Testing
All alarms are tested regularly. The crew is first warned that testing is beginning, then each alarm is sounded from every alarm location. Because the general quarters alarm lasts for several seconds, the collision alarm is sounded very briefly to override and cut it off. The many locations whence the collision alarm can be sounded are traditionally tested from stern to bow, beginning with the engine room lower level aft location sounding the alarm as briefly as possible, then each subsequent location sounding the alarm for a slightly longer period of time. By the time the torpedo room sounds the alarm, it is held on for several complete cycles of the siren.

Famous quotes containing the word testing:
“Now I see that going out into the testing ground of men it is the tongue and not the deed that wins the day.”
—Sophocles (497–406/5 B.C.)
“Bourbon’s the only drink. You can take all that champagne stuff and pour it down the English Channel. Well, why wait 80 years before you can drink the stuff? Great vineyards, huge barrels aging forever, poor little old monks running around testing it, just so some woman in Tulsa, Oklahoma can say it tickles her nose.”
—John Michael Hayes (b.1919)
“Today so much rebellion is aimless and demoralizing precisely because children have no values to challenge. Teenage rebellion is a testing process in which young people try out various values in order to make them their own. But during those years of trial, error, embarrassment, a child needs family standards to fall back on, reliable habits of thought and feeling that provide security and protection.”
—Neil Kurshan (20th century)
