Although honestly I prefer to keep my distance from stuff such as this because of drama, etc. I decided to give it a go.
Backstory:
Federal Signal won the bid for Gary, IN. As a result, in conjunction with the city planning dept., EMA, etc., they put together an elaborate yet effective siren system. The first phase was to install Model 2 sirens in the rough vicinity of fire stations. The reason for such is that the 2s, in addition to being storm sirens, are also in service as fire sirens. The next phase of the installations was the big stuff. This included the city's sirens and the airport crash system, as well as the siren owned by CSX. The final phase was the plant sirens to the north. These phases all happened within 10 months of each other. The abandoned CD sirens were left in place as a reminder of the days gone by, although within the city, it is all too apparent as one strolls down the street and sees all the decay around one. Back on topic, yes? The system is silently tested every Monday, Wednesday, and Friday at 12:00, and audibly tested the last Thursday of the month at 14:30. All sirens will sound without exception, unless of course one were to break or be out of service for whatever reason.
