Same here. Images don't load

I'm seeing the images just fine

It may be due to them being PNG format, maybe some browsers don't like it. I'll try converting to JPG format.

I could not see them the first day but I see them just fine now. Very nice pictures!!!

It was due to my personal web space not being https, and some browsers default to require all connections to be https nowadays. SSL certificate purchased, certification 'authorities' got their money, now you can see the photos.

It's amazing how far sirens have come in innovation. It takes far less power to run a T-135DC than that old P-50.

I wouldn't mind having a P-50 in my back yard though - I could get a big enough genset to run it =D

You'd need a genset the size of a car to run one of these. They pull 900 amps at startup on 208 volt 3 phase. On 240 3 phase, it's around 500 amps on startup. On 480 3 phase, it's much less at 200 amps to start the siren. That 50 hp motor is a pig and requires so much energy to start.

Good to know! I'm looking on GovPlanet for 480V gensets and I have no clue if they can put out 200 amps to start the thing. There are some really beefy civilian units on there. If I were ever serious about getting one of these 50-horse units I'd be making some phone calls and searching some manuals. It seems the military units top out at 416V, but I can't really think of anything the military has that would need more than 240VAC to run outside of some portable A/C units, maybe portable MRI machines for a field hospital?

Either way I know I'd need at least a 5-ton to tow a genset that size - maybe I can finally talk my wife into letting me buy a wrecker

It sure makes the T-128 and T-135 attractive. They're so energy-efficient in comparison, and the battery backup is really nice. I wouldn't mind having to run a siren on a bank of batteries. I wish I could do that with my Model 5!

According to the manual the P50 weighs 2000 pounds. So you will need a crane to move the siren at a minimum.

Yes, the T-128 and T-135 are far more energy efficient. They can run on a 15 amp 120/240 service if the siren's entirely DC according to the manual. The AC version requires a 50 Amp 120/240 service.

Here's the P-50 manual for reference if you need it.

That's for the crated weight. Actual weight is more like 900 lbs.

With powering one of these, you'd need a BIG genset. We're talking at least a 200kW 480VAC 3-PH generator.
