2. Automatic Sliding Door Overview

Terra's automatic sliding doors are ideal for high-traffic areas and are intended for use in positive or negative-pressure cleanrooms where air movement is acceptable. They include either an external or recessed mount with automatic or manual operation.

External-mounted doors are well-suited for retrofit construction whereas recessed doors are ideal for room partitions or openings larger than the desired door size. They are available in aluminum or stainless steel frames with either tempered glass or static-dissipative polyvinyl chloride door panels. Doors include load-bearing wheels made of cast urethane for long-lasting, smooth, and trouble-free operation. Terra has specially designed its doors pre-hung to frames to allow quick, seamless, and non-intrusive installation

2.1 External Mount Doors Overview

The door track is mounted externally to the wall surface and is well suited for retrofit construction and easy installation where a large opening is not possible for recessed door frames. The system requires enough empty wall space next to the opening to allow door(s) to slide completely open.

The microprocessor controller continually monitors door position with adjustable features such as:

  • Opening and closing speed.
  • Distance and speed of braking.
  • Reducing opening and time delay.

The unit arrives with the pre-assembled header and panel sub-assemblies. The adjustable anti-rise wheels lock each door in its overhead track and undergo life testing to a minimum of one million cycles.

Manual External Mount Cleanroom Doors

Manual external mount doors use 304 stainless steel and include left or right sliding options as well as load-bearing wheels made of cast urethane for long-lasting, smooth, and trouble-free operation. 304 Stainless steel stands up to common disinfectants and the door assembly includes the frame and track that are installed inside the existing wall cutout/partition.

For strict cleanliness protocols, BioSafe® windows forego shoddy spot-welding in favor of dual-pane glass installed flush on steel for a continuously smooth surface. The wall cut-out size for the doors should be at least 81” in height and 36” width.

Automatic External Mount Sliding Doors include adjustable anti-riser wheels that lock each door in the overhead track as well as auto reverse and slow speed search for obstruction. The elastomeric door seals and fiberglass reinforced timing belt ensure cleanliness, durability and uniform closing. All automatic doors use the hand wave sensor to open the doors and the ESA II Revive kit to prevent the door from closing on someone when that person is entering or leaving. Static dissipative PVC door panels enhance static and particle control, stand up to cleaning agents, minimize obstructive sight line and reduce claustrophobic sensation in small rooms. These doors are ideal for aseptic cleanrooms that require hands-free door operation available with several different styles.

2.2 Pre-hung Recessed Doors

The door frame and track are installed inside the existing wall cutout/partition with a touchless motion door pad for hands-free operation. These doors are well-suited for room partitions or openings larger than desired door size and can be configured to include side lights for additional visibility. The toothed drive belt reinforced with fiberglass prevents slippage and ensures even closing. These doors arrive with a pre-assembled header and panel sub-assemblies.

  • Recessed doors use an Optex X-Zone T sensor for door operation and a single-point bottom rail deadlock(s) electric locking. Manual recessed doors include left/right sliding options and are pre-assembled.
  • Doors purchased prior to March 2019 use a Stanley SU-100 motion sensor or Stan-Guard® Threshold sensor.

3.3 Sliding Door Interlock Install

Install the interlock box on top of the ceiling and between the doors that will be interlocked.

Verify that the cables from the doors and E-stop will reach the installation location with a minimum of 2” of slack.

Twist the quick connectors on the ports on the interlock box without straining the cable ends.

Plug the interlock box’s power cable into a 120V / 60 Hz compatible outlet.

Find a suitable location for E-Stop that is easily accessible in an emergency situation.

Attach the quick-connector(s) from the door’s electromagnetic locks and E-stop to the interlock box.

  • Verify the connectors are attached to the correct ports by their label identification.
  • Wrap up extra cables length leaving the minimum 2” slack.

4. Cleanroom Interlock Operation

4.1 Door Interlock Operations Overview

Terra's door interlock box will prevent interlocking doors from opening at the same time by using a small sensor, located on the upper region of the door, to communicate back to the interlock box. The sensor is used to determine which doors are open and which doors are closed so the interlock box can keep other doors closed when an interlocked door has been opened. The interlock box will send a signal to the interlocking door's operator to keep the door closed which reduces cross-contamination. Pull and twist all E-Stops to disengage them and verify that the interlocking system is operational after installation.

Interlock Door Testing

Test the interlocking mechanism by opening one of the interlocking doors and having another person try to open the other interlocking door. The second door should remain closed; if this is not the case, please refer to the troubleshooting section.

Emergency Operations

Safety: In the event of an emergency, the E-Stop can be pushed in to disable the interlocking. This will allow interlocking doors to open at the same time to aid in evacuation. When the door includes an automatic door closer, the interlock box will prevent the sensors from detecting and powering the motor and allow the doors to be pushed open at the same time with approximately 20lb of force

4.1.1 Door Interlock Specifications

  • Voltage: 120V, 0.5Amp, 50/60 Hz
  • Dimensions: 11”L X 6”H X 15”D
  • Weight: 5 lbs

4.1.2 Door Interlock Troubleshooting

Warning: Disconnect the power supply before inspecting the fuses.

Inspect the two fuses that protect the interlock box:

  • The first fuse is for the high-voltage main line and the other fuse is for the low-voltage DC supply.
  • Verify the fuses are not burnt out. If they are, replace the broken fuses with the same rated fuse.

Check that the E-Stop is not pushed in and engaged.

  • Pull and twist the E-Stop to disengage.

Verify all cable connections are fitted properly to the interlock box.

  • Remove the quick-connector(s) from the interlock port and check that the quick-connector’s pins are not bent or broken; repair if necessary.
  • Reinsert the quick-connector and twist clockwise to lock the connection in place.

Verify the door’s operation mode is set correctly.

  • The switches are located on the left side of the upper housing.
  • Set the main switch to AUTO and the other switches to OFF position.
