I'm a new owner of an RB5 and since I've had it the siren sounds every few days, sometimes at night sometimes in the day. It will stop as soon as I press the key fob but not sure why its keeps sounding?
Any ideas what the problem could be?

Jim you should have a PM.

Just for anyone else that maybe experiencing a similar problem, it is most likely due to incorrect adjustment of the ultrasonic sensors or a damaged bonnet switch. You can check which circuit last triggered the alarm, using the keypad and then observing the dashboard LED after entering the following sequence:

- Arm and then Disarm the system using a working Radio Key.
- Within 30 seconds of disarming, type into the keypad- *17856*38#
- Count the flashes from the Dashboard LED

1= ignition circuit,
2= door circuit,
4= boot circuit,
8= bonnet circuit
16= ultrasonics.

Should the problem be shown to be originating from the 'sonics, as I suspect, you should adjust them as follows:

- Arm and then Disarm the system using a working Radio Key.
- Within 30 seconds of disarming, type into the keypad- *17856*20*55##

This adjusts the sensitivity to the required level and should prevent further triggers, if not let me know.

When using the keypad always observe the following points:
- The PIN number should not be entered too quickly or too slowly - when a digit has been pressed the small LED built into the keypad will illuminate briefly as confirmation and only then should the next digit be entered.
- If an incorrect digit is pressed or the delay between entering digits exceeds10 seconds, then the LED above the keypad will flash rapidly and the PIN attempt should be abborted and started again after 30 seconds.
- Due to the small size of the keypad some users may find a rubber tipped pencil easier to use. DO NOT use the sharp tip of a ball point pen etc, or press excessively hard on the keypad as this will only damage the membrane and cause a digit to remain pressed, causing a continual incorrect PIN.
- The keypad allows only THREE PIN attempts and then will "Lock Up" if an incorrect number is entered a third time. This is a security feature to prevent random PIN attempts disarming the system.
