anyone ever post this video? What siren is this? Thought it may have been electric but has a long wind down.

Ive never really been up the street (about 5 bloocks) to hear it so i dont know how long it really does take to wind down.douro20 wrote:Federal model 5 sirens have a very heavy cast-iron rotor which contributes to its very long wind-down; the one we have in town takes about three and a half minutes to fully coast down.
