FD-02 Quick-Fit Buckled Flood Door

Fast deployment for effective flood preparedness. Bolt-free clamps, modular aluminium panels and three-way EPDM seals simplify protection at building openings. The fully mechanical system is independent of power and supports a clear, repeatable deployment procedure.

Standard-opening deployment: ≈ 3 min
Trained deployment crew: 2 people
Special tools / deployment bolts: 0
Catalogue span without intermediate supports: Up to 4 m

Approx. 3 minutes applies to a standard opening, with two trained people and panels stored nearby. Actual deployment time depends on the configuration, access, storage and operator training. Permanent rails and anchorage remain part of the installation.

Its width/water-depth combinations must not be combined independently. The catalogue's “up to 4 m” span statement is not a blanket FM approval for every 4 m-wide or taller opening.

DEPLOYMENT DESIGN

Five features for faster, consistent deployment

FM Approved opening barrier

FM 2510 approval for opening barrier applications, Approval ID PR469796. Select the approved construction and dimensions for the project.

Rapid mechanical deployment

Two trained people deploy a standard opening in approx. 3 minutes with panels stored nearby. The system needs no electrical power.

Bolt-free clamping

No special tools or deployment bolts are required. Top compression and side clamps reduce loose parts and variation from tightening individual fasteners.

Horizontal panel insertion

Slide the panels into the rails from the installation side, layer by layer, without lifting them above the rail tops.

Modular span configuration

The catalogue describes spans up to 4 m without intermediate supports. Wider openings can use removable intermediate supports as configured; the approved width and water depth must be checked separately.

Bolted and clamp-lock barriers: common design differences

Bolted and clamp-lock barriers: common design differences
Feature	Bolted barrier	FD-02 clamp-lock system
Panel insertion	Panels are lifted above the rails and lowered into place.	Panels are inserted horizontally from the installation side.
Locking	Bolts are tightened individually, usually with tools.	Top compression and side clamps; no deployment bolts.
Deployment readiness	Tools, bolts and panels need separate checks.	Numbered panels and dedicated storage support quick retrieval.

Actual designs vary by brand, model and site conditions. Height increases require suitable rail provision and compatible panels; they are not an unrestricted upgrade.

APPROVAL AND TESTING

More than a hydrostatic-pressure test

The catalogue states that certification tests cover leakage, structural integrity, impact and durability. It presents a 120-minute full hydrostatic pressure test, leakage observed in testing ≈ 0, a 50 kg log impact and passed water-jet/durability tests.

Full hydrostatic pressure test: 120 min
Leakage observed in testing: ≈ 0
Log impact: 50 kg
Water-jet and durability tests: PASS

These are results reported in the supplied catalogue. “≈ 0 observed in testing” is not a zero-leakage guarantee under every site condition. The stated allowable leakage rate ≤ 1 L/h/m is a separate acceptance figure, not the measured total leakage of a door. Verify test and approval documents against the required flood head and installed configuration.

FD-02

Five-step deployment

Position the panels, apply top compression and engage the side clamps. No special tools or bolts are required for deployment.

01
Position the bottom panel
Place the dedicated bottom panel in position.
02
Insert the panels
Insert horizontally from the installation side and stack in sequence.
03
Temporarily secure
Use the side clamps to prevent the panels from moving.
04
Apply top compression
Press the top handles to apply vertical sealing pressure.
05
Complete lateral locking
Rotate the side clamps to complete lateral locking.

Critical facilities and a wide range of openings

Industrial and logistics roller-shutter openings

Data centers, electrical rooms and clean spaces

Loading bays and special openings

Pharmaceutical, food and precision manufacturing

Chemical storage, BESS containers and equipment openings

Wide-span entrances

Flood protection is selected against opening geometry, structural conditions, flood exposure, drainage and daily operation. Use around chemical storage or BESS does not itself establish fire, explosion or chemical-containment performance.

Flood readiness, from design to routine drills

01
Site survey
Opening dimensions, structural conditions, drainage and operating space.
02
System design
Configuration matched to flood protection height, opening width and site conditions.
03
Installation
Rails and seals, functional testing and documentation.
04
Operator training
Deployment, dismantling and storage procedures.
05
Routine inspection
Periodic checks and deployment drills to maintain readiness.

FAQ

FD-02: specification and deployment questions

What is the FM approval for FD-02?

The FD-02 Quick-Fit Buckled Flood Door has FM Approvals Class 2510 approval for Opening Barrier Applications, Approval ID PR469796, granted on 24 September 2024. The approved construction and dimensions must be checked in the current FM Approval Guide and the installation manual.

What approved width and water-depth combinations are shown?

The catalogue's Approval Guide table shows up to 1.8 m water depth with a 2.8 m section width, and up to 1.2 m water depth with a 3.9 m section width. The first configuration can use single or multiple sections, with intermediate supports for multiple sections. These are paired configurations; do not combine the maximum width of one row with the maximum depth of the other.

Does the up-to-4-metre span statement mean every 4 m opening is FM Approved?

No. The product overview describes a span up to 4 m without intermediate supports, while the reproduced FM table lists specific approved widths and water depths. Product span capability and FM approval scope are not interchangeable. Confirm the required width, flood head, supports and installation details for the project.

Can FD-02 always be deployed in three minutes?

The catalogue states approx. 3 minutes for a standard opening with two trained people and panels stored nearby. It is not a universal maximum time. Larger configurations, longer retrieval routes, access constraints and operator training can affect deployment time.

What does the catalogue's near-zero test leakage mean?

The catalogue reports leakage observed in testing ≈ 0 during a 120-minute full hydrostatic pressure test. It separately states an FM allowable leakage rate ≤ 1 L/h/m. A test observation is not a guarantee of zero leakage at all installations; acceptance should use the relevant documents, flood head, configuration and site sealing conditions.

Does deployment require power or lifting panels above the rails?

FD-02 is fully mechanical and needs no electrical power, special tools or deployment bolts. Panels slide horizontally into the rails from the installation side. Deployment then uses temporary side-clamp restraint, top compression and final side-clamp locking. Permanent rails and anchorage still require proper installation.
