@mfalkvidd - I thought as much, but the confirmation is reassuring. Thanks!

Placing a water leak detector on cotton
I need to place a water leak detector on a surface which is very uneven (a badly laid concrete underfloor). In its current condition, water running along the surface does not set off the sensor, however if I place the sensor on a small sheet of cotton wool, when a leak occurs the cotton wool absorbs the water and swells up enough to complete a circuit (therefore triggering the sensor) using the 2 metal probes on the underside of the device.
Obviously cotton is not conductive, and I understand that it has an ignition point of ~200c, however does this seem risky i.e. is there any chance that it could ignite somehow? It runs off a 3v battery, and the model is DY-SQ100B (I'm not posting a link to a retail site, as this may be viewed as spamming).
