No need to shush, it appears the website is down so we can safely guess that cooper and Professor B are sharing a spot under some freeway in Germany right about now

Folks,

Update on the drama with my system. The company has agreed to replace the DSC pirs with Bosch Tritech units (They also call them blue line). The bad news ... they cost a lot more. Even if they are not charging me labour, its still working out to an additional AUD$660, thats 6 units in total. As expected, the family are not supporting me on this one. Yes, I did complain and kick up a fuss, but they are standing firm on the fact that they are only charging me the difference in the cost of my originals and the new units. What I can't figure out is, pirs in general seem to cost a lot more here in Aus than say in the US or UK. I took a look at Bass's online store ... for 6 units, without shipping, it's still only a third of what I am spending here. I have called around a few other local companies, and they are all charging way above US rates, in fact the cost I got from my installer is cheap ... hmmm, maybe I should get them shipped from the US!!

That may seem like a good idea. The only thing is that you'll have to find a friendly local company to install them. You can try some of the online stores here:

either you have a HUGE house or you have too many motion sensors. eliminate all but a few 'critical' ones and live happily ever after.

I've said this before, but it bears repeating:

Don't automatically assume that all of your problems will be solved by installing dual technology detectors. Detector placement is extremely important for reliable performance, and dual technology is not a substitute for good installation practices.

For example, I can think of a place that suddenly had LOTS of false alarms one night, even though dual tech sensors were in use. No previous problems. Turned out they had just gotten a new space heater (a big one, with a fan that blew hot air directly at the detector every twenty seconds or so). You could stand there and watch the unit trip when the hot air hit it! That's an extreme case, and the fan was blowing very hard, even though it was ten feet away.

The point being, first install the detectors in the proper locations. Dual technology is a good idea, but it's not a cure-all.

What do you mean? My dual techs chased out the ghosts haunt>

indeed. the quality of the technician is quite often more critical than the quality of the technology.

They're actually running a fishing guide service in the Amazon. They started out by selling "boat anchors".

Serves them right!

New species of fish has been developed.

Called "Gagging Pirana".

They are now vegitarians. No sharp teeth, only large molars.

My spell checur spells "pirana", piranha. The "ha" at the end is very important. It's the sound you hear as they swim away.

Now that's really strange.

I hardly ever use a spell cheker(ur)(a)(or)(um) but on this word I did. It shows pirana and down lower(ur) it shows piranha, (which I missed) Upon your note, I looked up pirana in the dictionary and there's no listing.

So now I wonder(ur) why pirana is in the spell checker(ur)(a)(or)(um), at all.

Maybe they just want to make bad spellers feel good.

I'm not usually a bad speller. I did spell "Connecticut" wrong once. And I'm always tempted to put the "r" in words like "wash" and "Washington". :-)

I'm always tend to think of BS when I think of Washington.

That is common practice in the alarm industry, Eddy. I get a lot of flak here for offering hardware at prices slightly above installer cost. You can order Bosch sensors online from a number of sources, including

but we don't accept credit card orders unless the card has a US address. This cuts down on fraud which is a major problem for online vendors. We do ship overseas though.
