Federal Rumbler

[Abbott0489]

Anyone have any experience with the new Federal Rumbler system?
Is it worth the $500 dollar price tag?

[Weruj1]

I'll ask........................... ...what is it ?

[Fyrechicken]

Here's what it is, looks like an add-on to your current siren system. You turn it on at intersections and it copies what siren tone is being used but at a 75% reduced Freq. (It's more or less BIG BASS BOOST for your siren) one more item to draw power from your electrical system.

it seems that "Code 3" makes a product that does the same thing...

thanks ..................wonder if they work ..................who'd thunk that up?

[Abbott0489]

there is a video on youtube of a police car with it. you can hear it in the video (basically a very low frequency that copies the siren tone).

I also saw a news report of NYPD cars that now have it in a trial. people said that they would feel it, just like the base of a car. I have also had people tell me that it can shake car windows and rear view mirrors.

The system is supposed to be felt, and the target is distracted motorists that have loud music or AC blasting and can't hear a siren.

It sounds like a real nice new innovation, but my question would be if spending $500 dollars would be worth it? How much of a difference does it seem to make for other drivers?

Another link of news reports about various cities trying it out.
Includes Philly, Cleveland, and New York.

I listened to the video from the first one ................I sure could not hear a difference.

You cant get a rumbler for the truck, the powercall is on order!

I don't think you're supposed to hear the sound from the Rumbler as much as feel it, i.e. windows shaking and so forth. I haven't heard or felt one yet, but the Federal Signal guy showed one of our other salesmen, and he was impressed. I'm looking forward to experiencing one.

haha, i heard and am i relieved someone finally ordered it. from what people tell me this system can mimic the powercall just like a common wail, yelp, etc. when i heard about it a few weeks back i figured, how cool would it be for people to not only hear us, but feel us? haha

[Abbott0489]

oh, and Weruj1, as stated your aren't really supposed to hear it. go to this link....

The top interactive feature is the rumbler system. you can hear the lower frequency has it cycles. turn up the volume when you play with it... maybe i was just sub consciously thinking i felt it, but i could have sworn i was feeling a little something in my stomach listening to it kinda loud. then again... i could be nuts...

I've heard it and felt it. Having it installed as I type. It's something you really have to hear and feel in person to believe, the videos really do it no justice.

Imagine yourself in the midst of a half dozen industrial vacuum trucks and you'll have a better idea.

Not sure where the idea came from that it can't but truck mounted. Just not compatible with the EQ2B as far as I know.

It originally came about as part of a Florida Highway Patrol study into the effectiveness of emergency light and audible devices. I believe that that was back in like 04 or something, that’s the reason FHP changed from their traditional blue lighting to a red/blue combination. Even Whelen has a similar product out now. The new FHP setup is quite interesting using red/blue while responding and then either red or blue while parked controlled by a light sensor to detect whether its day or night. The FHP cars are red lights during the day and blue at night, it’s supposed to be much more effective and keep drunks from being sucked in at night by the lights. You can still find the study on the internet.

In order to emulate the sound of the Q-Siren®, the E-Q2B™ uses a digital
signal processor to generate signal containing a complex harmonic
structure. This complex harmonic structure makes the E-Q2B incompatible
with the Rumbler™ system.

From their literature.......

I have this installed in my patrol car.. In fact almost 75% of my agencies fleet has them installed. I can tell you that it does make a big difference when going lights/sirens to a call. Even pulling a vehicle over is easier. Its amazing that people cant see a multitude of LED lights in their mirrors and hear the regular siren going... but hit the button for the rumbler and their head amazingly comes out of their ***!!

It is true that it cannot be used with the EQ.. however it can be used with every other electronic siren, regardless of manufacturer... I'd love to hear it with a powercall myself

[Ledebuhr1]

anyone know why its not compatable with a E2Qb but it is with other sirens?

Also, is this speaker big? I would assume its big to get such a loud deep sound. Does it pull a lot of amps?

Here is a link to Federals Website, it is pictured on this page and you can see the size of the speaker, I believe they have specifications on that page.

Nope, it fits between the bumper and frame of a Crown Vic and Charger.

Does it pull a lot of amps?

Nope, it draws no more than the normal siren.
