FireFlex Shut-Off Valve and Fire Department Connection Options
The FireFlex shut-off valve option adds a supervised shut-off valve, typically with a sight glass arrangement, to support full-flow trip testing on applicable preaction and deluge systems without flooding the sprinkler piping network, making it especially useful in water-sensitive spaces. The fire department connection option provides a factory-prepared tie-in point for FDC piping so supplementary water supply can be connected when required by code, the AHJ, or project design. FireFlex documentation notes that FDC hardware itself is not included and must be supplied by the installing contractor.
Shut-off valve option
Meaning: This option adds a supervised shut-off valve, typically with a sight glass arrangement for trip testing on applicable system types.
Why it matters: It allows full-flow trip testing without flooding the sprinkler piping network on certain preaction and deluge configurations. FireFlex documentation specifically notes this is useful where water leakage must be avoided during testing.
Choose it when:
- You want easier inspection and trip testing
- The project protects water-sensitive spaces
- The system type supports this option
Do not choose it when:
- The selected system type does not permit it
- The selected size falls outside option availability
Fire department connection
Meaning: This option provides a factory-prepared connection point so the fire department connection piping can be tied into the assembled unit.
Why it matters: It supports supplementary water supply from the fire department when required by the design or local code.
Choose it when:
- The project requires an FDC
- Local code, the AHJ, or building standard calls for it
- You want the unit factory-prepared for FDC piping tie-in
Important note
FireFlex documentation states that the fire department connection hardware itself is not included and is to be provided by the installing contractor.
