Safety notes
Smoke gases are to be carried off as unhindered
as possible through smoke and heat vent opening
in case of fire. Size, kind and arrangement of the
opening is of decisive significance for an optimal
effect of the smoke and heat vent system.
These requirements are defined in the relevant
regulations of the respective country.
More informations, are also available under
www.rwa-heute.de.
The SHEV opening should be coordinated with the
responsible fire protection authority.
SHEV opening
An overdue maintenance of the system will be
indicated by the control panel after about ca. 14 to
16 months.
The yellow LED in the smoke vent button and the
green LED (D6) in the control panel will start
flashing.
A malfunction of the smoke vent system will be still
indicated by the extinction of the green LED in the
smoke vent button.
After the maintenance time is expired (approx. 14
to 16 months), the ventilation function OPEN can
be interrupted depending on the presetting of the
service timer.
Attention: Reset of the service timer can be
carried out by a specialist company only, who
has been authorized by the appliance
manufacturer.
Servicetimer
Inspection and maintenance has to be carried out
according to D+H maintenance notes. Only original
D+H spare parts may be used. Repair is to be
carried out exclusively by D+H.
Wipe away debris or contamination with a dry, soft
cloth.
Do not use cleaning agents or solvents.
Repair and cleaning

Cables for D+H smoke an heat vent systems
When selecting and installing the cables, the
regional electrical installation regulations
concerning wiring systems and the necessary
safety equipment, or guidelines on integrity
maintenance of electric lines are observed (e.g.
MLAR).
Notice:
No type designation is given for these cables,
because of a large variety on the market.
Please consult your D+H partner.
Wiring plan (Paragon)
Group cable (control panel - drive)
At least three wire design:
- 2 wires for the supply of the drive
- 1 wire for line monitoring, on which also the
SHEV high speed (HS) signal is transmitted to the
drive. If group DIP switch 7 is ON, the group will in
case of a fault automatically triggered and opens.
Line cable (control panel - detector)
The cables are monitored for short circuit and for
interruption. If line DIP switch 3 is ON, the group
will in case of a fault automatically triggered and
opens.

(When DIP switches S2.8 / S4.8 / S5.8 = ON)
The smoke vents will be triggered with an OPEN-
impulse every 2 minutes for a duration of 30
minutes according to VdS 2581. For this, the
drives must be blockage safe. All D+H drives meet
this precondition. Otherwise the DIP switches has
to be switched on OFF.
Mounting of the drives:
Please take mounting informations from the
relevant instruction for use of the respective drive,
because of varied possibilities for choosing drives.
Drives
Connection of fire detector
Max. 14 fire detectors connectable.
Only D+H approved detectors must be used.
* Terminal resistors for line monitoring
It is pinched in control panel for transport.
Take it off there and connect according to plan.
Terminal resistor must remain at terminal RM 1,2,
when no fire detector or external control exists!

Operation -AdComNet
In case of AdComNet operation (S6.4 = ON) the
ventilation control and alarm release can be
carried out by the local connected line and group
inputs, as well as via corresponding links in the
AdComNet Configurator.The alarm and fault
indicators distinguish between a local message
and a message inside a bus link:
Malfunction LED on the line:
1 Line deactivated: LED flashes
2 local fault: LED lights continuous
3 BUS fault: LED flashes
4 Everything OK: LED OFF
Malfunction LED on the group:
1 local fault: LED lights continuous
2 BUS fault: LED flashes
3 Everything OK: LED OFF
Alarm LED on the line:
1 local alarm: LED lights continuous
2 BUS alarm: LED flashes
3 No alarm: LED OFF
Only if wind detector or rain detector available.
Upon triggering of the corresponding sensor, the
group of the control panel is closed.
If alarm is released by a smoke and heat vent
system, the system will open also in case of wind
and rain.
Do not ventilate via smoke vent button,
because otherwise there would be a danger of
damage by wind or water.
The weather automatic can be switched-off via an
optional automatic switch, if gap ventilation is
required in case of bad weather.
Gap ventilation not possible badis in case of
weather, no automatic switch availableif .
If the weather automatic is switched on , the
system will automatically
close in case of wind or rain.
The system will not
automatically open again,
if wind or rain has stopped.
