Damper Installation Method
- Mark out the hole on the partition and cut it out, cutting the top and bottom edges first to maintain stability.
- Frame out the hole with stud and track and cover this with 2 layers of board. Finish edges with joint filler.
- For Masonry walls commence from item 4.
- Make sure the area within the aperture is free from any debris and remove any dust.
- Where the coated BATT will be in contact with the surrounding aperture and where two coated BATTs are in contact use Rockwool fire pro glue, ensuring that an even cover is achieved over the entire thickness of the BATT.
- Continue installation of Rockwool ablative coated BATT, until aperture is completely filled.
- Apply a bead of Rockwool acoustic sealant to both sides of the wall, approximately 15mm wide around perimeter of the aperture between dry wall and BATT, ensuring that any gaps between the BATT and surrounding edges are fully filled.
- Allow 12 hours for BATT penetration seal to cure.
- Mark and cut circular hole into BATT, Install the damper and fasten one Installation Flange so that the blade in its closed position is in the centre of the wall.
- Fit the remaining Installation Flange
Actuator Fitting (If required)
- The control mode/actuator should then be fitted using the instructions supplied with it.
- Using the supplied drilling template, drill into the ductwork and fit the Electrical Thermal Release (ETR) into the duct (as good practice, this should be towards the top of the duct).
- A special feature of the actionair SmokeShield modes is that they may be adjusted from pointing straight out along the duct (standard configuration) through 90° to point either up or down if required.
- The mode should be wired into the system using the site wiring detail, plus the details shown on the label. Note: If the mode/actuator fitting instructions are missing, please contact the actionair sales office.
The procedure detailed under periodic maintenance should be followed.
The manually resettable fire damper should be carefully inspected, cleaned and lubricated with light oil, if required, released and reset.
The motorised fire damper control mode should be operated to ensure that it is moving the blades from open to close and vice versa.
If the end switches (in the control mode) are being used, it must be checked at commissioning stage that they are actually indicating that the blades are open or closed. If using an automatic control system this can be achieved by running a test cycle and checking the blades (open and closed) and the status indication at the control system.
