How it works
A typical access sequence depends on the controls and vehicle-detection equipment specified for your installation.
The driver approaches the designated vehicle lane and stops at the control point.
An operator uses the supplied remote, or a compatible access system sends an approved opening command.
The barrier returns to its closed position according to the configured controls. Confirm vehicle detection and closing safeguards in your installation scope.

Practical answers for planning a GS-819-R installation.
The GS-819-R is an automatic boom barrier with an L-bend retractable arm for controlling vehicle entry and exit where overhead clearance is limited. It supports brushless, DC, AC and servo motor options and boom lengths up to 6 metres.
The GS-819-R can be supplied with a brushless, DC, AC or servo motor for safe, efficient barrier movement. Share your traffic volume, operating speed and power supply details with our team so we can recommend the right motor for your site.
The arm folds vertically as it opens instead of rising as a single straight boom, reducing the overhead clearance required. Measure the available height at your entrance and share it with our team to confirm the configuration.
The catalogue lists an adjustable opening/closing time of 1.5–3 seconds. Confirm the appropriate setting for your boom length, traffic flow and site safety requirements during configuration.
The housing is rated IP54 for protection against dust and water splashes, with a listed operating temperature range of −35°C to +65°C. Installation should account for local exposure, drainage and the electrical supply.
The listed configuration includes two remote controls with a range of up to 30 metres. Actual range depends on the installation environment.
Share your RFID, ANPR or access-controller details with our team. Controller interfaces, triggering requirements and any additional equipment need to be checked before compatibility can be confirmed.
Boom configuration, quantity, access-control equipment, vehicle detection, civil works, wiring and installation location all affect the quote. Ask for an itemised proposal that confirms supply, installation, warranty and service coverage.
If the entrance has clear overhead space, the GS-819-SL telescopic model offers a straight arm for lanes up to 6 metres with adjustable 1.5–3 second operation.
