1) ROUTER 1 port is used for connection to the Router as standard.
Use ROUTER 2 port if the MPS firmware is V1.5.20 or earlier.
2) ROUTER 2 port is used for connection to the ‘B’ Router in a dual interface connection
with ‘A’ and ‘B’ Routers.
3) ASL protocols supported on the serial connection: ASL Serial, Paging (DMS) and
Console (ACU). The protocol is defined by the host, and the MPS will automatically
discover the protocol upon connection.
4) Emergency Microphones that are used as location for display of mandatory EN 54-16
indications and controls should have dual power supply: one power supply connected
to ROUTER 1 port, and the other power supply to ROUTER 2 port.
5) DC power supply via Router connections: see Figure 16 (page 17) for required link
