2.1. Visual inspection
Check fire damper for damage and contamination
Perform necessary cleaning.
2.2 Thermoelectric triggering – Closing the fire damper
Press switch (pos. 1) on the thermoelectric release
device (pos. 2), thus removing the electric power
from the spring return actuator (pos. 3) (alterna-
tively: interrupt on-site power supply)
Fire damper must close automatically, locking is
performed by blocking the spring return actuator.
2.3 Replacement of the thermoelectric release device (if
necessary)
Exchange takes place by unscrewing the two
screws of the thermoelectric release device (pos.
2).
Remove the thermoelectric release device from
the drive unit. Remove the internal duct tempera-
ture fuse (pos. 4) from the thermoelectric release
device and replace it with a new internal duct
temperature fuse (ZBAT72). Screw the thermo-
electric release device back onto the drive unit.
Carry out a functional check.
