Onyx
Personal Alarm
Launched in 2013 as the world’s first jewellery-inspired pendant, the Cair Onyx combines discretion and reassurance. Its sleek design, discreet button, and integrated LED provide peace of mind while concealing vulnerability.







The latest Onyx features enhanced durability, a line-of-sight range of up to 600m, and up to 5 years of battery life. Fully interoperable with other major TEC suppliers, it’s our most advanced pendant yet.
Waterproof and versatile, the Onyx can be worn as a neck pendant or wristwatch. Pendants are available with a black neck cord or steel chain.



The Onyx now comes in chrome, carbon, and our full Onyx Rainbow collection: red, blue, green, yellow, and orange, allowing users to choose a style that suits them.







What Our Customers Say
“My mother is a lovely, feisty but frail lady. Despite being 93, she really wants to live in her own home for as long as possible. Her Onyx personal alarm is brilliant. It gives me the reassurance that she can summon help. It has saved her life when she had a bad fall. It is elegant and stylish as well. The peace of mind is invaluable.”
