16 Cabling Length
16.1 Illumination Points
The voltage level of the control panel’s line out is approximately 39 V (high bit) or 34 V (low bit).
The FIREscape device’s minimum line voltage is 24 V, which means that 15 V can be dropped through the
cable.
The current load for each line is 2.5 A.
For exit route down lighters, the load on the line depends on the set normal light level Luminaires take power
from their own batteries whenever they are activated.
The power consumption of the luminaires is presented in the technical specifications section (see
“Technical
Specifications” on page 46). For cabling, the luminaires’ power consumption is divided into units of 50 mW
each.
The power requirement unit is refer
red to in this manual as an “NU”.
The cabling examples use a 1.5mm²
The number of necessary conductor pairs can be derived from the power consumption of the luminaire points
and the cable length.
16.2 Using the Cabling Recommendations Graphs

Calculate the power consumption units.

Estimate/measure the distance to the last luminaire point.

Check the intersecting item in the graph.

If the intersection item is in between the curves, the number of conductor pairs must be selected
according to the higher curve.
