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 2.7.2.4.
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.

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 3 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.
