Our alarm keeps beeping every now and again. The only way to stop is to start the alarm and turn off straight away. tried to find a manuel on the net with no luck

I've seen these (modern alarms) it's basically a DSC 600 and that manual is easily found.

The intermittent beeping is alerting you to a system fault and usually accompanied by a lit or winking "TROUBLE" led.

Usually pressing any key will silence the alert and the keypad will display a trouble message,have you read it???.
