BMS/Graphics Interface
The Mxp-010 interface allows BMS systems and graphics PCs to be integrated with the Mx-
series of Fire Control Panels and Remote Terminals.
The interface is an integral part of the Ad-Net network, handling all the network traffic, prioritisation, etc. whilst allowing the external BMS/Graphics systems to issue commands and receive information over a simple RS232 bi-directional serial port. Multiple interfaces can be connected at different positions on the network as required (following the normal Ad-net Network rules to give each node it's own unique network address, etc.).

Mounting the enclosure
The enclosure is provided with four M3 fixing
points. Refer to the diagram opposite for
dimensions. Use appropriate fixings to mount
the enclosure on the wall. Ensure that there is sufficient space to allow the cover to be removed / opened when the panel is finally mounted. If the cover is completely removed, remember to reconnect the earth lead prior to re-assembly. Wiring
The unit is designed for easy wiring installation.

Default Settings
The following factory default settings are used, but these can be changed as required.
Interface Zone 200 RS232 Baud Rate 38400 Note that if multiple BMS/Graphics interfaces, or other network interfaces, with the same default settings are used it is essential to change the defaults to give unique parameters for each interface. Changing the Interface Settings
The above defaults can be changed as required after moving switch SW1 over to the "Commissioning" position (i.e. move to left). Use any of the following: - Connect a PC to the RS232 connector and run the "Virtual Terminal" display and select "Setup" from the virtual display Connect a PC to the RS232 connector and using the MX configuration software, transfer a file from the PC to the Interface. "Zone Text" should also be entered for the interface, so that any events created by the BMS/Graphics Interface can be readily identified from displays throughout the fire system network. Normal Operation
If a display has been used to configure the interface, then check that all commissioning
operations are complete, with the display showing "[Commission]" in the top left corner of the
Ensure the RS232 connections to the BMS/Graphics system are made, then move switch SW1 out of "Commissioning" (i.e. move switch to right). Maintenance
Lithium Battery

WARNING – A lithium battery is used for data retention / operation of the real time clock.
Replace only with the same type or authorised equivalent. This battery is not rechargeable.

Expected Shelf Life Replacement Schedule - 10 years for panels in continuous service 10 years for spares (i.e. when the panel / board is not powered) Replace if the battery voltage falls below 2.6 volts. Manufacturer / Part Number - CR2032
