Masonry Wall & Flange

 

Damper Installation Method

  1. Drill clearance holes in the damper flange at 150mm centres.
  2. Install the damper and fix through flange using steel anchors min ø6.5mm.
  3. Back fill between damper casing and wall, with mineral/stone wool and secure in place with angle retaining flanges, fixed in corners, or with Z shaped retaining flanges, to give the option of face fixing onto wall. Note: either angle or Z retaining flanges to be supplied by others.

Actuator Fitting (If required)

  1. The control mode/actuator should then be fitted using the instructions supplied with it.
  2. 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).
  3. 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.
  4. 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.

Commissioning

The procedure detailed under periodic maintenance should be followed.

Periodic Maintenance

See periodic maintenance.

Procedure

1) The manually resettable fire damper should be carefully inspected, cleaned and lubricated with light oil, if required, released and reset.

2) The motorised fire damper control mode should be operated to ensure that it is moving the blades from open to close and vice versa.

3) 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.
