1 = ON Drives CLOSE up to final position by single pressing on vent button.
1 = OFF Drives are closing only so long as the vent button or the button "close SHEV" in the smoke
vent button is pressed.
2 = ON Drives OPEN up to final position by single pressing on vent button.
2 = OFF Drives are opening only so long as the vent button is pressed.
3 = ON In case of a line fault (e.g. at an interrupted detector line or short circuit) the control panel
will be switched on alarm, that means the smoke vent opens.
4 = ON In case of a group fault (e.g. in case of an interrupted monitoring line) the control panel will
be switched on alarm, that means the smoke vent opens.
DIP switch must be on ON in conjunction with a ground in thermal maximal detector (e.g.
THE4).
5 = ON OPEN-running time limitation in ventilation operation (Only if DIP switch 2 = ON)
If the vent button is actuated in direction OPEN, the drives open for 30 s (factory-set).
This running time can be edited by PDA servicetool.
6 = ON Ventilation time limitation (Only if DIP switch 1 = ON)
The drives will automatically close again after the time set (factory-set 10 min).
This time can be edited by the PDA servicetool.
7 = ON Power failure "CLOSE" (Only if DIP switch 1 = ON)
In case of power failure the drives will close.
8 = ON Integrated ventilation buttons are activitated.
8 = OFF Integrated ventilation buttons are deactivitated.
The following functions are (de-) activatable with the PDA-Service Tool:
- OPEN running time retriggering (factory-set: deactivated)
- Group CLOSE in case of alarm (factory-set: deactivated)
- Two smoke detectors dependency (factory-set: deactivated)
- Smoke detector alarm remote reset (factory-set: activated)
- Lamp test
- Alarm re-clocking (factory-set: activated)
Hint: In case of alarm the smoke vent is triggered with an OPEN pulse every 2 minutes for a
duration of 30 minutes according to VdS 2581. For this, the drive must be protected against
blockage according to VdS 2580 par. 4.7. . All D+H drives meet this precondition.
- The signalling relay features the following signals:
pre-alarm, terminated alarm, delayed alarm, general fault, battery fault, line fault,
group fault, power failure, earth fault, passing on of "central CLOSE", "Reset Alarm" as
pulse, group closed longer = x sec. (factory-settings: signalling relais 1="alarm"
signalling relais 2 = "general fault")
