For other uses, see Burglar alarm. An intrusion detection system (IDS) generally detects unwanted manipulations of computer systems, mainly through the Internet. communicates all alarm and supervision information, including audio, on the same integral fiber transponder A receiver/transmitter on a communications satellite. It receives a microwave signal from earth (uplink), amplifies it and retransmits it back to earth at a different frequency (downlink). A satellite has several transponders. . Using the fiber communication method, it interleaves the signals and audio outputs while eliminating the need for any additional fiber communication boards. Its zones report to the MXF-5000 fiber series multiplex See multiplexing. control unit, which can handle up to 60 zones of equipment. Features include a redundant fiber ring to ensure communication integrity of the system. The control unit also integrates with video and other equipment via relay relay, electromechanical switch operated by a flow of electricity in one circuit and controlling the flow of electricity in another circuit. A relay consists basically of an electromagnet with a soft iron bar, called an armature, held close to it. outputs or RS-232 ports. CIRCLE #508 FOR INFORMATION |
