This should get you started:

12v AUX = +H (holdoff+)

0V = -H (holdoff -)

OP1 = -R

OP2 = -ST

TR = RTN (tamper return)

For EOL termination (resistor),refer to your scanny book because if you utilise this mode then fit 2K2 risistor at TR on sounder.

The EOL resistors will come with the scanny panel so use the 2K's and 4K7's throughout your install.

If you need anymore help just ask.

Ps just use the terminals I've mentioned don't bother about the rest on the sounder :)

Just the normal run of the mill 7422 nowt to get excited about George.

If it had of been a rapier 6000 then that's defo worth keeping but them only reserved for adt prestigious installs.

What control panel is installed now gal g3??,hence the scantronic replacement?.

Thanks for your replies,i will take a look.I would like to keep the bell box as it looks quite modern in shape,better than the old classic style, alternating blue lights looks cool too.
