Re: Thunderbolt siren info

Definitely read the manual for the siren and that'll answer many of your questions about operations and maintenance. They're freely available from multiple places across the internet :) You can convert single-phase to three-phase using an appropriately-sized variable-speed drive. I think the drive n...

Re: Sterling Identification Help

Another member here who's knowledgeable about the old Sterlings says the number at the end of the name indicates the year of manufacture, not a specific model. An M45 is a Model M built in 1945, for example.

Re: Question about Thunderbolt mounts.

The telephone pole would have the two bars (I'm not sure of the proper name for them), but that's where the rotator box would sit, with the blower pipe coming down the middle and connecting to the blower on the ground. So the siren head would still be mounted on the telephone pole, just not directl...

The thing is, there was no other siren there before the 2001.

Re: Uniquely Mounted Sirens Thread

That is a cell tower. Yes, that's extremely cursed! Apparently someone appreciated the old Sirex enough to put it on a structure built for a form of personal communication that was only a dream at the time it was manufactured 8-) Saw this 2001-SRNB in Albemarle, NC, I thought is was a bit weird for...
