Hi GotTheTshirt, thanks for replying.
The first one is ST01554AT, this is an expansion of three parameters for the DFDR. Originally Allied Signal then Honeywell who sold the STC to L3 I think.
Second one is SA3165NM, this is the Floor proximity emergency escape path lighing. This is an odd one, the lights are mounted on each seat row. Manufactured by Bruce. Information about this one is very scarce.
About the FAA site, yes I've checked it. Doesn't help me though.
This bloody EASA is going to be the end of all reason and aviation.
