4.2 SENSOR INSTALLATION
4.2.1 SENSOR MOUNTING SURFACE
The surface on which the sensor is mounted
must be sound and reasonably flat. The
sensor can tolerate minor irregularities but
sharp edges or projections greater than 1mm
may cause premature degradation. Where the
surface is rough, cracked or breaking up, it
should be treated using proprietary sealing
and levelling compounds.
4.2.2 SENSOR FIXING
The sensor(s) must be fixed permanently in
position. Tapeswitch aluminium edging
AE-13 should be used around the outer edge
of the sensor. This specially designed edging
comes in two parts, a base and a cover. The
cover provides a 20 degree ramp to prevent
a tripping hazard at the outer sensor edges.
Type AE-13 edging is illustrated in Figure 6
and AE-C corner pieces in Figure 7. At the
junction of several mats, the mats should be
fixed to the floor using double sided tape.

4.2.3 INSTALLATION PROCEDURE
Step 1 - Plan the layout. Mark out on the floor
the position and size of each sensor. Take
care to use the overall dimensions of mat
sensors.
Step 2 - Cut all edging to size. Remove any
burrs and sharp edges with a file.
Note: If AE-C corner pieces are used then:
the cut length = mat dimension - 12mm.

Step 3 - Mark the positions of the sensor
cables and cut slots in the inner face of the
edging base extrusion to allow access for the
sensor cables.
