Actionair Trans/Shield Modes 1 & 2
Transfer Stainless Steel Sliding Plate Fire and Smoke Dampers 


The Trans/Shield Damper complete with 18 gauge stainless steel Sliding Seal and Static Damper Plates with horizontal perforations which provide, whilst the Seal Plate is in the open position, a free area of not less than that of the specially designed Grilles, for the passage and transfer of ventilation air in either direction. The Damper Sliding Plate is retained to the Damper Static Plate with stainless steel shouldered rivets and fails-safe to the instant closed position, powered by two stainless steel tension springs, with the melting and parting at a temperature of 72 °C of an all brass Fusible Link attached to Sliding Seal Plate, to form a fire resistant shield from either air flow direction. The Fusible Link functions independently and regardless of choice or status of Release and Reset Mechanism.

Slimline Casing
Both Damper Plates together with a choice of two interchangeable and replaceable Release and Reset Mechanisms with both being self contained in a removable Cassette.



Matched Transfer Grilles
A pair of specially designed matching non vision Transfer Grilles with radius edges and countersunk fixing holes are always supplied with each Trans/Shield Damper forfitting to both sides of door or dry wall/partition. The Transfer Grilles are constructed in 18 gauge galvanised mild steel finished in Polyester Powder coat to RAL8025 gloss brown, as standard.

Control Options


A choice of two interchangeable and replaceable Release and Reset Mechanisms is available with either a Manual Release (Mode 1) or a Manual and 24 Volt D.C. Electro Magnet Release (Mode 2) being self contained in a compact Cassette with simple screw attachment direct to the Damper. For easy withdrawal without disturbance other than the removal of the relevant Transfer Grille. Removal of the Release and Reset Mechanism Cassette provides the further fail-safe feature of Damper instant closure which cannot be reversed until the proper replacement is made.

Control Mode 1
A fusible link actuates the instant closure of the damper due to an abnormal rise in temperature.

Control Mode 2
The 24 Volt D.C. Electro Magnet is normally energised to hold open the Trans/Shield Damper, which will instantly close when the electrical supply is interrupted, either as a function of a smoke detection system or due to failure of the electrical supply and in both events, prior to the operation of the Fusible Link on temperature rise or a full fire condition. It is recommended that the continuous electrical supply (83mA Load) to the 24 Volt D.C. Electro Magnet is through a battery circuit and not an automatic change-over system.
 

Indication of Damper Status


The Trans/Shield Damper on closing, automatically disengages a spring loaded Damper Set and Status Pin, which is encapsulated with a distinct red plastic capping, providing visual indication of Damper status.
