ALL CALL FIRE MICROPHONE INPUT BOARD
This card is normally used for an all-call fi reman’s microphone, but can also be used for normal paging microphones or any balanced line level audio source and may be routed to any pre-defi ned combination of zones.
Up to 4 paging units BM 4631WM (or only one paging unit BM 4601) can be connected to one IB 4001FM card and they will work on a fi rstcome- fi rst-served basis. When multiple inputs are connected to a single card, they must all page the same audio zones. The card also has two additional monitored switch inputs that are normally used to manually trigger the emergency messages, but can be used for any purpose. The card provides full monitoring of the fi reman’s microphone(s) in accordance with EN 60849 and a fault will result in a text message being logged and displayed.
