III. DAMPER CONTROL
Stand-by mode
In the stand-by mode (the damper is closed and waiting
■
for the activation signal) the damper does not need any
supply voltage and has zero energy consumption.
Activation
In accordance with the harmonized Standard, the damper
■
has no self-activation function [non-autocomandé]. The
damper is remotely activated [télecomande] by voltage
pulse [émission du courant].
Switch ON the voltage of 24 V DC or 48 V DC, respectively,
■
on MAG- and MAG+ for at least 1 second to activate the
damper.
Rearming
Rearming means getting the damper back to the stand-by
■
mode. The activation (magnet) voltage shall be safely
switched off before starting the rearming process.
Rearming should be carried out with the smoke extraction
fan off for safety of persons and equipment.

Security position
In the security position (position open), the damper is
■
ready to extract smoke and heat from the fire, even if all
electric
disconnected. The damper has zero energy consumption
if the activation voltage (magnet) is switch off
(recommendation).
To test the damper during the commissioning (with the
■
protection grille removed or open), the damper may be
activated also by-hand, by pushing the handle of the
restraint mechanism in the direction to the center of the
damper, as indicated on the damper by an arrow.
After the activation, the damper opens within 5 seconds
■
(using energy stored in springs integrated into hinges) and
secures automatically in the open (security) position.
