PoE (Power over Ethernet): see Figure 16 (page 17) for required link settings
•
The Ethernet port can be used for digital audio I/O and for configuration purposes
•
Ethernet and PoE connections do not provide EN 54-16 compliance
•
ASL protocols supported over IP: ASL Serial, TRL (Transactionless) and Paging (DMS).
The protocol is defined by the host (if any), and the MPS will automatically discover the
protocol upon connection.

Used to provide hardware bypass and listen-in functions
•
Hardware bypass is provided on inputs 1 and 2 of ASL Voice Alarm Routers
•
Used in addition to one or both standard ASL microphone ROUTER 1 and ROUTER 2
ports below
•
Routers with All Call LED connection: a pull up resistor (10 k Ω / 0.25 W) to +V supply is
required in order to suppress the All Call LED fault
