I have always ran two sirens one for back up in case my main does not work but i have ran both at the same time because people just don't pull over anymore.i have the system 9000 siren threw my astro spectra radio and just got a nice whelen 295sl100 siren i was thinking of running both speakers threw the whelen but like running two sirens.

Of course, nothing's like having a big Q or Super Chief to begin with, along with an electronic. Odessa Fire is now using Eagle sirens along with Whelen electronics and the big train-sized airhorns. Talk about something that will hurt your ears. Years ago when I ran just a Q on our ambulance, I followed my friend who had the ambulance service in Clovis, NM back to Lubbock. They had a transfer patinet, and I followed them back so we could meet for dinner after their run. They weren't running "hot", and of course I wasn't either. But going into the small town of Muleshoe, TX, the guy called me on the C.B. and told me to light up my rig and stay with him, that the lady's pain shot had already worn off and they were going to go code the rest of the way. So I obliged, and ran no siren. About halfway thru town the guy hollers, "Hey, Skip. please roll your Q over, these idiots won't move over." I obliged, a cars six blocks down pulled over. When we got to Lubbock and his patient was tucked away in the hospital, the guy burst out laughing. He had to tell me that when I rolled the Q over, the little old lady who had been moaning and groaning sat straight up on the gurney and said, "What in hell is that?" Guess it worked! :yes:

Whelen makes a nice dual siren thats a remote flush mount that you can program to run a numerous different tones with the mechanical tone. i dont know the model number but i had one for a little while really liked it...and our ambulance's had a couple of them.

WHELEN HFSC9 is the one you are talking about

I run a Carson SA-441M MagForce Mechanical Siren through two 100W Dynamax speakers as my primary and use the Powercall single-tone toggle switch model through a third Dynamax for the "electronic" sound. It's very effective and the two tones, being so diverse, compliment one another nicely.

Those things are junk, they have the worst tones I've ever heard...

There are tons of other sirens out there that have the "Powercall" tones that also have much better sounding regular tones...

I just discovered thru another thread that the Whelen Gamma has the Powercall sound. Much cheaper than the rest, too.

Just saying what we've seen up here. Two tones seem to confuse drivers as they're waiting for a second vehicle to come by. My fear is if they get used to one vehicle with 2 tones, then when 2 vehicles (each running 1 tone) come into an intersection, the drivers won't know to look for the 2nd emergency vehicle.

Maybe I'm old school, but we were always taught that if you have multiple vehicles responding, the first should run an active tone and the 2nd should run a less active tone - but whatever the tones, make them *different* so people know that 2 vehicles are coming. The dual-tones kind of defeats that.

I missed this post at first. We learned around here almost 40 years ago that if you run units back to back, stay close to each other. Even with both units running their sirens, not all motorists are paying attention. In 1972 in Odessa, a police car was escorting an ambulance from the small town of Iraan, TX to the hospital. They were coming in with a young guy who had been in a rollover well southeast of Iraan, and their small hospital couldn't handle the head injury. Because of the nature of the injuries and the length of the journey, the ambulance had requested the escort, which was fairly common back then. At one busy intersection the police car made it thru the intersection, but the ambulance was hit on the right front fender. The other driver was busy watching the cop and never saw the ambulance. In Lubbock when I lived there, one night the units from Station 6 at 34th and Indiana were backing up Central on a structure fire just east of the Texas Tech campus. That brought Station 6: Batt. Chief, Engine, Booster north on Indiana to 19th St. and east on 19th. Two blocks east at Flint, the Batt. Chief and the Booster made it thru the intersection but Engine 6 got hit. A passenger in the car that hit the fire truck was DOS. The driver of the car told police that he had been watching the Batt. Chief and the Booster and never saw the engine coming. Now how in hell do you miss something as big as a Ward-LaFrance pumper? When our standby ambulance service first began we always ended up with an escort when we got into town; and for a long time couldn't figure out why. Turns out that the owners of the race track had been misinformed that we had to have an escort to run code if we came in. On one of our early runs with an escort I had stayed about a 1/2 block behind the cop. We had been told back then that that was a safe following distance while running "hot". After we concluded our run and had taken the patient in and had come back out. The cop was waiting for us. Turns out to be someone I knew and he was all over me for lagging back. His words were that if we were escorted again to stay on the cop's bumper, so we did from then on, until we learned that we didn't have to have an escort, so we were on our own!
