System Description
Input signals to the director control these signs:
-
the NO SMOKING and FASTEN SEAT BELT lighted signs in the cabin,
-
the RETURN TO SEAT signs in the lavatories,
-
the EXIT signs. Manual commands are received from the cockpit NS and FSB switches. These are grounded inputs NO SMOKING COMMAND or NO SMOKING AUTO, and grounded input FASTEN SEAT BELT COMMAND respectively. The director interprets open circuited NS inputs and open circuited FSB input as NS OFF and FSB OFF commands respectively. Director software uses data from the CAM to activate signs which opened on:
-
the cockpit commands,
-
the discrete inputs LANDING GEAR DOWN LOCKED,
-an EXCESSIVE ALTITUDE.
-
the NS AUTO input, The director also provides NS AUTO input for the optional NS AUTO flight compartment commands. The interface to the EXIT signs is via a connection from the director to the emergency lighting system. DEUs type A drive and interface all other signs. The director addresses each sign independently via DEU
A.
Switching on of any signs is signalled to the SDAC via the respective director output NO SMOKING. Switching on of any NS sign is also signalled to the EMLS.
