Connection of fire alarm system
< optional >
* 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!

Drives

Group output:
While an alert, a possible group disturbance will
not notified. Only after reset the alarm, a fault
message will be indicated.
High-speed function (HS):
All D+H drives with SHEV high-speed function are
supported. In daily ventilation operation, a consi-
derable noise reduction is achieved through the
reduced drive speed. In case of SHEV the drives
run with a very high speed to reach the OPEN
position defined within 60 seconds at the most.
SHEV retriggering:
(When DIP switch S1.10 = 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.
