Hard-wired Active Infrared Barrier
RANGE : 165 ft. (50) m to 656 ft. (200 m) outside
RELIABLILITY : Selectable channels, automatic gain control (AGC)
USER-FRIENDLY : Quick and easy installation, elegant design
Overview
The BIRIS II products are based on PROTECH’s expertise, offering multiple configuration possibilities.
The AGC guarantees detection reliability through 4 selectable channels to prevent interferences between barriers, and guarantee efficient operation of the system.
The BIRIS II barriers can be stacked on top of one another offering modularity to adapt to site requirements. Integrated alignment tools (audible and visual LEDs) make the products easy to install.
BIRIS II barriers are designed for both internal and external use in intrusion detection. The applications are diversified: protection of wall-tops, roof-tops, gates, building façades of small industrial sites and private villas.
Custom solutions are also available for specific applications such as roof edges, wall tops, and gates.
BIRIS II barriers are designed for internal and external use. The applications are, therefore, diversified: protection of or wall-tops, roof-tops, gates, building façades of small industrial sites and private villas.
Thanks to the modularity, easy and quick installation of BIRIS II barriers, it is also possible to secure sites with special installation and configuration (for instance, building roofs).
There are also very specific applications such as building façades, roof edges, wall tops, or gates.

Barriers must be installed on a stable support. Check that ground is level to ensure stability of the sensors over time.
A maximum of 10° elevation may be tolerated between the columns. In case of elevation above 10°, contact PROTECH’s sales department.
Beams must be free of vegetation coverage regardless of the season and weather condition (wind).
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 BIRIS II).
