Introduction
Aligning lines and zones with each other makes for a neat setup but importantly it is recommended for high accuracy counting and is even required in some applications.
Aligning an IN and OUT line for example ensures that everyone going In and out through a doorway will be treated the same. It ensures that you can't enter a room and be counting correctly but bypass a line on the way out.
Similarly, aligning the various zone type registers ensures that - for example - a 'Staff Call' and a 'Staff Attend' register are working on the same footing, and will prevent one signaling without a corresponding signal from the other.
For Occupancy counting applications where occupancy is calculated by subtracting the total OUT counts from the total IN counts from all the doors to a building, aligning the In and Out lines on every device is required to ensure that no incorrect counts creep into the calculation. Once anyone is missed the occupancy calculation will be incorrect by that amount of missed counts.
Steps To Align Lines
In this example, we will go through the steps to align two basic counting lines used for IN and OUT.
Firstly, if you have lots of lines and zones, to make it easier to perform the alignment, it is recommended that you hide all but the two to be used, i.e. the one to be aligned and the one to align to. Just click the 'eye' symbol on the Registers dialog:
Now go into Edit Mode.
Obviously, you should make sure that your main counting line is in the right place before you align the other one to it. Here we will be aligning the red (out) line with the green (in) line.
Just click the 'Align' button when ready:
Now click the line that you want to move. Notice how the red line becomes highlighted when the mouse pointer is over it:
Now click the line to move to, the green line in this case. Again it becomes highlighted when the mouse pointer is directly over it:
The line will now move:
It is important to note that the red line is now in exactly the same place as the green one and as such obscures it. At this point, if you want to, you can choose to hide the red line and you'll see the green line appear.
Importantly, note that the direction of the red line has also been copied, which means the IN and OUT line are now both counting IN. To correct this click the 'Flip' line button:
Again, click the line to flip. It will be highlighted as before when the mouse pointer is directly over it:
The lines will then be correct:
In this case there are two other lines used for separate adult and child counting so these too should be aligned.
