Connecting a Reson8 bell box to an Optima Alarm panel 8EP396A with 4 core cable.

I am replacing an existing old bell box with a Reson 8 bell box 8EP420. My alarm panel is a Optima G4. They are connected via a 4 core cable.
The existing panel wiring is as follows:
Panel Bell box
Strobe+ (no connection)
A link between T and A
Strobe- (yellow)
A (blk) SCB
D (red)Bell+
B (blue) Bell-

The Reson8 install guide only shows a 5 wire system:

Panel Bell box
Strobe- Stb-
B (Bell-) Trig-
A- Hold off -
D (Bell+) Hold off +
T- Rtn -

I cant work out how I should wire the Reson8 from this.

Any Alarm installers able to offer advice?
 
 

I couldn't quite understand above 

 

But you can wire the -strobe and -bell together to the -bell on the panel 

Agreed if you only have 4c then ho pos, beg and tr. Then use the 4th for combined bell and strobe trigger
