CQR, SC570/BR/G3/EN, 6 Terminal Surface Contact - Brown (G3)

This contact is a modern stylish magnetic door contact that can be used in most security systems up to and including Grade 3 as specified in EN50131-1:2006 and is certified to 50131-2-:2008 and enviromental class II (for use indoors) by Telefication. IT operates as a normally closed circuit going open when the magnet housing is moved away from the contact housing. 

This Contact can be used on windows and doors to detect the unauthorised entry of an intruder. A number of applications are shown below. the contact is also protected against tampering with the option of detection of removal fromn its mounting surface if required. 

Addintionally there is a magnetic interface detection circuit for signalling the proximity of a magnet, which typically would be used by an intruder trying to inhibit the performance of the contact.
