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

Easy to install

Semplice da installare e materiali di buona qualità. Ne ho acquistati 3 e tutti sono stati riconosciuti al primo utilizzo dalla base Yale. Una vitina rende semplice lapertura del dispositivo e la sostituzione della batteria. Ha anche dei distanziali per adattarsi a diversi tipi di porte/finestre.

Good quality item does exactly what sad on the box fits on most Windows and if not is easilly adapted to fit.

We ordered these to extend our system to cover some windows that overlook a flat roof upstairs. Our local neighbourhood news is that burglars have been breaking into properties with flat roof extensions because they quite often do not have cover upstairs and they then only steal from upstairs without triggering alarm systems downstairs. We installed eight of these in about an hour and then linked into system with great ease. We are very pleased that our house is even safer now than it was before. Great system.

If you have the HSA system this will not work

Does what it is supposed to do. On first ordering three of these and a remote keypad I received instead four of these and no keypad. A short conversation resolved the mistake and I had the missing keypad within 48 hours and the fourth contact free as compensation.

It does not work my tale system

Excellent accessories for Yale Wireless

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.

Very easy to install and just enough sensors for my small house so you may need to add extras. Really loud alarm. The only negative is the wireless router can be quite noisy when arming.
