CQR Aluminium Surface Contact
This heavy duty surface mounted magnetic contact can be used in most security systems up to grade 3 as specified in EN50131-1 and is compliant with EN50131-2-6 and environmental class II (for use indoors). 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 doors and windows to detect the unauthorised entry of an intruder. A number of applications are shown over. The contact is sealed to prevent access to inside of the unit. Additionally there is a magnetic interference 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.
