This door or window contact was a spare for my YALE SR alarm system which I have had to replace due to a siren fault. The box has been opened but the contact has never been used and still has the battery isolator plastic tag in place.All mounting parts are included - double sided adhesive strips and screws / rawlplugs etc. Please see photos. The Yale EF-DC Easy Fit Alarm Door/Window Contact is a white accessory designed for use with Yale SR and EF alarm systems. Manufactured by Yale Security in the United Kingdom, this security system component includes a battery and measures 110mm in length and 80mm in width.
