•
The limit switch for the "CLOSED position" (S1 contact with S2) of the smoke control damper is actuated at angle position < 3°.
•
The limit switch for the "OPEN position" (S4 contact with S6) of the smoke control damper is actuated at angle position ≥ 87°.
•
The intermediate position is signalled in angle position > 3° and < 87° (S1 contact with S3 and S4 contact with S5).

Series EK92
The
electric drive
is located to the side of the smoke control
damper, inside the calcium silicate
casing
.
The motor drive can be accessed by unscrewing the casing cover.
Electrical cables should be guided through the walls of the casing
for the motor drive on site.
Holes should be arranged for these as shown and matched to the
diameter of the cables.
Depending on the height H of the smoke control damper, motor
drives with difference performance data can be fitted:
