FireFlex® FLX-PC Controller

The patented FLX-PC device is used to precisely monitor and control the vacuum level in the piping network, display the vacuum pressure, vacuum pump run time and frequency of pump operation, in real time, thus providing useful information in regards to major changes in the piping network.

The FLX-PC Vacuum Pressure Controller controls the vacuum pump and is programmed to maintain vacuum pressure in the piping network between -180 mbar (-2.6 psi) and -150 mbar (-2.2 psi).

The piping network within the FireFlex®’s Vacuum Fire Protection System is supervised by the FLX-PC for vacuum pressure under normal conditions. In case of a fire, it will
detect a sprinkler activation, generate an alarm and trip the system in less than 5 seconds. The FLX-PC also supervises the vacuum pressure for low and high levels and supervisory signals are provided.

What FireFlex® VACTEC® units are made of?

FireFlex systems are made of industry-recognized components. We’re proud to work with these amazing partners.

Renowned Control Panel

The Viking VFR-400 is cULus Listed, FM Approved and meets UL 864-9 requirements. It features onboard menu-driven programming with twelve pre-installed programs to facilitate set up.

The panel is compatible with multiple initiating devices such as: linear heat detection, smoke and heat detectors, waterflow indicators, low & high air pressure switches as well as manual pull stations.

_CAR6686_2
The Viking VFR400 is a microprocessor based multi-hazard releasing control panel for use on dry-pipe and preaction configurations.

Aligned with key NFPA Requirements

We are actively involved in supporting and training the fire protection practitioner at all levels—including industry-related associations such as NFPA, SFPE, AFSA, NFSA and ASPE.

Releasing Circuit Disconnect Switch

Required by NFPA 72 - 2010 Edition, this feature is standard on all our FireFlex® VACTEC® units and prevents accidental discharge during maintenance or inspection. Operation of the key switch physically disconnects the release circuit wiring and causes a trouble signal at the releasing control panel.

CORROSION INHIBITION

Negative pressure-based FireFlex®’s VACTEC® system and its vacuum technology provides inherent corrosion inhibiting capability by removing oxygen and moisture from the piping.

Economical & Efficient long-term Solution

It offers an economical and long term solution on applications where piping corrosion, clogging or ice plugs can affect system performance or where maintenance issues are a concern.

The inhibiting atmosphere is quickly created, only a few minutes after you start the system, normal vacuum pressure is reached thus creating the proper atmosphere to inhibit corrosion. The system pressure is then monitored in real-time by the FLX-PC controller ensuring a proper level at all times.

C Factor

For corrosion mitigation measures, it is important to ensure that water is kept out of the piping network during its standard operation or supervisory mode. C-value of 120 can be used for design purposes when such measures are able to be fully implemented as outlined in FireFlex®’s design manual.

Suitable Applications

Integrated Vacuum Fire Protection Systems can be used to protect all applications requiring the following types of systems: The corrosion mitigation properties of the Vacuum technology make this technology suitable for all applications where piping corrosion or pipe clogging is a concern.

  • Large parking garages where corrosion is often a concern.
  • Freezer protection is also a suitable application, where no ice plugs are formed in the piping network
  • The vacuum pump removes residual water in the riser each time it operates to maintain the proper vacuum level. No condensation problems occur, and no additional special equipment is required.
  • Storage applications where not heating the building can significantly reduce operational costs.
  • Mission critical and sensitive areas where water damage is a concern. Leaks in the piping network will not allow water droplets to escape, vacuum pulls air from outside and water, if any, will stay in the piping network.

Riser Shut-off Valve & Vacuum Pump

For easier maintenance the riser shutoff valve comes as a standard on all units. As for the vacuum, it is created using a water ring seal vacuum pump controlled by the FLX-PC.

Riser Shut-off Valve

It consists of a supervised butterfly valve which allows for a full flow trip test without flooding the system’s piping and a sight glass located on the main drain for visual indication of the water flow.

Vacuum Pump

The vacuum is created using a (1.5 HP, 208V-240V/60Hz 7 Amps) water ring seal vacuum pump controlled by the FLX-PC.

The vacuum pump used in the system allows for very quick startups. The required time to establish maximum supervisory vacuum level in the piping network is less than 4 minutes for a 1000 gallon system thus saving start-up and maintenance time in the field.

Quiet running and minimal vacuum pump maintenance requirements offers significant advantages compared to air compressors.
