FTB Revelation any audible alarms?

[DrDurandal]

Looking for some way to make a warning klaxon or similar sound alarm for when my rocket silos open their doors...

Anyone have any suggestions? IC2 had something like this, but isn't in this pack. I tried searching for alarm, klaxon, sound, etc. to no avail.

i don't think it was in ic2, I believe it was in IC2 nuclear control. however, you could try a note block hooked up to a clock that's active on rs signal.

or if you're programming savvy, opencomputers and note blocks...

Note block is a good idea, thanks!
