help needed - FAI Security Guard setup

[Bazza <barry_ryder_nospam@xxxxxxxxxxx>]

G'day

I have a wireless security (and I use the term loosely) system that FAI
sold me a few years back (for a laughably inflated price). The battery
in the main unit has gone flat, I've sourced a replacement, but it
appears the unit also needs to be setup again (or reprogrammed).

Does anyone have any clues, or can offer any help? If you have a
programming sheet for these, or can point me at a website where I might
ask, I'd be grateful.

I'm fairly sure FAI called the unit a Security Guard II, here in
Australia. ("pile of steaming arsevomit" must already be in use?)
On the PCB it says it's a Ness SG3. On the surface-mount it says Ness
SF3. It's the one that talks to you and has a 6 digit led display.

I should probably just replace the thing, but it cost so much I'm
determined to keep it in service somehow/somewhere, even if I do.
Anyway, if you can help, thanks in advance. If you want to reply to me
(or grab me on msn), just drop the _nospam from my email.
