Siemens NET-7 ? Other

DescriptionThe Style 7 Network Interface Card, the NET-7 and NET-7M modules provide for a fully supervised Style 7 network interface between a main MXL panel and one or more MXLR remote panels. The network uses two RS-485 wire pairs for interconnection between panels. The NET-7 module provides, and supervises, two independent communication paths allowing system operation through both open and short circuits. The NET-7 should be located at the extreme points of the local MXL network (M-NET). This module determines what is installed in its enclosure and reports this information to the MMB where it is compared to the CSGM database. The NET-7M is located in the middle of the M-NET between the two NET-7?s. It allows for communication to additional MXLR remote panels, but it does not supervise the network. It must, therefore, be used in conjunction with NET-7s, but does not require a network address. Both the NET-7 and NET-7M incorporate diagnostic LED?s for use in system troubleshooting. They are approved for use in environments from 0?C to 49?Cand are listed by Underwriters Laboratories. UL and ULC Listed, and NYMEA, CSFM and City of Chicago Approved.
