Fitting and adjustment Pressure mat sensors should be fitted on a flat smooth surface and covered with a conventional floor covering such as carpet or lay flat rubberized matting. The covering is important to both protect the pressure mat sensor from damage and also to ensure there are no trip or slip hazards. Care should be taken not to stress the cable to pressure mat junction, this is especially important where long leads are fitted. If fitting a pressure pad to a chair seat the pad must be fitted to the flat rigid base of the seat, covered with a layer of protection, usually cushion foam or padding and then upholstered. As there are variables in foam thickness, density, upholstery material and fitting, customers will need to test for themselves the viability of a pressure pad in this type of application.
Schematic diagram for a 4 wire pressure mat In a 4 wire configuration the two wires on the far left are the tamper loop. These are only needed when connecting to an alarm control panel. The two stripped wires on the right are the normally open pressure mat contact.
