Description
This magnetic door contact can be used in most security systems up to and including grade 3 and environmental class II as specified in EN50131-1 and is certified to EN50131-2-6 by Kiwa FSS.
It operates as a normally-closed circuit which opens 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. The contact is also protected against tampering with optional detection of removal from its mounting surface. Additionally there is a magnetic interference detection circuit for signalling the proximity of a magnet, which is typically used by an intruder trying to inhibit the performance of the contact.
