Elmdene prima? Are they still decent to use?

Come on guys, I have been patient enough, I would just like to know your experience/ideas on this?, my question as above. thanks

If you can't be bothered reading back, my question is this for the final time without sounding like a broken record, Do slower tone type sounders naturally travel further than other sounders with fast rapid whoop types? even if they are both the same decibel rating and are mounted in the same place/area?, or it all weather dependent?.

thanks.

When I say "travel further" what I mean is do they have better sound distribution around a neighborhood or in open space?. thanks

I should have known better not to post questions during the summer, most are likely taking a break from this site. I will ask again when it gets busy,though I'm surprised that nearly 400 views on this post not one can answer but anyway,I will keep a regular lookout for any updates regarding my question.

I always liked the Toplok stainless steel bell (not the crappy plastic "Elegance" one) - it whooped AND wailed so it definitely wasn't a car alarm. I've never tried different bells on the same building to see which one can be heard farther away... If we want one to carry a distance, we'll use a Master Blaster or an Aritech (AS395, AS610...). Otherwise we stick to one make and get it printed (obviously, Pyronix Deltabells at the moment).

Sound travel is a strange one, I think its all to do with the frequency and probably the weather conditions will have some effect as well. You can have one bellbox that's ear piercing loud close the property but can barely be heard down the road, then you can have an other sounder that's not quite as loud but can be heard down the road, Generally alarm sounders range from 1 to 3hz, but unfortunately when you buy a bellbox it only tells you the db rating not the frequency, the tone of the siren may have some effect on how far it travels whether its fast or more of an ambulance warble type.

One thing I have noticed is the keypad entry/exit bleepers they can be heard from quite a distance away from a property, (at least on mine anyway) and they are only 80 odd decibels, nowhere near as loud as a bellbox but can be heard at almost the same distance as the bellbox which is rated around 115db?

I think its all to do with the frequency and the weather combined at least that's my take on it, I'm no expert, If someone can explain better then by all means.
