Klaxon

I've got and older one of thier "Duplo" ones sitting about somewhere, at 126dB it's a lot louder. And you can fit a pulse relay to get that authentic American cop-car siren.....

coo.

I like the big monster ones. 145dB dual-frequency... now that's what you call an air-raid siren. They used to have one on the top of a tower in Lampeter which was used to summon the volunteer fire brigade. Now they all have bleepers, nowhere near so much fun.

Yeah, that one's got a 3-phase motor, you ain't gonna run that off a car battery....

Alex

Whip the motor off and clamp the business end onto the power take-off ;-)

Now there's a thought.....

Alex

Two of them beasties sitting under my bench waiting for the tuits to do summat real with them. Anyone got any bright ideas?

Possible rig up an air-con clutch to drive them off the crank shaft pulley? There might be a little bit of the equivalent of turbo lag as everything winds up, but it'd scare the bejesus out of pedestrians :)

Karen

You evil wench - that's sounding like a bloody good idea. ;-)

Not quite a klaxon, but my 101 now almost has a dukes of hazard air horn fitted :-)

(Thanks Martyn!)

Out of interest, how fast does the PTO turn ? Never having had one, I'm not sure where they extract power from the gear train.

Steve

It comes off the transfer box, you whack the box in neutral and the speed of the PTO is proportional to the engine speed, that's how I understand it works. I don't know how proportional though.

are you allowed that? I thought musical horns were restricted to pre-71 or something?

It's only a guess, but I reckon that as long as the official "press to alert pedestrians of presence" button activates the approved "pedestrian warning device" (the thing that usually just goes "meep" on a Series) then any number of interesting orchestral and maritime sound emitting devices can be fitted to the same button through an isolator. ....or through an independant large red knob marked "Brown Trousers".

Steve

Spot on, as long as you have a boring old normal horn as your 'primary' warning device, you could rig up the foghorn off the QE2 to any other button you so choose and it would go through a current MOT.

Ben

I've got a normal horn too.

I can't decide wether to leave my ambi siren on too or not! Its not like i can really ever use it, so the hazard horn will probably end up in its place, and using the siren button.

I had the 101 stored on a farm for a while. Me and the farmers son had great fun taking it in turns tearing round the fields with the siren on :)

I like mine, great for announcing your arrival at shows! Father played with my siren a lot this weekend.

They may not be used on the public highway. The ONLY caveat to this being if they're used as the alarm siren - which is obviously why I gave them to Tom... :-)

What have you got on the V5?

camper van.

I've read the discussions on the list in the past saying that i shouldnt legally have a siren, but i'm not planning on using it while driving on the road anyhow!
