DIP switch 1 from S1 and S2 ON = At alarm on one line the other line will be switched
on automatically, that means all groups will open.
DIP switch 2 ON = In case of a line fault (e.g. break in button wiring or missing terminal
resistor), the control panel switches to alarm status, i.e. the smoke
vent opens.
DIP switch 3 ON = A smoke detector alarm cannot be reset by pressing the button in
the smoke/ heat vent button unit once.
If you require a remote reset facility for the smoke detector using the smoke/heat vent
button, DIP switches 3 must be OFF.
DIP switch 4 ON = The vent closes completely after the vent button has been pressed
once.
If DIP switch 4 is OFF, the vents will only close as long as the vent button is pressed.
After that it is no longer possible to close the vents using the smoke/ heat vent buttons
or weather control!
DIP switch 5 ON = The vent opens completely after the vent button has been pressed
once.
If DIPswitch 5 is OFF, the vents will only open as long.
Coding line and group
The following functions can be coded on the control panel using the DIP switches on the
mainboard.
DIP switchblock S1 codes Line 1 and Group 1
DIP switchblock S2 codes Line 2 and Group 2

Maintenance
Onceayearby a specialist company, whois
authorized by the appliance manufacturer.
Renew test badge, keep control book.
Respective current D+H maintenance
instruction is decisive.
D+H authorized expert companies are
specially trained by D+H for carrying out this
maintenance compentently, and therefore
they are automatically provided with relevant
maintenance instructions.
Following tests must be carried out with
maintenance:
- Outside examination/ inspection of system
components
- Measuring of insulation resistances
- Checking of all relevant power supply units
- Functional testing of connected system
components
- Record of competent carrying-out of
maintenance, and designation
according to directions
Every 6 months and after specialist or other
qualified personnel has taken the system
into operation.
Eliminate faults without fail. Keep a log book.
Inspection:
Check all devices and cable connections for
visible damage and dirt. Fire detectors, smo-
ke-vent buttons, smoke vents, etc. must not
be impeded in operation by storage goods
or reconstruction measures.
Function:
Continually activate a different smoke-vent
button (smoke detector) per line during each
new test.
Open the smoke-vent button. First all open
the system, then close it again.
Activate fire detectors with D+H smoke-
detector test unit or cigarette smoke. Re-
sponse time-lag approx. 20 sec. The red
LED must light up, and the smoke vent must
open.
Closing after automatic activation by smo-
ke detector:
Wait until the detector no longer contains any
smoke.
Use the button in the control panel to
switch the line on / off.
Press the concealed button marked in
the smoke vent unit. The smoke vent closes,
and the red LEDs in the button and in
the control panel extinguish.
When dip switch 3 is switched on OFF, the
flap can be closed directly by smoke vent
button as well. For this press masked key
in button.
Smoke vent closes, detectors will be reset.
If used, activate external control.
The smoke vent must open.
Closing after automatic activation by
external control:
Opening the contact in the external system,
e.g. by resetting the fire detection system.
Press the concealed button marked in
the smoke vent unit.
The smoke vent closes, and the red LEDs
in the button and in the control panel
extinguish.
Check alarm display and all drives for
smooth operation up to final opening/closing
position.
Emergency power supply:
Cut out the main fuse in the distribution
system. Repeat the function test. The green
pilot light in the smoke-vent buttons must
not light up.
The green LED Power in the control
panel must not light up.
Ventilation is disabled.

* Table applies to 1A drives. For 0,5A drives, twice the line length applies.
** 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.
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.

Mounting Arrangements
Connection in case of line branch:
- supply wires
Mot. a and Mot. b branch in parallel
-Monitoring is looped through through all
the cables up to group end.
Example 1:
1 Lane
Simple wiring, however unfavourable for
voltage drop:
All drives on one line.
Example 2:
2 lanes
Control panel in the centre, one side wired as
branch, the other one as terminal line.
Remember 4 wires for branch!
Example 3:
2 lanes on one side
Branch and terminal line in same direction.
Numberofdrives varyaccordingto lengthsof
lines.
Remember 4 wires for branch!
Example 4:
3 lanes
Due to extremely long distances 3 lines are
provided:
2 lines with 3 drives each over 75 m line as
branch and 1 line with 2 drives over 200 m
line.
Remember 4 wires for branch!
