connecting speech dialer

Hi: anyone advise please, Going to connect an Informa Speech dialer to my Scantronic 9651 panel
we work 5 minutes from home so its just a little extra security.
It can only be connected as (Bells only ) and in the manual I've got
these connections
Comtrol Panel Informa
Bell B- ------------IP1
IP2
IP3
SET ---------------INH

and in the Panel I've got

OP1 OP2 OP3 TR + -
spkr
Manual says connect on bells only to bell output in this case that would be OP1 were is the 2nd core of the dialer connected to ??????? or does it not matter.

Thanks for any advise

Your unit looks like it requires a switched -ve to operate it. The +ve will be the other side of the dialler connection, this should be the aux 12v +ve or the 12v +ve to the PIRS etc.. The other connection you mention looks like an inhibit line ignore it.

If your bell output does not provide a switched -ve on alarm then you will need to install a relay on the bell output and then use that to provide the switched -ve.
PS do not program the speech dialler for 999 as it is illegal.
