Infrared technology for gates
APPLICATION : Using PORTALIS as a G-FENCE system accessory for gates
INNOVATION : Solar powered solution
HIGH PERFORMANCE : B Beams multiplexed through optical synchronization
PORTALIS is an infrared solar-powered barrier that is connected to a G-FENCE system to provide perimeter intrusion detection on gates. G-WALL creates an invisible/virtual wall of detection with five dual-beam cells at a height of 8 ft. (2.5 m) or 10 ft. (3 m) depending on the gate being protected.
Beams are multiplexed through optical synchronization and can be set-up in single or dual detection mode with adjustable heights.
PORTALIS has four alarm information modes: intrusion, anti-climbing cap, tamper, disqualification (technical alarm). Alarm information is relayed through polarized contacts to the auxiliary inputs of a nearby G-FENCE Control Unit.

Ensure Portalis is not installed on where unstable support exists (e.g. poorly sealed pole, etc.).
Check that the ground is level and will ensure stability over time. A maximum of 10° elevation may be tolerated between the columns. In case of elevation above 10°, contact PROTECH’s sales department.
Check that vegetation will not cover the system, regardless of season and weather conditions (wind).
Ensure covers are kept clean: it is important to clean them with a soft and damp cloth at least annually.
Infrared technology operates at a wavelength above that of visible light (950nm), which makes the IR beam invisible to the naked eye.
IR beams are transmitted and received by infrared cells – transmitter cells generate and send a pulsed beam to the receiver cells which capture infrared pulses and turn them into electrical signals. When an absence, loss or change in the signal occurs (loss of 95% of the transmitted signal), an intrusion alarm is triggered. To prevent interference of receiver cells by the infrared beams being transmitted, cells are multiplexed.
Multiplexing is a principal whereby infrared pulses are transmitted in a synchronized manner by an optical or wired link between transmitter and receiver columns. This feature optimizes cell alignment (“alignment feedback”). All the PROTECH IR barriers are multiplexed (except UNIRIS II & BIRIS II).
