SmokeShield Product Specification

SmokeShield PTC™ Proportional Torque Control, CE Marked ’ES’ Rated Fire/Smoke Dampers. Opposed bladed with 75mm x 0.5mm thick stainless steel aerodynamic interlocking blades incorporating synthetic seal, with steel blade end bearings and peripheral gasketting. Housed in a galvanised steel fully welded 1.2mm spigotted casing suitable for square, rectangular, circular or flat oval connections. 

The totally enclosed precise movement opposed blade drive shall be positioned out of airstream for protection against damage, be hard wearing and free running. 

The Control Mode/Damper connection shall be by means of the snaplock™ drive interface mechanism, which is totally independent of the ductwork 

SmokeShield PTC™ ’ES’ Rated Fire Dampers with their appropriate control modes shall have spring Fail-Safe Closed operation only, with selected Control Mode (M5 24V, M6 230V, M5 - 3P 24V) as supplied by Actionair. 

Also available with Schischek ATEX rated actuators. 


Application Parameters

The SmokeShield PTC™ range of Fire/Smoke dampers are CE Marked ‘ES’ Rated dampers used to prevent spread of fire and smoke maintaining compartmentation.

SmokeShield dampers up to maximum width and height dimensions can be used where the operating total system pressure is up to 1500 Pascals and duct velocities to 15m/second. The SmokeShield PTC™ Damper blades are open and fail-safe to the closed position. Dampers may be installed both vertically and horizontally. Airflow can be from either direction. 

Actionair SmokeShield PTC™ Dampers are designed for applications in normal dry filtered air systems. If exposed to fresh air intakes and/or inclement conditions, the dampers should be subject to a planned inspection programme. 

For specialist and/or aggressive applications, please contact us. 


Testing

CE Marking

SmokeShield is CE Marked Product. To achieve the CE mark fire dampers must fully comply with the following product standard:

  • EN 15650:2010 Ventilation for Buildings - Fire Dampers and compliance is verified through assessment by a ”Notified Body”. 

The full and intensive assessment process includes; 

  • Fire testing to the latest European standards - EN 1366-2 
  • Classified to EN 13501-3 
  • Corrosion testing to EN 60068-2-52 
  • Thermal fuse testing to ISO 10294-4 
  • Factory production control which includes a continuous program of cyclic and leakage testing of production dampers to ensure full compliance of every product 

Fire Damper Fire Resistance Test 

The EN 1366-2 (Test standard) gives requirements for testing dampers to the standard time/ temperature curve with a requirement to close within two minutes of the start of the test with a constant air flow of 1.5m/second. After closure a 300Pa pressure differential is applied to the damper and the damper leakage (corrected to 20°C) is recorded throughout the rest of the test. The largest size of damper to be offered for sale must be fire tested. Pass and fail criteria is included in the standard. 

  • E (Integrity) - the damper must leak no more than 360m3/hr/m2 at any point during the test. 
  • ES (Integrity and Leakage) - the damper must leak no more than 200m3/hr/m2 at any point during the fire test. This also applies to the largest and smallest size of damper to be offered for sale at ambient temperature for the ES criteria to be applicable. 

Spigot Connections/Casing

Casing Features

With double skin spigotted galvanised steel (to BS EN 10346:2009) 1.2mm thick casing the SmokeShield PTC™ ‘ES’ classified Fire/Smoke Dampers comply to Class A and B of Eurovent Document 2/2 and Test Procedures for Classes A, B and C of HVCA Ductwork Specification DW144. 

Spigot Connections

Damper casings are manufactured with welded spigotted connections suitable for Square / Rectangular SS501, Circular SS601 and Flat Oval SS701 duct connections. 


Blade Features

SmokeShield PTC™damper blades are aerodynamic double skin, Type 1.4016 (430) Ferritic stainless steel, which are 75mm x 0.5mm thick and interlock to form a positive smoke and fire resisting shield. Incorporated within the blade profile is a synthetic seal to ensure low closed blade smoke leakage.  Stainless steel blade end bearing and peripheral gasketting maintain the low closed blade smoke leakage whilst allowing for expansion under full fire conditions. 


Control Modes

Control Mode Options

A choice of three Motorised Control Modes are available: 

  • Control Mode 5 (M5 PTC) 24V (Open / Fail-Safe Close) 
  • Control Mode 6 (M6 PTC) 230V (Open / Fail-Safe Close) 
  • Control Mode 5 - 3P (M5 - 3P PTC) 24V (Open / Control / Fail-Safe Close) 

The Control Modes are located outside of the ductwork for easy installation and access. 

Control Modes 5, 6 and 5 - 3P Electrical Optimised motor/spring return control modes with remote reset-release facilities, and with volt free contacts for provision of external indication, monitoring and control by means of an Actionpac damper control system, or by a suitable alternative proprietary control format. 

Further information on each control mode is available in the catalogues and datasheets at the bottom of this page.

Three Position Configuration

All of our Control Modes (5, 6 and 5 - 3P) can be fitted in 3 positions through 180° allowing maximum on-site installation flexibility. 

  • Vertically down 
  • Horizontally
  • Vertically up

This can be simply and easily carried out on site,by repositioning the Location Plate and Control Mode on to the snaplock™ Drive Interface. This flexibility ensures that the damper and control mode require the minimal amount of room

Note: All SmokeShield Control Modes must be in the released position prior to connection. 

 

snaplock™ Damper/ Control Mode Interface

The Control Mode operates the SmokeShield through a unique drive system. The snaplock™ Damper/ Control Mode Interface. 

Automatic ’ES’ classified Fire/Smoke Damper and Control Mode assembly with a unique and dedicated Proportional Torque Control for optimised Damper/Control Mode torque performance. The unique snaplock™ drive interface ensures user friendly, easy and secure connection of the Control Mode to the damper. 

The drive interface which is totally independent of the ductwork, eliminates the need for costly dedicated duct sections, and provides ease of connection to square, rectangular, circular and flat oval ductwork. 

This drive interface guarantees that only the correct and certified Actionair products can be used. 

Electrical Thermal Release (ETR) 

Dampers are fail-safe by means of a unique and patented electrical thermal release which operates at approx 72 °C or if power supply is interrupted, tested to ISO10294-4 and complying with BS 9999 : 2008 (Ref 33.4.5.3). 

The ETR incorporates triple safety features, including an ingenious device that ensures the fail-safe status of the damper if the ETR is not fitted on to the ductwork. 

A manual test switch allows periodic operation of the damper for testing purposes simulating actual fail-safe release under smoke/fire conditions. 

For safety reasons the ETR is designed to operate once only when the activation temperature is reached.

Maintenance

The SmokeShield PTC™ Dampers are designed for applications in normal dry filtered air systems. 

Adequate access must be provided to fire dampers to enable inspection, maintenance and cleaning. This would normally be in the form of access panels/doors. At least one access point is required for access, but access both sides may be required for cleaning (refer to the relevant ductwork cleaning standards) Dampers require cleaning and light oil lubrication. 

Regular testing/inspection by suitably qualified personnel shall be undertaken. The requirements in BS 9999 should be checked, as these products may form some part of a controlled system that responds to alarms. Some automatic systems may allow more frequent testing (48 hours or less), but physical inspection is still required at the prescribed intervals. Some systems, where cleanliness is an issue due to site conditions, may require more frequent inspection, testing and cleaning. All such inspections should be recorded.
