The Siren Board

Alert, Attack, Hi Lo, Pulse, Alternalte Wail, Whoop Are what I can think of off the top of my head.

From the SiraTone EOWS* manual:

Oldiesmann wrote:The cabinet had space for 7 tone modules, but only shipped with 6 (unless you ordered a 7th tone). If you didn't order a 7th tone, you'd just slide the Whoop module in the empty space - otherwise you'd just remove one of the other tone modules and put the Whoop one in its place.

Does anyone have soundclips of all the alternate tones mentioned in the manual? I've heard Westminster Chimes, and found soundbites of "Yelp" and "Yeow" in another post, but I'm wondering what some of the others sounded like.

Thanks for clarifying that. Where are the other soundbites? I would be interested to hear those two. The relevant section from the manual states:

I've read that 1003 Tbolts can do the same tones as the EOWS, but have only heard Alert, Attack, and Hi/Lo. The others, I've only heard as synthesized - would love to hear a Tbolt do the others!

We know of course that the 1003 was originally produced with the capabilities of Alert, Attack, alternating steady, alternate wail, pulsed steady, and pulsed wail.
It would be pretty easy for a 1003 to do Whoop. All it would have to do is start up the chopper for a second or two, close the solenoids and de-energize the chopper, open the solenoids, start up the chopper, etc. (all with the rotator and blower running the whole time). It would take a controller that is more advanced than the AR/AF timers, but would be able to do it with modern technology.
I believe the yeow signal for a 1003 would just be the opposite of how I explained the Whoop signal.
I think horn would just be a more extended version of the pulsed signal.
Slow whoop could be accomplished by just using my previously mentioned whoop procedure but with only a small voltage to the chopper, thus increasing the amount of time it would take for the chopper to wind up. The solenoids would also have to repeat the required cycle less quickly in order to give the chopper time to do this cycle properly.
You could theoretically have a t-bolt produce westminster chimes by having the chopper run at different speeds at different times and opening the solenoids as necessary to emit the proper tone. It wouldn't be timely/efficient like it would be on an electronic siren, but could be done.

I made this video friday night.

I used 2 Whelen 2700 400 Watt Speakers.
I did find out that the alternating tone does come out of each output.
So I can use only 1 speaker insted of two.
By this time, My batteries were either getting low or one post is going bad.

I had a Federal sales brochure from 30 years ago stating the SiraTone had the same sound as the Thunderbolt. Too bad I lost it.

This might be a dumb question, but is that control unit from Shelden park's 612?

No it is not. I have a photo of the ID tag on the battery cabinet from the Sheldon one. The Serial Number is like 8 digits long (and hard to read), Mine is a 5 digit serial number

Incorrect.

The circuit board is set up with 6 tones and has a slot for adding tone card for the 7th tone. It looks like the same ones they use in the SelecTones.

Here are more pic's of the internals.

Before when in the video above, the siren would cut off randomly.
I read the manual 3 times, and noted the SiraLock feature.
So I unplugged the radio, made a jumper for the SiraLock.
And now it runs non stop. I had Alternating Wail go for 8 mins till I hit cancel.

So On to the pic's.
These may be big for some.

The System 7000 series (The 7026 which uses the 1003's head) came with a controller that did all 6 primary EOWS signal. Pretty much a more sophisticated version of the AF-Timer.
