Smoke extraction damper - SEDM-D
TPM 155/22
■
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.
■
In the security position (position open), the damper is
ready to extract smoke and heat from the fire, even if all
electric connections to the damper would be
disconnected. The damper has zero energy consumption
if the activation voltage (magnet) is switch off
(recommendation).
Stand-by mode
Security position
■
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.
■
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.

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.
