Wireless intruder detection system

The I-Beam IBD 300 is a standalone lithium battery powered system and a pulsed active infrared dual beam system.

The I-Beam detector transmitters (TX) and receivers (RX) are pre-mounted on heavy-duty anodised aluminium mounting poles. Each I-Beam type IBD 300 pole is powered by a single non-rechargeable lithium battery mounted within the connector block cover. A single core screened cable connects the last pole of the system to the ACP (alarm control panel).

The expected battery life in an I-Beam IBD 300 full pole is 12 months and in an IBD 300 half pole, 18-24 months. The I-Beam IBD 300 is a single zone multitransmitter/receiver system having dual beams in the same direction. Both beams need to be interrupted at the same time to trigger an alarm. The TX/RX housings are fully weatherproof and insect proof. It is not necessary to seal with silicone after installation.

The fully accessible TX and TX heads of the I-Beam system which are able to rotate horizontally and vertically, combined with a beam divergence resulting in a 2 m beam diameter at 30 m distance, permits quick and accurate visual alignment of the beams during installation and commissioning. The final beam alignment can be optimised from either the TX or RX ends of the beam using a standard multimeter and a temporary external 2-core cable before permanent locking of the TX/RX heads in their final set position.

The housings are fitted with a simple and secure alignment/anti-tamper locking system. Due to the innovative design of the TX/RX housings, the I-Beam system does not require heaters to prevent moisture fogging of the lenses.

The large 500 m spacing of the I-Beam upper and lower beams prevents false alarms caused by large debris, large flying birds, leaping cats etc. The blinding effect of sunlight especially at sunrise and sunset is substantially overcome by the automatic bias control of the I-Beam receivers.

The electronics of the I-Beam system has built-in lightning protection.

The I-Beam active infrared detection system is fully developed, tested and manufactured in the Republic of South Africa.
