Description
The REP-1 is an optional MXL module that extends the distance of the MXL’s RS-485 network. The REP-1 provides the ability to support various wiring configurations including series and star configurations. The REP- 1 provides the ability to support NFPA Style 4 or Style 7 network communications wiring. The REP-1 can be used to provide network wiring between MXL panels or MXL and MXLR panels. The REP-1 is a one-half slot card that plugs into a MOM-4 or MOM-2 cardcage. The REP-1 allows MXL network distances to be expanded to allow greater application flexibility. The REP-1 is an RS-485 repeater module capable of being configured as one Style 7 or two Style 4 network communication lines. The REP-1 provides the ability to convert from a Style 7 network to a Style 4 tap.
This Style 4 tap can be used for annunicators that may not require Style 7 wiring (such as RCC-1 or MOI/MOD-16). Using the REP-1 expands the MXL, MNET or XNET node count to 64. In MXL configurations which require network distance in excess of 5,000 feet of copper wire, the REP-1 provides greater network wire distances in either straight or star configurations. Up to two REP-1s may be connected in series, with no limitation in the number of REP-1s in an MXL system with star configuration wiring. This equipment is approved for operation over the temperature range of 0°C to 49°C.
Engineer and Architect Specifications
The REP-1 shall be an RS-485 network repeater module and shall provide two Style 4 or one Style 7 network communication line(s). The REP-1 shall occupy a single one-half MOM-4 or MOM-2 cardcage slot. REP-1 shall provide network communications between the MMB and PSR or MOI as well as between MMB/NIM-1R and MMB/ NIM-1R. RS-485 communication shall be supported for NFPA Style 4 or Style 7 in any combination of serial or star type wiring configurations.
