The UCM Height Calculator tool
To use the Height Calculator tool, start the UCM application for the UltraWave sensor, select the
Config tab, and select the Height Calc button. Specify the configuration (single stack, double stack,
or triple stack), choose the units of measurement (meters or feet) and then enter the separation
distance between the transmitter and receiver units. The Height Calculator tool provides the
recommended unit mounting height, the detection zone width, the required offset area, the
mounting angle, and the level of security for the microwave pair. Average snow accumulation can
be specified, and the Height Calculator tool will use the entered snow accumulation data as a
factor in making the calculations. When you close the Height Calculator tool, it makes
recommendations for the optimum Threshold settings.

Note
The Universal Configuration Module (UCM) includes a height
calculator tool that determines microwave offsets, mounting
heights, beam width, and clearance requirements, based on unit
separation. Use the Height Calc tool when planning an UltraWave
zone.
