January 2017 www.actionair.co.uk Health and Safety All wiring should be carried out in accordance with the wiring details provided by the IEE and BS regulations and by a competent person. Care must be taken when installing and inspecting dampers, as they are likely to close without warning due to loss of electrical power or a temperature rise in the ductwork. This is their prime function. Do not insert any items, fingers or limbs between the blades. Larger dampers must be handled in accordance with current regulations and good practice due to weight. Control Mode Installation Procedure
- Remove transit plate and recycle.
- Slide the interface and mode assembly into the shroud. Ensure the slots in the interface casing and the drive coupling located on the rear of the interface are in line.
- Push the assembly fully home until the interface sprung retaining pin engages through the locating hole in the damper shroud (snaplock™). The control mode can be fitted in any of three orientations i.e. vertically down, horizontally and vertically up (For height restrictions). This can easily be carried out by the following:
- Remove and retain screw (8mm A/F) and washer, through the position indicator on the control mode.
- Remove the control mode and location plate.
- Taking care not to disturb the drive hexagon. Replace the location plate and control mode in the new orientation.
- Replace the washer and screw tight (Max 5Nm) Select a suitable position for the Electrical Thermal Release (ETR) to be mounted through the ductwork. Ideally this should be in the top half of the duct and/ or above the level of the interface. Apply the self-adhesive template (located on the rear of the ETR) and drill the necessary holes (Ø3mm & Ø9.5 & Ø11mm). Push the ETR through the duct and ensure both screws are used to hold it in position. Both screws should be tightened fully to ensure that both sections of the ETR are closed together. It is a safety feature, if both sections are not closed the unit will not operate. For ductless installations the ETR should be fitted onto the damper spigot (not casing) above the damper interface shroud and in accordance with the fitting instructions. If the ETR is not fitted in the exact manner described above, the unit will not operate. The damper should be manually reset and released using the winder provided to ensure that correct mechanical operation is achievable. It is possible to mechanically lock open the SmokeShield PTC damper to allow air to pass through it using the winder provided, this may be necessary if electrical power isn’t available yet. The ETR is not operable in this instance, the damper will not release automatically if the temperature rises or a fire occurs. The unit must be wired as detailed. When power is available, the unit must be checked for correct electrical operation. Power on to reset, power off to release. The unit must also be checked by pushing and holding the test switch on the ETR to confirm that the damper releases. When pressure is removed from the switch the damper resets. This may also be done after the initial installation test, to provide periodic operation of the damper to simulate actual fail-safe release under smoke/fire conditions. The ETR cable must not cut to shorten or lengthen, and care must be taken not to damage it. Either will render the unit inoperable and void any warranties. This is due to a built in safety feature. SmokeShield PTC Damper Control Modes SmokeShield PTC - ES Rated Fire Damper (Fire & Smoke Barrier) Control Mode Wiring Procedure If integrating this unit with an Actionpac damper control system (LNS, EMS or EMB) please refer to the relevant catalogue and specific project details. General One metre of halogen free low smoke and fume electric cable is fitted to each control mode for convenience of on-site wiring. This provides the distinct safety advantage of all electrics terminating outside the duct, eliminating potential induct fire hazards from wiring faults. The Electrical Thermal Release is prewired with 0.5m halogen free low smoke and fume cabling to Control Modes 5 and 6. A Manual test switch fitted on the ETR allows periodic operation of damper, simulating actual fail-safe release under smoke/fire conditions. Troubleshooting Product Commissioning & Maintenance Available Below is a quick guide to problems that may be encountered. Please note modifications made to units will invalidate warranties etc Fault Possible problem Recommended action Interface Mode Assembly does not fit into the shroud on the damper Damper drive shaft not in line with shroud Gentle adjustment made by manually setting blades to fully closed Mode not in released position Release clutch on motor using manual key. Check the slot on rear of interface Slots on the non-access side of the shroud may be blocked (due to removal of transit plate prior to backfilling) Ensure adequate clearance Control mode does not operate electrically The ETR is not correctly fitted to duct Screw fix to duct ensuring both parts of the ETR are fully together. Do not over tighten The mode is incorrectly wired Check wiring in accordance with procedures The ETR cables have been damaged or tampered with Replace with new mode Control Mode operates, but limited, or no movement of damper blades is observed The mode is not correctly synchronised with the interface Remove motor from interface. Check motor in fully released state. Set position of interface, and refit motor with label upmost, include motor location pointer and washer The damper is damaged or poorly installed New damper or re-install Interface not fitted correctly to damper Fit interface correctly, ensure retaining pin protrudes through location hole in the shroud Foreign matter is impeding blade movement Check and remove Motor location pointer omitted Fit new pointer Mode not screwed down correctly Check and tighten South Street, Whitstable, Kent, CT5 3DU Tel: +44 (0)1227 276100 Fax: +44 (0)1227 264262 Email: firstname.lastname@example.org Website: www.actionair.co.uk Assessed to ISO 9001:2008 LPCB Cert No. 17 LPS1162 Cert No. 017a LNNN00357 (3.1)
