2010 Air Raid Siren Demo

[Travis]

The P-20 suffered from the same problem that some of the new sentrys have:

A battery cabinet the size of a Volkswagen hanging off the side of the pole.

Gotta love the truck tool boxes!

What year was the RM-130 made initially?

It was originally made in 1985. Let's not get into another argument about this, but I believe that it was original called the Performance Penetrator, then the PN20, then the RM-130. It was replaced in the ASC range by the Tempest T-128. Jim Biersach left a comment under the video:

I designed and built this model siren starting in 1985 as owner and president of Alerting Communicators of America (ACA). The company was sold to Gus"Sandy"Wirth Jr. in 1990 and he renamed it American Signal Co. I still have the design drawings in AutoCad, Solidworks and Anvil.

Wow, 1985. That is the same year I was born! I learned something new today. I wonder if this was the first mechanical siren to feature battery backup as well?

They are only running it at 50%.

1/3 actually, they are meant to run on 72 and it's running on 24. [/smartass]

So these are powered by 6 12v batteries? Was'nt aware they were 72 volts. Correction 33%

Just to be picky it's 33.33% (recurring)

They do say in the video it was meant to be run off 72 volts.

Oh yeah? Well to be even pickier, what if their battery isn't exactly 24 volts? It could be slightly higher or lower, as batteries often are.
