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

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.

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.

Works great ! Easy to link with system and fit. Great add on to the Yale smart home sr 330

Prodotto di buona fattura ma estremamente costoso.

Great item - Easily connect to the Yale Alarm. Ive used the device on the front door. Clicked learn on the alarm, clicked the button on the device, the two pair up and were good to go. The door opens, the alarm now beeps to make me aware that entry has been gained. Ive tried and tested the alarm with the device by arming the alarm and then walking through the door unlocked and the it brings the street to a standstill with the noise.

Didn’t work returned faulty

Good quality product

Easy to change like for like

This thing makes my alarm go off when the door is opened. That was why I bought it.

Great price easy to add to an existing Yale alarm
