Could just be a test.
When I am in EWR
at the CO
terminal, there is a fire system test about 1/2 the time. The PANYNJ seem to love to test that thing.
I was in the CO
shower once when it went off. That alarm is WAY too loud for such a small room, but having no clothes on, all I could do was plug my ears to avoid hearing damage.
Of all the things to worry about... the Wookie has no pants.
