The DEFED ALARM KIT is a set of high-performance security products. These are characterised by an understated appearance, harmoniously coordinated in a homogeneous style, and permit discreet integration into modern architecture. Thanks to their anti-tamper design, the products are secured against removal by force and sound the alarm if any of them is touched, struck or destroyed without authorisation. The service life of the battery is up to two years, thus contributing to reliable burglary protection.
