The FireFlex® DUAL Cabinet
Factory assembly of the FireFlex® DUAL cabinets ensures that all components have been carefully integrated. All systems are fully programmed and tested at the factory which facilitates the onsite installation and commissioning process.
The FireFlex® DUAL cabinets are of the freestanding type and are made of robust 14 gauge steel with a corrosion resistant fire red paint finish, polyester powder-coated and oven-baked on a phosphate base. Cabinets are also provided with two locked frontal doors that are removable, reducing space requirements for ease of installation and maintenance. Furthermore, all doors are provided with a neoprene gasket to reduce vibrations.
Technical details:
- FM Approved for engineered systems
- cULus Listed for engineered systems
- Compact layout saves floor space
- Fully tested and programmed at the factory
- Unique serial number on every unit
- User-friendly owner's manual with every unit
- Simplified operation and maintenance
- Factory built under ISO-9001 conditions
Construction Options For a Better Flexibility
Remote-controlled Option
The remote-controlled option provides a junction box where all supervisory and control devices, are prewired to a set of terminals for field wiring to a releasing control panel to be provided by others. The system’s electric actuator must be compatible and listed with the releasing control panel.
Seismic Construction Option
- The FireFlex® DUAL seismic construction option is available with or without panel up to 601 lbs cylinder on the 36” and 46” cabinet.
- The seismic construction option is tested and qualified in accordance with:
- International Building Code, 2006-2009 Edition
- California Building Code, 2013 Edition
- ICC-ES AC-156, 2010 Edition
Two styles of air supplies are available for the FIREFLEX® DUAL units depending on needs or configurations. These air supplies are factory assembled and pressure tested.
Air supply style “B”
Used to supervise the sprinkler piping network of preaction systems when the external air supply (by tank-mounted air compressor, plant air or dry nitrogen cylinders) is provided by others.
Note: The air supply must be restricted to ensure that it cannot replace
air as fast as it escapes when a releasing device or sprinkler operates.
The FireFlex® DUAL system uses FFT-1230™ Fire Protection Fluid combined with a Viking Preaction System. Factory assembly of the FireFlex® DUAL cabinets ensures that all components have been properly integrated. All systems are fully programmed and tested at the factory which facilitates the onsite installation and commissioning process.
Combined Sequence of Operation
The combined preaction-clean agent suppression system is configured to prevent unwanted water discharge in the hazard. The clean agent system is typically activated by using a cross-zoned smoke detection system. When the detection conditions are fulfilled, the pre-discharge delay timer is activated. Once the pre-discharge delay expires, the uses FFT-1230™ Fire Protection Fluid is released with the single interlocked preaction system, the piping will fill with water and will discharge in the hazard only if the sprinkler heads have opened. With the double interlocked configuration, it is required that both the detection conditions and the loss of system air pressure occur—further to the opening of a sprinkler— for the water to be released into the system piping. Water will then flow through the open sprinklers.
Riser Shut-off Valve Option
The riser shut-off valve option consists of a supervised butterfly valve which allows for a full flow trip test without flooding the system piping and a sight glass located on the main drain for a visual indication of the water flow.
