Ive used the ion a few times and they do work well but for how long?

And how secure are they?

Thats whats going through my mind

The rkp is used on the menvier i series panels now too, with no zones on it!!!

Ok fair enough.

I know scanny boasted long range with their kit, saying free air was reliable to something like 4 kilometers iirc.

Are you saying the transmission of rf is like friedland or the encription side of it?

 

Really? It's just standard licence-exempt RF stuff, so limited in power. It uses 2-FSK modulation, so you can't get the higher power afforded when using FHSS.

 

The panel has a transceiver in it so it can send and receive, and the fobs do as well. But the detectors I have seen have transmitters only so are one way. Major limitation really. 

 

There doesn't appear to be any encryption.

 

So, it meets the standard, but it feels like that is all it does.

there is a new rf standard about to be published for draft comment I believe.

I will double check with the boss im sure it was 4. Something k.

Apparently tested accross a large beach somewhere.

Who knows really though?

Only got their word for it.

So afayk the panel is 2 way but detectors 1 way?

Im just popping to all my ion sites

so the important bits are 1 way?

I think 868MHz is limited to 10mW. Even line-of-sight, you can't get more than 100m or so. I think one of the Honeywell systems (Domonial or something?) claimed km but there was no way it could do that.

so the important bits are 1 way?

 

The single door contact I have is, yes. I don't know if they have different detectors that are better than one another?

Sorry we sell the scanny on warehouse, never used one though.

It's clearly had more development than Friedland gear. The panel has a lot more flexibility.

What I don't understand is why pretty much every component of the Scantronic gear has a different RF front end and microprocessor. It's like 5 different design teams worked on it. Must be a pain for them.

possibly using some stuff from the menvier range when they were separate?

Intergrating again?

Burnt their fingers last time they started swapping.
