 1.1 inches (89 x 56 x 28 mm), weight: 4.2 oz (120 g). Powered by 2 x AAA batteries (not included) for the sensor and standard UK mains for the receiver. Wireless transmission reaches up to 500 feet line-of-sight, with robust performance through interior walls typical in UK terraced housing. Supports unlimited additional sensors — each configurable with its own of 26 melodies and one of 5 volume settings. LED indicators show operational status, and memory function preserves your last-used chime and volume selection after unplugging or power interruption. Designed for real-world UK use cases: alerting parents to children leaving bedrooms at night, reminding carers when someone with early-stage dementia approaches an exit, or notifying shop owners of walk-in customers during quiet hours. Mounts instantly on wooden, uPVC, or metal doors and windows using industrial-grade double-sided tape — no screws, no damage, no landlord permission required. The system’s flexibility makes it suitable for layered security: assign ‘Chime 7’ to the front door, ‘Chime 19’ to the garden gate, and mute the nursery door during nap time — all managed from one receiver.
