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

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

Very easy to pair with the system and easy to fit.

Good quality product

Great product. Easy set up. Super fast delivery

Works great with the Yales Smart alarm. Easy to pair

Paired easily with current Yale alarm

Really simple to install - especially if replacing a faulty one as the back part which is screwed into the wall can stay in place. I always find these devices quite expensive for what you get, but they do the job well.

Works, but it is a shame they are so chunky

Really easy to fit and link up to my current alarm system. Needed to replace the old door contact and it was a like for like replacement, so all very straight forward. Peace of mind again.

The range is worse than the Yale 6000 series one. Otherwise it is okay, neat and nice.
