Configure the audio inputs
Left click to the right of the CPU and select an audio input card. In order to provide a
fail-safe source in the event of a processor failure, audio inserted via this slot will be rout-
ed to all zones. Therefore, this card will normally be used for a life-safety microphone.
For an all-call microphone(s), select the 1LS card. For a zonal mic., select the GPI card.
The 1LS card
Up to four emergency microphones can be connected to a 1LS card using four two-core
or two four-core fire resistant cables wired in ‘daisychain’ format (one after the other).
The default setting on this page is correct for an emergency microphone. However, the
1LS card can be used for any balanced audio input and the details are customised here.
For instance, you can alter the name of the microphone(s), change the names of switches,
change the audio type so that the correct output level is automatically selected and
change the Input Image to something more suitable, such as a green microphone for a
non-life safety microphone, or a CD for a CD player.
