Two high level alarm options
The Transit Courier is available with an optional perimeter alarm system, which is set off if the doors or bonnet are opened by force. A more sophisticated Thatcham Category 1 alarm system is also available. This automatically arms itself when you lock the vehicle and a powerful alarm sounds if triggered by forced entry, the vehicle being lifted, or if the motion sensors pick up any movement inside.
An extra, independent back-up alarm
A battery back-up sounder is an additional, secondary alarm system that comes with the Thatcham alarm option. This sounds a siren when the alarm is triggered and because it has its own built-in power source, will activate even if someone disconnects the main vehicle battery.
