Centracom Alert Tones

I was wondering what the tone duration and freq is for the Centracom Alert tones. I am mainly talking about the warmble like tones. Theres one that is momentary when you hold the alert button down. This rapidly flips between 2 different tones. The other one is the one that immiediatly follows the QCII tones. and it flips between two other tones a little bit faster.

I do know the other 2 alert tones are 1000 Hz with one being as long as you hold it down and the other intermitent ex beep beep beep.

Does anyone know?

Alert 1 - Steady tone for lenght held
Alert 2 - High low for lenght held
Alert 3 - "Beeps" (Think CHiP's beep beep beep)

The one that is programmed with the QCII is normally labeled as "Plectron" or something similar. The exact tones vary by installation. In fact, we had two tone board sets in the same CCII console and the newer ones had a different freq set than the orignal ones. Not by much, but you can tell they were different.

Do a search in the fourms, I know someone a year ago or so posted the tone freqs

Yes, the hi low tones is what I am looking for. I did search and can't seem to locate it. I know in Anderson, SC and Spartanburg, SC the one right after QCII is the same sound. I do have wave files of each of the 2 sets I want. Just can't determine the freq and duration of the tones.

From the programming manual, "Alert_2 Generates 2 tones on selected channel (1500/800 Hz). Hope that helps. Sorry, it doesn't give the length of tones.

L.E.

Thanks!

That is definetly the right freq for both sets that I was looking for. I will repost the exact duration of the tones since i now have recordings of them both. I am using Cool Edit to figure it out. Thanks for verifying that the tones I was playing with were actually correct.

ALERT 2 - 1500HZ/900HZ 250MS/250MS

ALERT 3 - 1000 HZ 250MS ON, 250MS OFF

Alert Tones After QCII Page

On the subject of alert tones... the old Centracom 2 could be programmed to send one of the three alert tones after a QCII page was sent. We have Gold Elite consoles and I cannot seem to find where this is programmable. Our local fire agencies would like Alert 2 but I can't find how to add this to the page programming.

My understanding from the MSS guys is that its NOT the traditional Alert 1/2/3, but a preprogrammed "plectron" alert (hi/low's or whatevers).

The times that I have heard the actual alert 2/3's, it was done manually by the dispatcher after the QC was sent.

As a former Sr. Motorola Technician I can tell you that the tones are indeed 800 and1500 hz.
The Motorola Centracom Alert tones as per the Motorola manual are (The hi/lo) 800 hz / 1500 hz at .100 sec each
