TOTALPAC 3: How Do You Choose the Right Configuration?
The best TOTALPAC 3 configuration depends on four main factors: the hazard type, the environment, the release logic you need, and the system pressure requirements. TOTALPAC 3 is a modular integrated platform available in multiple configurations, including preaction, deluge, wet pipe, dry pipe, and HP dry pipe.
According to the FireFlex Knowledge Vault, TOTALPAC 3 units are factory assembled, pre-wired, and factory tested under ISO-9001 conditions. The FireFlex website also lists multiple available configurations and notes that the line is cULus and FM approved across several product types.
Start With the Hazard
If the hazard needs water to discharge immediately through open nozzles or open sprinklers once the release condition occurs, a deluge system is usually the right starting point.
If the system should keep water out of the sprinkler piping until detection or sprinkler operation occurs, a preaction system is more appropriate.
If the area can safely use water-filled piping all the time, a wet pipe system may be the simplest option.
If the piping needs to stay dry because of freezing risk inside the protected network, a dry pipe or HP dry pipe arrangement may be the better fit.
Understand the Main Configuration Types
Preaction
The FireFlex website lists multiple preaction options, including:
- Non-interlocked
- Single interlock
- Double interlock
Non-interlock systems can respond to either detection or sprinkler operation, depending on design. Single interlock requires detection before water enters the piping. Double interlock requires both detection and pressure loss from sprinkler operation before water enters the piping.
Deluge
TOTALPAC 3 deluge systems are built around Viking trim and deluge valve arrangements. These are typically used with open sprinklers or spray nozzles and release all required water into the system piping when the release condition is met.
Wet Pipe
Wet pipe is generally the simplest option where freezing is not a concern and immediate water availability in the piping is acceptable.
Dry Pipe and HP Dry Pipe
The Knowledge Vault indicates that standard dry pipe configurations are rated up to 175 psi, while HP dry pipe versions can reach 250 psi and are available in more sizes.
Important Environmental Limitation
One of the most important selection points is environmental suitability. The Knowledge Vault explicitly states that TOTALPAC 3 units are not designed to be installed outdoors or in freezing conditions. If the unit itself will be exposed to those environments, TOTALPAC X is usually the more appropriate product line.
Technical Range and Hydraulic Considerations
FireFlex documentation provides hydraulic usage ranges by system size. For several TOTALPAC 3 configurations, the documented usage ranges include:
- 1.5-inch: 0–210 gpm
- 2-inch: 0–360 gpm
- 3-inch: 100–700 gpm
- 4-inch: 200–1400 gpm
- 6-inch: 400–3500 gpm
- 8-inch: 750–5250 gpm
These figures are for estimation and evaluation only, and final design remains the responsibility of the designer.
Accessories and Options
The FireFlex website and configuration forms identify common options such as:
- Shut-off valve and sight glass
- Fire department connection
- Semi-flanged inlet and outlet
- Relay modules
- Class A circuits
- NYFD kit options on certain configurations
These options can affect testing, maintenance access, and project compliance.
Simple Selection Logic
Choose TOTALPAC 3 when:
- The unit will be indoors in a non-freezing environment
- You want a factory-integrated package
- You need preaction, deluge, wet pipe, or dry pipe flexibility
- You want multiple cabinet and trim options
Choose the specific configuration based on the hazard and release logic rather than starting with the cabinet.
Next Steps
Once you know the hazard and release strategy, confirm environmental suitability and review the configuration form before ordering. That will help avoid choosing a system family that does not match the jobsite conditions.
