The Fire/Shield range of quality engineered dampers are suitable for air conditioning and ventilation systems requiring up to 4 hour fire protection. These stainless steel bladed Actionair

Fire/Shield Dampers fail-safe closed and are supplied with the new innovative, even easier Single-Handed Reset Self Latching Removable Release Mechanism Cassette, which permits single handed reset.

Application
Fire/Shield Dampers are designed for application in normal dry filtered air systems. If exposed to fresh air intakes and/or inclement conditions the damper should be subject to a planned inspection programme. Any specialists and/or aggressive applications (e.g. swimming pools) may invalidate our warranty, please refer to Actionair Sales Office.

Hot/Shield

 

 

 

 


Actionair has always been at the forefront in the innovative development, design and manufacture of life safety dampers and associated controls. Now with the unique Smoke/Shield PTC™ range of Automatic Smoke and Fire Dampers Actionair continues this tradition.

Application
The Smoke/Shield PTC™ range of Quality Engineered Dampers are suitable for air conditioning and ventilation systems requiring up to 4 hour smoke and fire protection. These aerodynamic stainless steel interlocking opposed blade dampers are fail-safe spring close with manual or electrical reset control modes. The Vent/Shield PTC™ Damper range are reverse acting for smoke release or exhaust. (Motorised Control Mode M5 and M6 versions only)

Catalogues

Construction Smoke/Shield PTC™


HKFSD
No-objection Letter

Smoke/Shield PTC™ High Operating Temperature Smoke Control and Extract Dampers comprising of 75mm stainless steel aerodynamic blades incorporating synthetic seal, with stainless steel blade end bearings and peripheral gasketing. Housed in a galvanised fully welded, spigotted casing suitable for square, rectangular, circular or flat oval connections. The totally enclosed precise movement opposed blade drive shall be positioned out of the 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. Smoke/Shield PTC™ dampers and the in appropriate insulated control modes shall be arranged for motor close and spring open operation.

Control Options

A choice of three Control Modes are located outside of the ductwork for easy access and installation. The motorised Control Modes 5 and 6 can be fitted in 3 positions through 180° allowing maximum on-site installation flexibility. All Smoke/Shield Control Modes must be in the released position prior to connection.

Control Mode 1
Manual reset – with volt free contact for provision of external indication of damper status. Not available on Vent/Shield. Note: Vent/Shield PTC™ Dampers and associated control modes are reverse action with spring opening (only available on Modes 5 and 6).
Mechanical Fusible Link Control Mode 1 (Smoke/Shield only). Fail-safe by means of a unique and patented mechanical fusible link which operates at approx. 69 °C, complying with BS5588 Part 9: 1999. The link assembly incorporates a safety feature that ensures the fail safe status of the damper if the link is not fitted on to the ductwork. A manual test may be performed by simple unscrewing the wing nut situated on the fusible link.

Control Modes 5 and 6
Optimised motor/spring return control modes with remote resetrelease facilities, 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.
Electrical Thermal Release (ETR) Control Modes 5 and 6. Fail-safe by means of a unique and patented electrical thermal release which operates at 69 °C or if power supply is interrupted, complying with BS 5588 Part 9: 1999. 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 69 °C temperature is reached.

Actionair Hot/Shield - High operating temperature smoke management and fire dampers

Hot/Shield

 

 

 

 


Actionair have developed the Hot/Shield PTC™ High Temperature Smoke Management and Fire Dampers along with the Hot/Shield Vent PTC™ Smoke Control and Extract Dampers to enable the concepts of fire engineering to be employed in ducted smoke ventilation systems.
These dampers designed, tested and approved to deliver high temperature operation at up to 300 °C for one hour, provide the designer with the capability of extracting hot smoke and combustion gases through a common smoke extraction duct linked to adjacent fire zones and floors.

Application
As smoke can spread rapidly and efficiently through a building ductwork system, damper operation needs to be initiated by a smoke detection system, as thermal sensing can often be too late. Hot/Shield PTC™ and Hot/Shield Vent PTC™ dampers are designed to be interfaced with a smoke detection/fire alarm system.

Multiple Assemblies for Actionair Smoke/Fire and Fire Damper

Advanced Thermal Enclosure

Actionair have developed a new technically advanced thermal enclosure in conjunction with the manufacturers of the base product to achieve and exceed a total immersion of damper and actuator assembly at elevated temperatures test specifications.
This new enclosure is made from a phenolic composite resin with excellent endothermic properties. A chemical reaction occurs within the insulating material when it is heated. This reaction has the effect of lowering the temperature inside the enclosure, thus prolonging the duration of the actuator’s operation at elevated temperatures.
