Aritech Ats Bell Connections

[Spaceman]

Hello Guys,

I have recently installed a ATS panel and spent some time playing around with the bell connections.

My question is whats the easiest way to connect the bell to a DGP. I used an output board for the bell trigger (-ve), hold of to aux supply and tamper return to relay then zone (resistored). Is there an easier way to get a standard bell to work without the relay, i.e can I connect the TR anywhere? do I require the additional relay board?

I used lots the CD's many years back and havent installed intruder for a few years.
