Cables
It is very important to use the correct cable sections and sizes to make sure that the Smoke and Heat Extraction system
meets the standards and works correctly in case of emergency.
The two most important factors are the ability of the cables to resist heat and to make sure that the voltage drop in the
cables to the actuators does not exceed the max. value (15% for most systems) at full load of the SHE-hatches.
Fire resistant cables according to IEC 60331 must be used for the following functions:
Normal cables can be used for the following functions:
Nominal motor current for each opening system (current per system):
Max. motor cable length:
Opening systems with actuators 24V 2 or 3 wires: section: see table “Max
motor cable length”
Fire switch 6 x 0,5 mm²
Smoke detector 2 x 0,5 mm²
Heat detector 2 x 0,5 mm²
Cable between control units (bus) 3 x 0,5 mm²
Priority switch 4 x 0,5 mm²
Supply for control 230VAC 3 x 1,5 mm²
Comfort ventilation button 3 x 0,5 mm²
Wind- and rain sensor 3 x 0,5 mm²
* Only to be used to determine the
max motor cable length with the
table below.
* * Generally use 1 Slave control per
opening system. This results in
short motor cables.
