Output connections

Connecting a SVMP2-8 to the SigNET iX LS

Triggers of the SVMP2-8 are wired to whatever external

equipment will be used to trigger them (e.g. switched relay or fire interface).

Set Options to Non-monitored mode

Connecting a SVMP2-8 to the SS2n (Network station)

Set Options to Non-monitored mode

Only using one message channel.

If you are only using one channel of the SVMP2-8, connect audio+

and audio- of both message connectors in parallel. This will ensure that there is no audio fault reported on
the unused channel.
