The BS-2012WH is a wired magnetic contact for alarm and security systems. It is supplied in white and measures 1.3x2.8 cm, a compact size that suits most door and window frame profiles without being visually obtrusive. The unit consists of the contact body and a matching magnet, with an operating gap of approximately 3 cm.

Mounting is flexible: the included 3M adhesive tape allows tool-free installation on smooth surfaces, while the screw fixing option suits timber, PVC, and aluminium frames. Both methods can be used simultaneously for additional retention. The 44 cm AWG24 cable connects to a wired alarm panel or control unit.
