Its a domestic property, so IR beams would look a bit naff?? The PIR's you guys suggest, are they large and monster looking??

FX-50 SQ is a great PIR - as Kipper saya, and not too bulky or obtrusive. Larger than an RX-40 (but similar shape) , smaller than a Sequad. Don't know if that helps...

Had a look at the Fx-50 SQ on a web site, no mention of its IP rating etc?

According to the Optex spec-sheet, the FX-50 will work in humidity of up to 95%.

See:Optex website for confirmation.

Don't forget also that in extreme humidity, the water can also penetrate the cable insulation - a particular problem with ID systems. Keep your cable runs in the pool area as short as possible, and if possible, you may find it better to use some sort of screened cable, just to keep the moisture out. Obviously if you have a problem with moisture in the cable, you won't discover it for a few years...

Yep we always use screened for id, better safe than sorry

They have paid £15, 000 for a Dehumidifier Calorex machine, and the company reckon you wont get any water droplets on the windows or the skylight, they have written this in the GUARANTEE!!! Its also supposed to put the heat from the condensation it collects back into the boiler circuit to prevent waste

Lets wait and see
