This is a 4-storey
building.
The surface area of a
floor is 40 x 70 m.
The distance between
the floors is 5 m.
EL-2 control panel, using
lines A and B.
7 pcs EL-16-AS16m signs @10NU
48 pcs EL-DL2-AS safety lights @4NU.
Total power requirement: 262NU/floor.
Because of the number of luminaires, both A and B lines must be used.
In the floors the cabling is done by taking the cable through the length of the floor and branching there to
different spaces. The distance to the furthest luminaire is approximately 20 + 70 m = 90 m.
The riser cable between the floors conveys twice the number of power units compared to the floor. Because
the riser is rather short, this is not of real significance. Considering this, we can inspect each floor as a
separate cable, noting that the total power consumption does not exceed the maximum.
The cable parameters graph shows that the 262NU power requirement of the floor allows for full 1000 m
cable. Because the distance to the fourth floor is 105 m, we can do the cabling with a single conductor pair
KLMA 2x 0.8 + 0.8.
