Smart Alarm Systems

Doors and windows are the first place to protect, and our Smart Alarm Systems UK collection focuses on app-connected alarm kit for the home. A smart alarm alerts your phone when a sensor is triggered, so you know straight away if something is opened while you are out. It suits homeowners, renters and anyone building up a home security system step by step. Adding sensors to more entry points is a simple way to extend coverage over time.

The Yale Sync door and window contact sensors come as a 2 pack and work as an accessory for the Yale Sync smart alarm, with a stated range of up to 200m. Contact sensors sit on a frame and its door or window, triggering when the two parts separate. They are a quick way to add protection to back doors, patio doors and ground floor windows. Expanding an existing smart alarm with extra sensors is often more cost-effective than replacing the whole system.

We show the full product name and pack size for every alarm accessory, making it clear which system it works with. Yale is a long-established security brand, and our prices are kept competitive with leading UK retailers. Listings are reviewed before publishing so compatibility details are accurate. Our UK team can help you confirm that sensors will pair with your current alarm.

A smart alarm gives you instant alerts and greater peace of mind. Check compatibility, then add the sensors you need for every entry point. Tech Accessories Store is here to help you secure your home.
