Hauppauge FD

[Rudy3145]

Does Hauppauge FD use their fireground or their Tac-1 for primary fire ground comms?

thanks in advance

I think I have some saved audio from them in @ProScan and will see when I get home? Do you listen to Hauppauge regularly? What are those annoying sounds the transmit over and over everyday?

 

[dave3825]

Only thing I have them using is 478.5875 Hauppauge Command/Ops but I am not that close so if the other freqs are simplex, I am too far to hear. I will leave connected to rooftop antenna and see what I get.

thank you

Not sure about simplex but I can confirm I’ve heard them using the 478.200 repeated FG channel for incidents in the industrial complex area.

I get 478.5875 pretty good and never hear anything on 478.2. Can you confirm 051 dpl?

 

[dave3825]

Last 2 days has mostly been 478.5875. I did hear radio repair doing testing yesterday briefly.

478.5875 DCS031 paging & response/command
478.2 DPL051 fire-ground repeated
481.2 DPL051 fire-ground simplex
458.0375 DPL031 is listed as "TAC 1"

I think they use 481.2 simplex for fire-ground but wasn't sure if they used that TAC 1 frequency as a simplex fire-ground

Does anyone know what exactly these do? Hear them throughout the day.

I didn't listen but I have a feeling you're talking about what sounds like repeater noises, they have numerous sirens set up throughout the district and the noise means the siren is checking in with the repeater, that's how it was explained to me

That is a data burst. Could be fore MDT's or their siren activation. I'm not familiar with their department so I don't know for sure.

Have a listen. Its annoying and that's just one of them. Sometimes there 15 to 20 of them that span 5 minutes straight. Also Hauppauge is the only dept. I hear this on.

I listened to your recording and it sounds like a Motorola Intrac 2000 siren control system, a sound I haven't heard for many years. Surprised it is still in use or maybe it is a similar system. If it is on a channel shared with voice there would normal be no PL on the Intrac transmissions so voice users don't hear it. It transmits periodically to insure the siren is alive and well.

I have proscan set to record each transmission in a new row and it shows a DCS of 031 when that sound goes off on their ops/command channel.

It sounds like they are running the Intrac, or whatever it is, through the repeater so the remotes (sirens?) are just like other units.

In an ideal installation, the Intrac controller is hard wired to the repeater TX and RX so the Intrac master keys the repeater with no PL and the remotes on the repeater input do not transmit PL so the repeater does not key up but the RX audio goes right to the Intrac controller.

Extremely late reply but that is an FSK data transmission for the outdoor warning sirens in Happauge
