Residential
One-to-four single-family dwellings.
COMMERCIAL · INDUSTRIAL · HIGH-SECURITY
Commercial and high-security entrances require more than a larger operator. RADIUS coordinates gates, barriers, access controls, pedestrian movement, vehicle flow and service requirements.
01APPLICATION CLASS
UL 325 application classes describe the intended environment. They are not simply a ranking from least secure to most secure.
One-to-four single-family dwellings.
Multifamily, hotels, garages, retail and other public-facing sites.
Factories, loading docks and locations not serving the general public.
Restricted environments where security personnel prevent unauthorized access.
02LAYERED PROTECTION
Higher-security applications may combine individual credentials, event logs, cameras, vehicle detection, additional gates, bollards, turnstiles, emergency access and hardened approaches.
Crash ratings and hostile-vehicle protection are separate project requirements from the UL 325 operator class. RADIUS coordinates the appropriate manufacturer and security partners when those requirements apply.
Design the entrance around the threat, the traffic and the people who still need to use it.
THE HIGH-SECURITY PRINCIPLE
Separate pedestrian circulation from vehicular gates and create clearly defined visitor and emergency paths.
03SPECIALIZED SYSTEMS
Global GRAB and other qualified manufacturers offer active vehicle barriers and systems that can reinforce or integrate with existing gates. Ratings, foundations and controls must be selected for the project.
TYMETAL hydraulic rail-drive systems are examples of equipment listed for applicable Class III or IV applications. High speed does not remove the need for appropriate safety devices and controls.
Turnstiles, pedestrian gates and visitor areas should be separated from vehicular travel so people are not expected to use a vehicle entrapment zone.
RADIUS can coordinate physical gates and barriers with an existing building access-control provider, or help design an independent system when that creates clearer responsibility for the facility.

SECTION 11 / THE RADIUS GUIDE
The gate is one part of a complete physical and electronic security system.
People often call an automatic gate a security gate. In practice, the gate primarily controls who is allowed to enter and leave. The level of control comes from the gate, operator, access-control platform, vehicle detection, cameras, physical barriers, emergency access and the way the property manages those systems.
The four classes describe the intended application, not a simple ranking from “least secure” to “most secure.”
Residential applications associated with one-to-four single-family dwellings.
Multifamily properties with five or more units, hotels, parking garages, retail locations and other properties serving the general public.
Factories, loading docks and similar locations that do not normally serve the general public.
Restricted or guarded locations where unauthorized access is prevented by security personnel, including certain airport, government, military or critical-infrastructure applications.
The class identifies the operator’s intended application. Crash ratings, hostile-vehicle protection and other security specifications are separate project requirements. UL 325 entrapment protection and ASTM F2200 gate-construction requirements still apply according to the equipment, gate and site.
When a property needs more control, RADIUS may evaluate individual credentials, event logs, cameras, cellular or cloud management, vehicle detection, additional gates, bollards, turnstiles, hardened approaches and emergency-access systems.
Camera coverage over the gate can provide valuable context when a vehicle strikes a gate, a user reports being trapped or an access event is disputed. Cameras and logs support accountability, but they do not replace physical entrapment protection and an event log identifies a credential—not necessarily the person holding it.
RADIUS uses the ACCESS process to evaluate the property from the ground up: site needs, mechanical design, operator selection, construction, access control, safety, vehicle flow, emergency access and long-term service. The goal is an entrance that is safe, operational and maintainable—not merely a gate that opens.
Commercial, industrial, government and critical facilities may require separate pedestrian and vehicular circulation, visitor areas away from vehicle gates, turnstiles, controlled lanes, bollards, crash-engineered barriers or specialized hydraulic gate systems.
Global GRAB Technologies offers active vehicle-barrier and crash-engineered systems, including solutions designed to integrate with existing or new gates. TYMETAL offers hydraulic rail-drive systems listed for applicable UL 325 Class III or IV applications. These systems require project-specific ratings, site design, controls, safety devices and coordination with qualified manufacturers and security professionals.
Many older HOA and apartment systems have not been actively managed, depend on outdated telephone service or require a laptop to be connected at the entry panel. Some systems may be repairable or candidates for cellular and web-based modernization. RADIUS evaluates the model, power, wiring, service history, current usage and the owner’s desired audit trail before recommending repair, retrofit or replacement.
If a compromise or suspicious event occurs, preserve camera footage, access logs and credential records, then contact law enforcement or the appropriate authorities. Do not confront suspected individuals or alter evidence before authorities can review it. After that, contact the gate and access-control provider so credentials, programming, cameras, physical barriers and other safeguards can be reviewed.
If a system develops sequencing errors, unexplained movement, abnormal power behavior or repeated faults after an approved basic reset, stop relying on normal operation and request a professional assessment. RADIUS can train facility managers on manufacturer-specific controls and basic approved procedures, while ongoing user administration remains the property owner’s responsibility.
Look for a contractor who asks the right questions, understands the relationship between physical gates and electronic access controls, coordinates with existing security providers and can evaluate the full perimeter. A qualified team should be able to explain who owns each part of the system, how pedestrian and vehicle access are separated, how emergency responders enter and how the system will be maintained after installation.
ASSESSMENT & COORDINATION
RADIUS can perform a site security assessment, coordinate with architects and security professionals, and help facility managers understand who owns each part of the system.
Threat profile, traffic flow, pedestrian access, visitor handling, emergency response, power, communications, maintenance and long-term administration.
