Application Areas

The T4 Articulated Arm Plus Barrier is a cost-effective product used for controlling vehicle entry and exit, especially in low-ceiling indoor parking applications with medium traffic density.

Material

The T4 Articulated Arm Plus Barrier main body is manufactured as standard with electrostatic paint in RAL 3002 color code. The T4 Articulated Arm Plus Barrier model includes as standard: mounting apparatus, 4-meter arm, remote control, antishock rubber, reflective sticker, photocell, and barrier fork. Optionally, flasher, loop, button, heater and fan unit, and RAL color code option (available for orders of 5 units or more) can be provided.

General Use

The T4 Articulated Arm Plus Barrier is compatible with all access control systems such as remote control, button, card reader, and computer-based automation systems. With a daily open/close capacity of 1000 times, the T4 Articulated Arm Plus Barrier can also be opened manually in case of a power outage. When the access control device such as a remote, button unit, or card reader sends an open command via dry contact, the barrier system operates and the barrier arm opens. Meanwhile, the safety photocell mounted on the barrier body detects the vehicle passing under the arm and prevents the arm from closing on the vehicle in case of any delay. After the vehicle passes through the barrier, the arm automatically closes according to the automatic closing time. If the photocell fails to function properly while the vehicle is passing, and the barrier arm closes on the vehicle, the antishock rubber underneath the barrier arm will prevent damage to the vehicle and detect its presence, causing the barrier arm to reopen for safe passage.

Safety

The barrier arm, equipped with an encoder-based safe reverse mechanism, uses a photocell system to prevent the arm from closing in case of a possible delay during vehicle passage. Another method used is the loop system; when a vehicle arrives on the loop placed before the barrier, the loop sends a contact signal to the barrier and triggers the arm to open.
