Safety

The current UL-325 and ASTM safety standards that apply to your gate are too complex to describe in great detail. The following is a list of general specifications and requirements you need to know.

UL-325

CLASS 1 — RESIDENTIAL VEHICULAR GATE OPERATOR — A vehicular gate operator or system intended for use in a home of one to four single family dwellings, or a garage or parking area associated therewith.

CLASS II — COMMERCIAL/ GENERAL ACCESS VEHICULAR GATE OPERATOR— A vehicular gate operator (or system) intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units), hotel, GARAGES, retail store, or other building servicing the general public.”

CLASS III — INDUSTRIAL/ LIMITED ACCESS VEHICULAR GATE OPEATOR — A vehicular gate operator or system intended for use in an industrial location or building such as a factory or loading dock area or other locations not intended to service the general public.

CLASS IV — RESTRICTED ACCESS VEHICULAR GATE OPERATOR— A vehicular gate operator or system intended for use in a guarded industrial location or building such as an airport security area or other restricted access locations not servicing the general public, in which unauthorized access is prevented via supervision by security personnel.

Intended use of Alltec Gates & Operators — The Alltec 2100 Series Slide Gate Operators are intended for use with a vehicular horizontal slide gate on a Class I, II, III or Class IV installation. A vehicular horizontal slide gate is defined as any moving barrier that slides in the horizontal direction and is intended for vehicle use to enter a drive, parking lot or the like.

The Gate — The UL has defined four classes of gates that are specific to each type of facility. A self storage or rental apartment facility is defined as a Class II installation. See above for description.

UL-325 — 3.16 “COMMERCIAL/ GENERAL ACCESS VEHICULAR GATE OPERATOR—CLASS II— A vehicular gate operator (or system) intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units), hotel, GARAGES, retail store, or other building servicing the general public.”

REQUIREMENTS

1. The gate must be relatively smooth and free operating full open to full close.
2. The gate must be designed to travel level and not fall more than 45 degrees
   from plumb if it comes off of its rollers or wheels.
3. The gate, adjacent fence and support posts must be screened or guarded to
   prevent a 2-1/4” sphere from passing through at any point up to 4 feet high
   and a 4" sphere up to 6' high.
4. All wheels and rollers must be guarded to prevent a 1/4” rod from coming in
   contact with the wheel or roller.
5. The gate must be installed so the gate does not create an area of potential
   entrapment. This is more a common sense issue and is not specific.
6. Gate area must have a separate access point for pedestrians, such as a
   pedestrian gate.
   

The Operator (motor) — In a Class II Installation, the operator must have two anti-entrapment systems to prevent injury or death—a primary and a secondary. There are different types used by different manufacturers. Alltec Industries CS-2100 gate operators use a type A inherent (built in) obstruction sensor as the primary and is designed to accommodate a Type B-1 non-contact (photocell) secondary system.

OTHER REQUIREMENTS — all standard on the 2100 Series operators

1. Maximum speed of one foot per second.
2. A built-in manual disconnect to allow the gate to be moved independent of the
   operator in the event of an emergency or power outage.
3. Labeling to warn the user of the potential hazards of automatic gates.
4. Two warning signs to be attached to the gate to warn users of the hazards.
5. Complete instructions and safety information.

Controls — All controls must be far enough away from the automatic gate to prevent the user from coming in contact with the gate.

The UL and ASTM standards impact on the industry is not yet apparent because it, for the most part, has not become law. The insurance providers may start charging higher liability premiums to property owners if their gates are not up to safety standards. Alltec looks at this as both a challenge and an opportunity to produce the safest products and keep the cost down so it is not a financial decision on the part of the property owners.

Location

There are four things to consider when choosing a location for a slide gate:

1. The Space — Do you have enough room to slide it open & close it?
   A typical slide gate requires the size of the opening, plus 50% more than that to slide into. That means the overall space required is 2.5 times the gate opening.
    
   Example: A typical 17’ chain link gate needs 27’ to open into or an overall space of 44’. The Alltec Monorail 17’ gate needs 24’ to slide into or an overall space of 41’. We can fit a 17’ gate into a space as small as 22 foot’ with an overall space of 39’.
    
   NOTE: UL and ASTM safety standards require a separate access point for pedestrians so you want to consider at least 4’ extra for pedestrian access.

 

2. The Grade — To have a secure and efficient operating gate, you want it to be relatively close to the ground (3” to 7”). This requires a grade that does not vary too much from level at the gates location. A level grade at the gate closed position is good and it is OK to have that grade go down where the gate opens into. But, if the grade climbs where the gate slides open, you will have problems. One possible solution is to cut a trench for the gate to slide into. When possible, try to design and plan the grade for the gate.

 

3. Traffic Flow — When deciding the location for a slide gate, always consider its effect on traffic flow.
   
   1. The gate should be located as far from the street as possible. For self storage 40’ to 50’ minimum.
   2. Never force vehicles to turn through or into a gate. All turns should be far enough away so vehicles have a straight shot at the gate and its controls—in and out!
   3. Controls should be positioned for customer convenience and safety.


4. Parking — How do your prospective customers get to your rental office. If the
   parking is behind the gate, people who do not have access through the gate do not have convenient access to the Office and Manager. Customer parking is often overlooked — its not parking availability but the ability to get to the parking that counts. If parking outside the gate is not possible, then consider good and informative signage in conjunction with an intercom system. Most access control systems are available with an intercom system.

Electrical & Control Systems

Yes, automatic gates require electrical conduit and wired control systems. There are wireless systems and battery powered gate operators, all good, but generally much more costly and, in the case of controls, generally have much fewer operational features. If you are using wireless controls, consult with the manufacturer of the equipment.

Power — Gate operators require power to run. Typically electricity provided from your electrical panel. Even if you are considering the Alltec CS-2112 battery powered gate operator, you will still need to have a charging circuit and control circuit connected to it.

You must run a conduit from the power source (usually the electrical circuit breaker panel) to the gate operator location. This must be separate from low voltage control circuits such as keypad cables etc. Most localities require electrical license to perform this work. Be sure to meet all local and national electrical codes.

Controls — The keypads, card readers or even switches that open the gate need wires to the gate operator and the computers that run them.

You will need a conduit from each control location and from the computer location to the gate operator location. Remember to plan their location far enough from the gate (at least 4 feet) to prevent contact by the user with the gate.
