DSC ESN Conversion

Sorry for the top post...I was trying to email this to someone who ask this very same question a few weeks back.

Too bad they couldn't make a dual-frequency receiver

There is the PC5320...

(may need to login to view)

Not exactly what you're looking for, but it looks like it'll at least save you from replacing all the old 900 Mhz devices.

You can't mix and match which is what I imagine most people would want. The main advantage to the 5320 is expanding coverage

Are you sure? The website says you can use 433 and 900 on the module.

The spec sheet and installer guide says each receiver has to be the same frequency and version, maximum 4 receivers. You can use 433 or

900 but not both at the same time which I would guess most people want

We have one in the office but I've never played with it or seen one installed. Just a random part sitting on the shelf that came from our other office.

It sounds to me like it'll either expand coverage or do 900/433. Also, the below link also mentions an 868 frequency... I've never heard of that one. I guess it could perform both functions if you have 900 Mhz devices at one end of the building and 433 Mhz at the other end.

In the installation instructions

, look at installation step 6. There are two options: expanding coverage or multiplexing frequencies. Although with option B there are some strange restrictions for DLS.

Perhaps there's a reason this part has never been heard of?

It appears that the v1.0 manual they list is for the Euro market since

868 is used there and that model can do dual frequency, both North American manuals listed specifically state it can't and all receivers have to be identical

Which is odd

I had a rep tell me once that you could use both freq's with the 5320, but it was a pain to program. you had to un-hook the 433 and program all the

900's then rewire the 433 and program all it's sensors. i have not had an occsion to try this, but i was asking because i have a few older systems out there with 900mhz sensors still on them.

Looking at the euro documentation it does like it hinders download programming

They also dont tell you it will only supervise one of the 2 receivers.
