1.2 Installation of the FGS into a SOFT CROSSING (Fig. 3, Tab. 2)

1. 

Prepare a rectangular opening with dimensions 

L

1

 = 

L

 + 260 

mm and 

H

1

 = 

H

 + 135 mm (according to Fig. 1), the opening 

surfaces must be even and cleaned. 

2.  Put together the frame from two parts (1a a 1b) according to 

the wall width, and screw it into place with screws DIN 7982 

C-H 4.2 × 13 included in the pack.

3. 

Prepare the mineral wool installation segments (with density 

 

150 kg/m

3

, thickness 50 mm). First apply the suitable 

fireproof layer/glue (e.g. Isover BSF) onto the FGS installation 

frame at the place of its future placement, assemble and glue 

the filling of the future installation with the same glue. 

4.  Fix the frame to the rectangular opening with screws 

(recommended screws 5 × 100, fabory 29385.050.100; 

screws not included in pack; Fig. 3). Part 1a of frame has to 

be abreast with the wall. Lead the cable for the connect - see 

Fig. 10 and 11. After the glue has dried, the installation frame 

along with the filling are ready for installation.

5. 

Apply the same glue onto the internal surface of the wall 

opening. Also apply the same glue on the external surface 

of the filling glued on the damper surface. Immediately after 

application, place the installation frame into the wall opening 

in such way that will not deform the installation frame. 

6.   After inserting the installation frame into the opening and 

after fixing it, apply the same fire-resistive mastic, at least 

 

2 mm thick layer and 100 mm wide, on the opening filling 

and wall edges evenly from both sides. 

7.  Before the glue dries, remove the unwanted remnants 

 

of the mastic.

8. 

If needed, uncover and clean the installation frame after 

installation.

9. 

Connect the connector with the plug.

10. Insert the closed FGS into the installation frame, join the 

connectors and fix both the upper and lower side of the FGS 

with screws DIN 7504M-SR 4.2 × 25 (Pos. 7; screws are in 

the pack - the amount depends on nominal dimensions of 

the FGS)

11. 

If needed, uncover and clean the FGS after installation.

12. 

Check the functionality of the FGS.

2 Operation and maintenance

2.1 FGS operation

After installation, the functionality of the FGS must be checked 

and set into the open operating position. 

2.1.1 Manual FGS

On the bottom of the front right side, one hole is placed (Fig. 

12). Insert a screwdriver through this hole or a thin object with 

a diameter of 6 mm max, lever up the upper blade and push 

the latch (spring) - this releases the mechanism. Twist the 

blades into the horizontal position (in the direction indicated 

by the arrow - Fig. 13), force against the spring and fix the first 

blade from the top side with the thermal fusible link (Fig. 14).

2.1.2 Motorised FGS 

By connecting a power source according to the relevant 

scheme displayed in Fig. 5-8, activate the actuator and the 

blades will open. For an actuator with the BKN230-24 unit - 

by connecting a power source to the unit BKN230-24, activate 

the actuator and the blades will open.

2.2 Maintenance

Systemair FGSs are maintenance free. Only periodic dry cleaning 

is necessary - no different than entire ventilation systems.

3 Functionality check

3.1 Manual FGS

In the open position, all blades must be fully open and detented, 

and the appropriate signaling circuit must be switched on.

• 

To close the FGS: lever up the upper blade with your fingers 

and release the thermal fusible link by pushing with a 

screwdriver in the direction indicated by the arrow (Fig. 15). 

Remove the screwdriver and release your fingers from the 

blade. The blades must come up to the fully closed position 

and remain there detented. 

• 

After reaching the end position of the blades, the appropriate 

signaling circuit must switch on.

After checking, set the FGS into the open position (that is the 

operating position; see Chap. 2.1.1). 

3.2 Motorised FGS

After connecting the supply connectors (see Fig. 10 and Chapter 

2.1.2), the FGS opens.

•  The blades must come to the fully open position and must 

remain there detented.

• 

After reaching the end position of the blade, the appropriate 

signaling circuit must be switched on.

After disconnecting the supply connector (see Fig. 10) - e.g. by 

means of pulling the FGS out of the frame - the FGS closes.

 

DO NOT COME IN CONTACT WITH THE BLADES DURING THEIR 

MOVEMENT TO AVOID RISK OF INJURY!

•  The blades must come up to the fully closed position and 

remain there detented.

• 

After reaching the end position of the blades, the appropriate 

signaling circuit must be switched on. 

After checking, set the FGS into the open position (that is the 

operating position; see Chap. 2.1.2).
