Scantronic Rfx Wireless Expander - Advice On Placement

[kuchars22]

Hi, I've attached a profile plan view of my property. I have wired PIRs and contacts and used wireless where wired is not an option. I

have the 9750 control panel with an RFX wireless expander. The question is, where is it ideal to place the RFX expander? I've got a number of RF PIRs and one contact in the home, with a futher 2 more RF PIRs in the garden, one in the garage and one in the shed. The shed PIR is the furthest from the home at 19m. I'm considering whether to put the expander in the loft, towards the rear of the house, or downstairs up on wall as far back as I can in the utility room as close to the garden as possible (can't place it in the kitchen).

So I'm wondering if there are any disadvantages in putting it in the loft? Will I be able to get the range from high up? Will there be any interfence from the TV aeriel and distribution kit which is also in the loft, or from the pitched, slated roof? And if placed downstairs at ceiling level, how well does it recieve RF signals through a 2 skinned breeze blocked wall?

I haven't had a radio survey done either.

Comments appreciated

Thanks

Without the advantage of a site or radio survey my first choice would be in the loft giving more free space between it and the garden units.

Dead centre - middle of the garage?

[kuchars22]

That'll mean wiring externally to the garage. Would want to avoid that.

Higher is better.

Higher is better.

Wireless routers radiate the signal like a bubble, with the router in the middle of the bubble. They say position the router in the middle of the house so the signal radiates all around it. I can see putting the RFX higher up can help with similar principles in mind. Any other comments on this?
