Connect Alarm Hills R8 to Phone Line

Hi,

I have Hills R8 but not connected to the phone line as yet.

My plan is to connect it, so that I will be able to get a phone alert when specific user disarm the alarm & potentially config the alarm using DL900 software.

A) Connect the phone
Can you please confirm whether my steps are correct:
1. Connect active phone line to the Alarm panel using normal RJ11 cable
1a) Should I disconnect the power and backup battery beforehand?
1b) I have ADSL 2+ connection with filter, I suspect it won't be an issue (to connect active phone line to alarm unit)?
2. Enable feature 4, by adding the phone number
Segment 1: 15
Segment 2: 13 (to wait for 4 sec delays)
Segment 3 - 12: mobile phone number (eg: 0410 000 000)
Segment 13: 14 (end of the phone number)
3. Feature 6, change it to “Domestic Siren” (3)
4. Feature 9, segment 1, enable option 3 (open/close event report)
4a) Can I get report on specific user?
5. Feature 10, segment 1, to change the amount of dial attempts
6. Feature 16, segment 3, enable option 1 (enable opening and closing reports)
7. Feature 22, segment 3 & 4, configure as required
8. Feature 22, segment 4, switch off option 3 (to disable auto test calling)

B) Config the alarm using DL900 software
Questions:
B1) Where to download the software? I google'd it found nothing to be found
B2) Is the application acting as a dial-up modem, which creates an outgoing phone TO the alarm?
B3) I suspect I need to configure feature 12-15 prior running the 900DL software?
B4) Can I backup Hills R8 configurations beforehand?

Thanks heaps!
