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

Good product and fast delivery

Used them for outbuildings. No issue with range. Does what it says on the tin. :)

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.

Be careful advertiser on Amazon as being compatible with my smart living alarm, they are not.. what a waste of money plus the return option only suitable for those who want to drop off.. I live in Ireland and can’t return them as there isn’t a postal option

Easily to install! Once attached sticks well! Great product

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.

Bought as an extra door contact for my existing Yale Easy Fit 2 alarm and worked a treat. Came with all the necessary fixings and was cheaper than elsewhere.

Value for for money, good product as described, easy to assemble, doing what it says on the description, recommand to anyone who are looking to buy.

excellent item - got on a special offer price

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