Gday,
Just a question
What siren (wail, yelp or mix) do people use and where.
We use mix except when coming up to a busy intersection where we switch to yelp.
What are the thoughts of others?
Depending on the appliance Camo wail for long straights and mix or yelp for intersections and heavy traffic.......and air horns for ones that cant hear :evil:
mix and yelp give me the shits, so they are only used at intersections, wail is what we use for straights/long periods, and then theres also the london siren if things get boring...
air horns are great for giving slow traffic the right idea.
Yeah, we have people that love to set the siren on mix and leave it there, but most other people who have half a brain use yelp for intersections/blind corners on narrow roads, and wail for the rest. Then you've got the electronic horn for intersections or stubborn drivers. As a last resort if you are bored there is still the Hi-Lo on one appliance.
jeeze you guys have obviously got the siren control somewhere you can reach it then! On our 24 the on/off knob is on the lower dash but the one that varies the tone is behind the centre front seat (single cab) and you've got no hope of operating it while driving.
yeah same but the person in the passenger seat can operate it.
Our refurbished appliance has the yelp,wail and mix siren control box but its right in the middle of the 2 seats so only the radio operator can use it
The first emergency call our refurbished appliance responded to which happened to be that scrub fire out at Wandilo we had the siren on mix :lol: and it was really wicked cause it was a big change from our old siren box which just had yelp and wail
We use mixed, we used to change it if a vehicle would not get out of our way but our Capitan has said ours is to stay on mixed if they can not hear that too bad. So when he is not there we keep changing it on traffic conditions. :-D

Dave you can get a relay board and retrofit to the siren so the driver can change the tone by hitting the horn button :-D
mattb will know the source for it as Morphett Vale did it to their 24 :wink:
Yeah all of our appliances have the remote switching facility on the horn, works well and means that the driver is in full control.
Give those crazy lads at Emergency Safety Systems (ESS) a call, they should be able to sort you out.
ta, will talk to the captain about it as he's keen on a few other small mods to improve usability of the appliance.

How is leaving the siren on mix < half brained compared with people who change it from one to the other? Wouldn't the < half brained people be the ones who change it all the time rather than setting and forgetting it? ;)
Just suggesting that the sirens have multiple sounds for different uses, and it defeats the point of having the different sounds if people set it on one and leave it.
Doesn't it defeat the purpose of changing the sounds if all the sounds are operating at once? (which is what mix does - wail and yelp together - hence not needing to change when approaching an intersection...)
Isn't the point of yelp to create an obviously distracting and different sound around intersection to attract the attention of motorists? Thats atleast how most every other emergency service in South Australia and the world use their sirens. If you leave it on mix, then, yes, it does have both wail and yelp at the same time but there is nothing to change it to that is different. Plus Mix operates a highp itched tone which I find a bit quieter and harder to hear.
Actually, the the distinction is more to do with sound waves, and how far they travel... Yelp travels shorter, but is better at getting attention (hence used at short range spots like intersections) and wail travels further, (hence why it is used on long straights)...
Not quite, but if it makes noise and gets people out of the way, then at the end of the day its good.
hmmm.... well i rekon mixing it up a bit is good...
you use wail... hit an intersection go to yelp, then back to wail....
>?
hitting yelp is meant to let the public know that your entering/approachign an intersection.

Personally it drives me nuts to leave it on for an entire trip anyway....
using a single tone gets on the crews nerves after a while too.
Hyperyelp/ Hyperlow and Air/Electronic Horn through intersections, vary between wail and yelp through traffic / longer periods without intersections...

What truck is this on?
Would it be possible to get a sound file of it?
Found the following for you...
http://www.fedsig.com/multimedia/sirens/index.php?id=108
HYPERYELP = 'Priority' tone
If you really want to move traffic, have a listen to the ' Scan ' tone also. - The electronic airhorns are a little dull, true airhorns break peoples concentration / tunnel vision when driving and really make the ears perk up.

For another version of hyperyelp - listen to 'Priority' tone on this link also..
On older appliances with 2 speakers mix is a bit softer coz they put one tone through each speaker.
On newer trucks with 1 speaker mix is as loud as the other tones .
As of this year no new CFS appliances will have mix as it is not a recognised siren tone, they will all have the code 3 siren in the attached link.

Tillerman, do you know if appliances will come with air horns and the PA system?
Thank god, finally a proper siren. It'll be good to have the old Hi-Lo back again.
CFS_Firey, I would imagine all of the appliances would come with the PA system and the electronic horns at least, as they are built into the siren controls.
Correct 2090, the siren has an electronic airhorn and P.A.
The appliances will also have LED mini bars to allow for the height restrants.
2090, I asked because it says "PA operation available" indicating its not necessarily standard, and the photo clearly shows the PA mic and volume control attached to the main controller, not the button panel...

Oops i think we replied at the same time.
CFS have to have a PA so it will be on there, the volume is set at maximum as with the last lot of 34's and 34p's. Also the PA can be used at any time and will override the siren tone.
OK, cool... How about the radio being hooked up? (Or is that just wishful thinking...?)
Can be done but CFS won't be doing it, all you need to do is split the GRN speaker cable into the siren box and then when you arrive flick the siren to the radio position and the GRN will go through your siren speaker so that everyone around the truck can hear it.
Are you aware if the siren control has any additional tones, activated by the manual button when on a standard tone?
Thanks.
When on wail and manuel is pressed you get yelp, when on yelp and manuel is pressed you get HyperYelp and when on Hi-lo and manuel is pressed you get HyperLow.
Also when siren is in standby mode and manuel is pressed you get wail that goes to the highest pitch and stays there till you take your finger off (the same as all manuel buttons on appliances now).
Thanks mate. Definately a step forward.. Although, it all comes down to the user.. :wink:
