I've just fitted an alarm to my 'new' van a Suzuki Supercarry (Sooty's tour bus!). As it is rather basic, there are no door switches for the internal light, I need another way of making the alarm go off, so will need to get a microwave sensor to detect movement inside the van. Being as it is such a small van, would one centrally located sensor work, or should I get a couple, one at either end? Thanks Alan.
you would be best to add door switches, all those sensor things give trouble IME, a few door switches and some wire is far cheaper too
Most modern alarms have a voltage drop detection circuit.. This will trigger when the interior light comes on if a door is opened. If not you should be able to connect into one of the wires on the original door switches.
