UL325 Entrapment Protection Requirements

Definitions

ENTRAPMENT: The condition when a person is caught or held in a position that increases the risk of injury.
SLIDE GATE ENTRAPMENT ZONE: An entrapment zone exists if at any point during travel, the gap between the gate and any opposing fixed edge or surface such as posts, walls, pillars, columns, or the operator itself, is less than 16″ (406 mm) in a location up to 6 ft. (1.8 m) above grade.
INDEPENDENT MONITORED ENTRAPMENT PROTECTION DEVICE: An entrapment protection device is independent if it is a different type (photoelectric sensors, edge device, inherent protection device) from the other devices in the same entrapment zone. Use the Site Planning Safety Checklist in the appendix to identify entrapment zones found in your installation.

Requirements

• A minimum of two independent monitored entrapment protection devices are required to be installed at each entrapment zone.
• It is the responsibility of the installer to install external monitored entrapment protection devices for each entrapment zone.
• The operator will only operate with a minimum of two independent monitored entrapment protection devices installed in each direction; two in the open direction and two in the closed direction.

This operator has an inherent entrapment protection device built-in. The installer MUST provide one additional entrapment protection device for each entrapment zone.
Acceptable entrapment protection device types include:

• Inherent (built into the operator)
• LiftMaster monitored external photoelectric sensors, see page 48 for acceptable sensors.
• LiftMaster monitored external edge sensors, see page 48 for acceptable sensors.

IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of INJURY or DEATH:

• READ AND FOLLOW ALL INSTRUCTIONS.
• NEVER let children operate or play with gate controls. Keep the remote control away from children.
• ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE.
• Test the gate operator monthly. The gate MUST reverse on contact with an object or reverse when an object activates the noncontact sensors. After adjusting the speed, force, or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of INJURY or DEATH.
• Use the manual release ONLY when the gate is not moving.
• KEEP GATES PROPERLY MAINTAINED. Read this manual. Have a Trained Gate Systems Technician make repairs to gate hardware.
• The entrance is for vehicles ONLY. Pedestrians MUST use a separate entrances.

Safety Installation Information

1. Vehicular gate systems provide convenience and security. Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application.
2. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. Gate systems design and installation must reduce exposure to potential hazards.
3. A gate operator can create high levels of force in its function as a component part of a gate system. Therefore, safety features must be incorporated into every gate system design. Specific safety features include:
   • Edges Sensors (contact)
   • Guards for Exposed Rollers
   • Photoelectric Sensors
   • Screen Mesh
   • Instructional and Precautionary Signage
4. Install the gate operator only when:
   • The operator is appropriate for the construction and the usage class of the gate.
   • All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 6 feet (1.8 m) above the ground to prevent a 2-1/4 inches (6 cm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position.
   • All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers.
5. The gate operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the pedestrian access such that persons will not come in contact with the vehicular gate during the entire path of travel of the vehicular gate.
6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening and closing to reduce the risk of entrapment.
7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.
8. Permanently mounted access controls intended for users to activate, must be located at least 6 feet (1.8 m) away from any moving part of the gate and where the user is prevented from reaching over, under, around or through the gate to operate the controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use. Exception: Emergency access controls only accessible by authorized personnel (e.g. fire, police) may be placed at any location in the line-of-sight of the gate.
9. For a gate operator utilizing a Stop and/or Reset button, it must be located in the line-of-sight of the gate. Activation of the reset control shall not cause the operator to start.
10. A minimum of two (2) WARNING SIGNS shall be installed in the area of the gate. Each warning sign is to be visible by persons located on the side of the gate on which the sign is installed.
11.  For a gate operator utilizing a non-contact sensor:
    •  See Install Entrapment Protection section for placement of non-contact sensor for each type of application.
    • Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving.
    • One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the perimeter reachable by a moving gate or barrier.
12. For a gate operator utilizing a contact sensor such as an edge sensor:
    • One or more contact sensors shall be located where the risk of entrapment or obstruction exists, such as at the leading edge, trailing edge and post mounted both inside and outside of a vehicular horizontal slide gate.
    • A hard wired contact sensor shall be located and its wiring arranged so the communication between the sensor and the gate operator is not subject to mechanical damage.
    • A wireless device such as one that transmits radio frequency (RF) signals to the gate operator for entrapment protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless device shall function under the intended end-use conditions.

Role of Dealers, Installers, and Trained Gate System Technicians

• Contact a trained gate systems technician to maintain and repair the gate system (End users should never attempt to repair the gate system).
• Retain and utilize the installation manual and maintenance and important safety instructions; see page 36.
• Routinely check all gate operator functions and gate movement.
• Discontinue use if safety systems operate improperly, the gate is damaged, or the gate is difficult to move. Contact trained gate systems technician to repair the gate system.
• Prominently display and maintain warning signs on both sides of the gate.

Site Preparation

Check the national and local building codes BEFORE installation. Refer also to the Site Planning Safety Checklist in the Appendix.

Safety
Entrapment protection devices are required to protect against any entrapment or safety conditions encountered in your gate application. Install a warning sign (two provided) on the inside and outside of the property, where easily visible.

Gate
Gate must be constructed and installed according to ASTM F2200 standards (refer to page 4). The gate must fit the specifications of the operator (refer to specifications).

**Additional Accessories

**

The vehicle loops allow the gate to stay open when vehicles are obstructing the gate path. Suggested for vehicles 14 feet (4.27 m) or longer. Vehicle loops are not required but are recommended. Before installing your Access Control Device(s) be sure to complete a site survey and determine the best device for your site needs.

CAUTION

• To AVOID damaging gas, power or other underground utility lines, contact underground utility locating companies BEFORE digging more than 18 inches (46 cm) deep.
• To prevent damage to the operator or gate, DO NOT drive the limit (nuts) actuators on the shaft past their normal positions.

Step 1 Install the Operator

Check the national and local building codes before installation. Install With Adjustable Rails

1. Locate and anchor two posts made of 3″ (7.6 cm) outer diameter heavy walled pipe. Posts should be parallel and square to the gate.
2. Locate electrical conduit, as required, prior to pouring concrete.
3. Slide the four 3″ (7.6 cm) clamps (provided) into the rails on the sides of the operator.
4. Slide the posts into the clamps and tighten the screws on the clamps to secure the operator.

Install Without Adjustable Rails

Check the national and local building codes before installation.
NOTE: The rails will have to be removed for retrofit installations.

1. Locate and anchor two posts made of 3″ (7.6 cm) outer diameter heavy walled pipe. Posts should be parallel and square to the gate.
2. Locate electrical conduit, as required, prior to pouring concrete.
3. Remove the rails from the sides of the operator.
4. Secure Operator to posts using four 3″ (7.6cm) U-bolts and hardware. The backing plate and gasket within the cabinet must be utilized with the U-bolts.
5. Fill any empty holes on the side of the operator with the extra bolts from the rails or apply a sealant.

Step 2 Attach the Chain

DO NOT run the operator until instructed.

1. Mount gate brackets to the vertical front and rear posts of the gate.
2. Open operator door.
3.  Locate the black T-shaped manual release handle attached to the gearbox at the bottom of the cabinet. Pull firmly until it latches into place.
4. Ensure that the drive and idler sprockets are in line with each other. Thread the chain through the plastic chain guide, around the drive and idler sprockets, and then through the second plastic chain guide toward front gate bracket.
5. Adjust the chain to the proper length and connect the chain to the front bracket with the provided hardware. Adjust nuts on-chain take-up bolts to remove chain slack. A general rule of thumb is to leave a maximum of 1″ (2.5 cm) of chain slack for every 10′ (3.1 m) of chain length. Do not overtighten chain. NOTE: The operator can be moved forward or back along the rails to ensure the chain is aligned correctly with the operator.
6. Remove the pin from the vent plug on the gearbox.
7. Push the plate down to release the manual release handle to re-engage the motor and gearbox.

WARNING

To prevent SERIOUS INJURY or DEATH from a moving gate:

• ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone.
• Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate.
• Entrapment protection devices MUST be located to protect in BOTH the open and close gate cycles.
• Locate entrapment protection devices to protect the moving gate and RIGID objects, such as posts, walls, pillars, columns, or the operator itself.

Step 3 Install Entrapment Protection

Definitions
ENTRAPMENT:
The condition when a person is caught or held in a position increases the risk of injury.

SLIDE GATE ENTRAPMENT ZONE:
An entrapment zone exists if at any point during travel, the gap between the gate and any opposing fixed edge or surface such as posts, walls, pillars, columns or operator itself, is less than 16″ (406 mm) in a location up to 6 ft. (1.8 m) above grade.
