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

Didn’t work returned faulty

I bought this to add to the new system I was having in stalled.

Added to our system and work perfectly. Batteries run out quite quickly

Easy to fit and program ..spot on

Easy to fit and great price!

Rather expensive for what you get. However, easy to add to my existing system and the adhesive pads I was worried wouldnt stick were actually very good.

Dont bother. Doesnt work with existing kit. Contacted Yale and they dont reply. Not sure what this is for as it doesnt connect to a system which you have bought separately.

Easy to install and link up to any existing or new system. The battery life is great, haven’t had to change in 2 years. Fit on most doors and windows even if the window/door and the frame aren’t flush.

Cheap and cheerful

We are very pleased that our house is even safer now than it was before. Great system.
