What Wired System

Hi All,

Its been a while since my last post mainly due to moving to Australia nearly 3 years ago...

Anyway what I would like to know is the following...

We live on the East Coast, and the temp can reach 35ish, and it gets really humid! we have just moved house and there is an existing (ancient) alarm installed, which I want to replace. is there a specific PIR that i should use for the higher temps and humidity? or would the kind of temprature I'm talking about here fall into the normall range of any standard PIR? also I would want a pet pir if that would make a difference to suggestions.

The last alarm I fitted was a Gardtec 580 panel and RKP, CQR ultima sounder, cant remember what PIR's I used... would anyone have any upgrade suggestions to what I installed? as it was about 4 years ago!

Any advise would be greatly appreciated.

thanks

Gary

Not sure if the heat would make much difference to the electronics but I guess the ambient temperature would an effect on how the PIR would work

I once had an extremely interesting convo with optex about humidity and detectors. id say give their tech support a buzz, they really know their stuff

These are specifically designed for conservatories so should work well in hot/humid temperatures

Any pir will struggle with close to body temp IMO.

In the uk I'd go for a dt, but I'm not sure that is right for you.

I'd prefer to use local knowledge

Providing the sensor has temperature compensation it will compensate for an increase in ambient temperature and still be able to detect movement, this only really becomes an issue in extreme temperatures where the background temperature rises to 50+ deg, with external temperatures at 35 deg certain rooms could well exceed the limits of the device. As mentioned above speak with some well known manufacturers and gain advice, local knowledge is crucial to avoifd false activations, or even worse in these circumstances the potential for missed activations.

Hi Guys,

Thanks for the replys, going to email a few manufacturers and see what they say, local knowledge is a bit thin on the ground here... as most are promoting wireless systems.

Will keep you updated

Anyone have any views on the upgrade options?

Thanks

I thought OZ regs did not allow DiY alarm systems, licenced Cos & licenced Engs, might be wrong though.

Someone told me I was ignorant and apathetic, I don't know what that means, nor do I care.
