Cable for D+H Smoke and Heat Vent Systems
The smoke vent control panel is designed
for opening smoke vent devices, which
operate by thermal ascending force and by
automatic fire recognition devices (thermal
detector, smoke detector), and they release
either self-acting or manual by smoke
detectors at an early stage of a fire, and
remain in opened position without further
power consumption. In these cases,
functioning preservation of the electrical line
system is required only at an early stage of
fire. Protected wiring is required with
protection against mechanical damages
according to DIN 18232 section 2.5.5
paragraph 4.
Control Cable (Group):
Cable from the smoke vent control panel to
connection of drive (drive lines have a
monitoring wire, in which fire recognition
devices (thermal maximal detector e.g. THE)
can be looped-in):
- Safety line, with functional conservation
... E30, according to DIN 4102* or standard
guidelines for line systems MLAR.
Line lengths and Cross sections:
Number of wires and cross-sections indicated, refer to required lines only. In case of
using a line with earthed conductor (green/ yellow), this one will not be counted in and
must not be wired.

2 conductors per drive line wire -MOT- in parallel!
*** Applies only to drives with 1A motor current.
Use "160" for drives with 0,5A motor current.

Detector Cables (Line):
The detector cables are monitored for short
circuit and for break.
The opening device is automatically
triggered and opens up in case of fault, when
DIP-switch 2 is on ON.
Smoke vent button cable and cable of
automatic detectors:
- weak current sheathed flexible cable YR
6 x 0.8
or
- house wiring cable IY(ST)Y 4 x 2 x 0.6
Cables through areas not monitored:
An increased time of functioning of the cable
can be required, when drive lines are
installed through building parts, which are
not monitored.
- Safety line with functional conservation
... E90, according to DIN 4102* or standard
guidelines for line systems MLAR.
(see supplementary sheet 1 to DIN VDE
0108)
* Notice: No type designation is given
for these cables, because of a large
variety on the market. Please consult
your D+H distributor about these.
