Integrated alignment viewfinder allowing a single operator to perform the settings and the configuration manipulations with no additional equipment (buzzer + LEDS reception level testers). Since cells are D.I.S. cells, the alignment procedure can be performed on either side of the detection zone, and the alignment of one transceiver automatically leads to the optimal alignment of the integrated cell.
With D.I.S technology, the IR cells cumulate transmitter and receiver functions, hence alarm contacts are available on all columns. This feature will reduce wiring constraints.
