Yale EF-DC Easy Fit Alarm Door/Window Contact, White, DIY Friendly, Accessory for SR & EF Alarms, Suitable for Main Access Points

Very pleased with item and delivery. They are add on for my Yale alarm

second purchase of these additions for my alarm system, easy to install and set up, no problems as long as you get the 2 components as close as possible without them damaging each other.

Easy to set up and control, no drilling needed as the sticky pads are plenty strong enough. There are holes for screws should you need them

Very professional and easy to use

As described.

Bought YALE alarm kit - needed extra door/window sensors. Worked perfectly - was up and running within minutes.

Easy to install and connect

Prodotto di buona fattura ma estremamente costoso.

Good quality product

Good value for money
