We spoke to Dan Pahal, Business Development Manager at GfA UK, to discuss how installers can navigate these complex specifications.
For installers and specifiers, success lies in asking the right questions at the outset. Traffic levels, security, user profile, noise sensitivity, and system integration all influence the correct choice of drive and control package. Get it right, and the result is a high-performing, low-maintenance solution that satisfies end-users, architects, and facilities managers alike.
Understanding traffic demands
The starting point for any car park project is usage. A simple way to estimate demand is to multiply the number of parking spaces by the expected turnover. In busy retail environments, entrances and exits may operate almost continuously at certain times of the day, whereas residential or commercial settings may see distinct peaks in the mornings and evenings.
High traffic volumes demand drives designed for frequent operation and minimal downtime. Underspecifying here risks premature failure of the drive system requiring costly callouts. For these applications, a high-usage, or GfA FI (inverter) drive is often the required solution to handle the duty cycle.
Managing noise and neighbour impact
Noise is frequently the deciding factor in residential and mixed-use projects. A door that rattles, slams, or lingers open can quickly generate complaints from occupants above or beside the car park.
Selecting an FI drive with soft-start and soft-stop functionality significantly reduces mechanical shock and vibration. Inverter drives allow for smoother acceleration and deceleration, improving both acoustic performance and component longevity. While lath type and mounting arrangements are critical to minimising transmitted vibration, the control logic must also be set to avoid unnecessary open times that prolong the disturbance.
Specifying for public use
Unlike industrial sites, many car parks are used by untrained members of the public, which changes the safety equation. Automatic operation, vehicle detection loops, photocells, and safety edges are essential considerations.
Clear logic that ensures the door closes promptly once a vehicle has passed improves both safety and security. Specifiers should refer to BS EN 12453 5.2.1.8 [AC1] to help select the correct type of safety devices for the application.
Where a punched lath or rolling grille is utilised, high-level anti-entrapment sensors must be installed if there is risk of a person being lifted by the door. Installers should also consider control panel accessories, such as blanking plates and safety edge covers, to prevent unauthorised use and vandalism in accessible areas.
Intelligent control and integration
Today’s car-park doors are no longer simple open-and-close mechanisms; they are active parts of the building’s ecosystem.
Integration is increasingly important. In enclosed or underground facilities, doors often need to link with fire-alarm systems, ventilation fans, or building management systems (BMS). The control solution must accommodate these additional signals without compromising reliability.
This orchestration requires a control solution with sufficient inputs and outputs, as well as sufficient flexibility. Functions such as auto-close (triggered once a vehicle clears a detection beam) help prevent doors from remaining open unnecessarily. In ramped or narrow entrances, traffic-light sequencing can manage one-way movement to reduce conflict, while exit stacking management prevents vehicles from queuing out into public roads.
Security beyond the door leaf
Car-park entrances pose a specific security risk, meaning specification must look beyond the door leaf. Whether linked to access cards, remote controls, or ANPR systems, the control panel must integrate seamlessly with external inputs.
Specifiers should consider the logic for both directions. How is unauthorised access prevented on entry? How is tailgating managed to ensure security without causing congestion on exit?
Security also means resilience. Rapid closing after activation reduces the window of vulnerability and discourages misuse.
Checklist: Selecting the right package
When specifying a drive and control solution for a car-park project, a structured checklist helps avoid compromise:
● Cycle rating: Confirm the number of spaces and cycles per hour/day to ensure the drive rating matches the application.
● Door type: Roller shutters, sectional doors, folding gates, and sliding gates all require different drive configurations.
● Speed and smoothness: In busy environments, faster opening reduces vehicle waiting times, but this must be balanced with controlled, quiet movement as with the GfA FI drives.
● Control capability: Ensure the control panel can handle the required peripherals. The GfA TS Control Panel range, for example, is available with 1000mA support to accommodate the additional 24v loading from ancillary devices like traffic lights.
● Safety and security: Specify safety edges, monitoring systems, and anti-entrapment devices.
● Environmental conditions: Consider IP ratings and protection based on where the drive and control are being installed.
Long-term performance
Ultimately, car park access systems are judged on reliability. Facilities managers expect consistent performance with minimal disruption, while residents notice only when something goes wrong.
By carefully assessing traffic levels, user profiles, and integration requirements at the specification stage, installers can match the correct drive and control logic to the application. The result is a solution that delivers smooth operation, strong security, and low noise, even under demanding conditions.
