Key exchange box B

OPERATION Castell Key Exchange Boxes are used in various applications to control multi-door access to hazardous areas. USAGE B key exchange boxes should be used to allow a safe access to potential hazardous and dangerous areas with one or more access points. The B key exchange box is not designed for security purposes, such as access to a building. No hazardous substances were used in the manufacture of this product. INSTALLATION The B key exchange box should normally be mounted on a static frame using suitable fasteners. Please refer to the drawing on page 4 for maximum and minimum mounting distance. The B key exchange boxes are available in horizontal and vertical mounting versions. IMPORTANT: The B key exchange box should be mounted using anti-tamper fasteners to prevent unauthorised removal. The B key exchange box must be installed by a competent and qualified person who has read and understood these instructions. Please retain this document in your technical file. The manufacturer should be consulted when use in a corrosive environment is planned. APPLICATION A typical application of the B key exchange box is machine guarding with one or more access points to the hazardous area. The B key exchange box safety component is used as a part of an integrated safety system, which ensures a machine is shut down, before access to the hazardous area is allowed. The system involves a KS key switch for the electrical supply and typically more than one AIE access interlocks for full body access. The removal of the isolation key from the key switch isolates the electrical supply to the machine. This key is taken to the B key exchange box to release the trapped keys.
