Run a 16 ohm speaker from the speaker output on the keypad (if you've got the LCDL type, if you haven't I would recommend as the screen is much better on these), it'll make a loud enough racket in alarm condition and as and addition, you'll get louder entry/exit tones to boot. Failing that, I had to run an internal speaker from the spare pairs on a PIR on my own system which was first fixed by the house builders, not ideal but I've never had an issue with it to be fair.
