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

I have 3 of these installed, I would say the realistic range of the wireless is 15m (in a house), not 30m as stated. Otherwise, extremely easy to fit and link up to the alarm.

Quickly despatched and good value set

Easy to link into the Yale Home System

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.

these addons to my system were easy to fit and work perfectly as does the whole system would recomend

I have the Yale Smart Living Home Security System, that I purchased in the UK and brought the System over to Spain, where I now live. I wanted to have a spare Door/Window Contact. It took nearly 3 months to be delivered to my address in Spain, as the goods were detained in Customs, until additional paperwork was supplied. Pleased to have had it finally delivered. It is a good home security system.

I have it on my conservatory doors so i will know if anyone comes in without me inviting them in

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

love this for peace of mind and safety. We brought it to go with the full Yale alarm system as an extra. Works well and easy to install.

Extremely easy to install, easy to replace batteries, and easy to control once set up. The batteries also lasted me a year before I had to replace them so thats a good benefit to these. Not much to it, they do their job properly, no complaints yet even after a year use.
