In my region, large sirens (air and electric) are every where, not just at each fire department. They go off every day at noon and six. You don't need a wrist mounted chronometer. One day near me the local electrical utility company was changing poles and had lopped off the top of one and shoved in another next to it. On the ground attached to the lopped off portion was an older rotary type electrical siren with 12 horns radiating outwards. The motor is 3 phase and is 11HP. My bro and I came back that night and "liberated" the siren by putting it in trunk of his car (mid 60's Ply.) The two of us could barely lift it. Its about 5.5 feet in diameter. Obviously the trunk could not be closed so it looked like there was a V-2 rocket engine strapped to the car. It sat for a few months and during July 4th weekend we wanted to make some noise without having fireworks. We tried hooking a 5hp lawnmower engine to it. Having no electric start, we pulled and pulled on the cord to get the heavy flywheel impeller going. The engine started firing and chugging. Only a few hundred RPM could be achieved with the inadequate engine producing a low buurrrrr but very loud. I have since properly wired it and blast it occaisonally.
