How to Install FreeDoor 2.4.6.8
Maintaining strict fire door safety compliance while allowing free, unhindered movement within a building is a major operational challenge for modern facility managers. Standard door closers create continuous heavy resistance, making passage difficult for individuals with mobility challenges, elderly residents, or staff carrying equipment. Holding fire doors open with traditional wedges or makeshift heavy objects violates strict fire safety regulations and building compliance standards.
The FreeDoor system (specifically modeled around multi-size power systems such as standard EN 2, 4, 6, and 8 door sizes or versions like FreeDoor 2.4.6.8) resolves this conflict. Operating on acoustic and wireless sensing technology, it holds fire doors open at any desired angle during normal operations without imposing spring tension. When a fire alarm sounds, the system detects the acoustic signal or radio trigger and automatically disengages the hold-open mechanism, ensuring the door closes securely into its frame to preserve compartmentation.
Understanding how to install freedoor2.4.6.8 correctly ensures full regulatory compliance, flawless acoustic alarm reaction, and long-term durability. This guide provides an end-to-end walkthrough covering pre-installation site checks, step-by-step physical mounting, logic configuration, testing, and preventive maintenance.
Pre-Installation Assessment and Tools Required
Before initiating the physical installation process, complete a site survey to verify that your door assembly meets all technical prerequisites.
Door Leaf & Frame Inspections
- Door Width and Weight: Ensure the door leaf does not exceed maximum allowable dimensional and mass boundaries (typically up to 950 mm width and 60 kg weight for standard units).
- Structural Soundness: The top rail of the door leaf and the upper door frame lintel must be free of rot, cracking, or hollow voids. Timber screw fixings must achieve full thread depth into solid wood or reinforced masonry anchors.
- Latch and Hinge Smoothness: Test the door manually without any closer attached. The door must swing smoothly through its entire arc without binding against the floor carpet, frame jamb, or weather seals.
Essential Tools and Equipment
Gather the following tools prior to starting:
- Cordless drill with 3 mm wood bit and 6 mm masonry bit sets
- Spirit level (300 mm minimum length)
- Tape measure and marking pencil
- Screwdriver set (Pozidriv PZ2 and flathead precision drivers)
- Manufacturer alignment template (included with unit kit)
- Sound level meter or acoustic calibration app
- Personal Protective Equipment (PPE: eye protection and dust mask)
Safety Requirements and Building Compliance Standards
Fire door hardware installation is governed by strict regulatory frameworks. Failing to follow accurate installation steps can compromise your building’s fire safety envelope and void insurance coverage.
Key Regulatory Standards
- BS EN 1154: Governs mechanical door-closing devices, evaluating durability, closing force, and speed control.
- BS EN 1155: Covers electrically powered hold-open mechanisms, requiring automatic release upon power failure or fire alarm activation.
- BS 7273-4 (Category B): Specifies standards for fire door release mechanisms activated by acoustic sensors or radio frequency signals.
Safety Warning: Never install acoustic or wireless door release units on external weather doors, fire doors exposed to continuous background noise exceeding 80 dB(A), or doors equipped with emergency panic escape hardware unless explicitly certified by the manufacturer.
Orientation and Mounting Position Selection
Determining the exact mounting location is critical before drilling any pilot holes. The FreeDoor 2.4.6.8 unit supports four main configuration layouts depending on swing direction and room architecture.

| |
+—————————————————————–+
Pull Side (Standard Door Mounting)
The main unit body mounts directly onto the pull-side face of the door leaf, near the upper hinge edge. The guide arm attaches to the overhead door frame. This orientation typically limits the maximum swing angle to 105 degrees.
Push Side (Transom Mounting)
The main unit body mounts onto the transom header frame above the door leaf on the push side, while the arm shoe attaches to the door face. This layout provides wider clearance up to 135 degrees.
Mounting the Base Plate and Closer Body
Once the mounting position is determined, proceed with securing the main structural components.
Step 1: Position the Drilling Template
- Align the manufacturer paper template against the top edge of the door leaf on the hinge side according to your chosen orientation.
- Use a spirit level along the horizontal top guide line of the template to ensure perfect levelness.
- Secure the template with masking tape.
- Mark center points for all fixing holes using an awl or center punch.
Step 2: Drill Pilot Holes and Secure the Plate
- Remove the paper template.
- Drill pilot holes to a depth of 35 mm using a 3 mm drill bit to prevent timber splitting.
- Align the heavy-duty steel backplate over the drilled holes.
- Fasten the backplate securely using the provided high-tensile wood screws. Ensure all screws are fully seated without stripping thread channels.
Step 3: Attach the Closer Engine
- Hook the upper edge of the FreeDoor main body onto the top flange of the installed backplate.
- Pivot the unit downward until the lower retention clips click into place.
- Fasten the lower locking screws using a PZ2 screwdriver to secure the housing.
Arm Assembly and Track Channel Alignment
Proper arm connection ensures smooth free-swing motion and full closing force transmission when triggered.
Step 1: Install the Overhead Track or Shoe
- Place the track mounting template on the door frame header lintel.
- Verify clearance distance between the arm pivot hinge and the frame jamb.
- Drill pilot holes and screw the mounting shoe securely into the frame structure.
Step 2: Connect the Free-Swing Arm
- Fit the main closer arm onto the bottom drive spindle of the FreeDoor body.
- Tighten the central spindle retaining bolt to the specified torque value (typically 8–10 Nm).
- Extend the sliding arm link and insert the roller slider block into the track channel.
- Install end caps on the track channel to keep the slider block securely inside the track.
Electrical Supply and Battery Pack Installation
The FreeDoor 2.4.6.8 unit uses an internal high-capacity alkaline or lithium battery pack, eliminating the need for complex, costly mains cabling.
