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

Easy - works....

Great product. Easy set up. Super fast delivery

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.

ADDED THIS TO ALARM MY SUMMER HOUSE, BRILLIANT

Great price easy to add to an existing Yale alarm

Excellent piece of kit

Very good worked well with yale smart alarm

handy extra sensor for other doors/windows

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.

These products are great. I have them installed on every external door in the house. That is my front, back, utility, conservatory and garage door. I have programmed them all to beep on the control panel any time the contact is removed so I know when doors are opened in the house, even if the alarm is set or not. good range on them too. Battery life so far lasted 12 months!
