Hello Folks, I am finishing up a station alerting install this week for a local station. The last part of the system is to remove the old Federal timer and tie the siren contactor into the new logic controller that runs the entire system. Not generally a big deal, but I am looking for some info on t...

Yes sir. At East Lansdowne we have an sth10. Lansdowne has a modulator that is used fore fire calls. They used to have an sth10. Its still mounted on top of the borough hall but no longer used. The sth10 at collingdale 2 was just turned back on earlier this year. Does not sound good... sounds very u...

Im a Captain at East Lansdowne Fire Co and also run at Drexel Hill Fire Co. This siren went to collingdale fire co number one. I was helping another company out. I do pager/radio work and station alerting systems on the side down here.

I just installed this siren on Saturday.... Got it used on Govdeals. Painted it up and cleaned it up. Installed for the folks over at collingdale fire co #1 in delaware county pa. http://youtu.be/mPlV4p6S0Z0

Where are you located?

I'm in Delaware County Pa. Just outside of Philadelphia.

Good call on the steering wheel puller. I need to see if I can find one. The key is badly rusted on the shaft. I did actually try heating the chopper but not the shaft itself . I may have to give that a try also. If I end up looking for a new or used motor or used sth10, any idea how much I'd be loo...

Understood.... it is a 3 phase siren. A local fire company may have a spare motor and I'm waiting to a hear back from them. I'm hoping I can get the chopper off without damaging anything. The motor is in very bad shape. A new motor might be the easiest route. Some damage was done to the bearing ring...
