RLS-2020 LiDAR fully compliant with Grade 3 criteria of European Technical Specification

Laser-scanning sensors, also known as LiDARs, have been a specific subject of the European Technical Specification, TS 50131-2-11:2017, that defines the functionalities and performance of Active Laser Detector responsive to Diffuse Reflection (ALDDR), to be used in security graded intrusion detection systems.

The Technical Specification (TS) – the latest preliminary stage for a new European standard, is a recognised criterion by PD6662:2017 in the UK, as well as in other national level security requirements of European countries. The Redscan RLS-2020 equipped with the latest firmware (version 2.1 and above) was tested by the VdS Schadenverhütung GmbH, a test house in Germany, and was certified as compliant with the TS as follows:

  • Laserscanner Grade 3 on the basis of CLC/TS 50131-2-11:2017
  • The device is suitable for use in intruder alarm systems according to EN 50131-1
  • The device complies with Environmental Class II of EN 50130-5

OPTEX’s RLS-2020 LiDAR units are an ideal solution for a number of indoor applications, such as protecting ceilings to detect intruders coming down through skylights, virtual fencing, high value assets in warehouses or shops, securing multiple paintings on a wall and loitering detection. Now, by being compliant to TS 50131-2-11:2017, RLS2020 can be added* directly onto a Grade 3 intrusion detection system; and can increase system performance by adding an extra level of security through functionalities that no other conventional indoor Grade 3 detectors (PIRs or dual-tech sensors) can provide.

*TS-specific installation instruction must be followed to meet the required grading criteria

BX Shield scores highly with leading security publication

The BX Shield series, our range of award-winning curtain outdoor motion sensors for intrusion detection, has become a recommended product by PSI magazine after scoring 8.5 out of 10 in a recent and fully independent product test report.

The PSI report assessed that BX Shield sensor is ‘a very straightforward alarm device with clear operation and simple set-up.’ The sensor reviewed was the BXS-AM, hardwired model with anti-masking, which is ideal to detect people in the immediate boundary of your home or office building.

One of the most appealing features reported on is the device’s design. Looking similar to some lighting units and available in white or black and white, the sensor is discreet and may not be immediately identifiable to potential intruders as an alarm device.

The report also praises the detection range of up to 12 metres on each side – giving a coverage of up to 24 metres in total. Left and right detection areas can be configured independently of each other to select sensitivity – from low to extremely high and detection range between 2.5, 3.5, 6.0, 8.5 and 12 metres. For enhanced flexibility, the rear mounting panel can be raised or lowered by 7mm, which gives an option to extend the detection area slightly away from the wall by an angle of 3°.

In terms of product performance, the report positively evaluates the detection system, which is able to ignore small to medium size animals and only detect people, achieved by a combination of a double layer of detection and specific detection algorithms.

Additionally, the BX Shield series provides a range of industry top security features that installers and customers value. These include an easy connection to a fixed dome CCTV camera to send a visual alarm when people are entering in the immediate boundary of the premises. Finally, the anti-masking feature available in the BXS-AM model provides a ‘trouble’ output if any objects had covered the lens.

About PSI Reports

PSI product tests are carried out by an independent third-party and provide a full review of product hardware, features, installation and performance. PSI (Professional Security Installer) is the only technical magazine in the UK circulated monthly, solely to installers, specifiers and designers of electronic security and fire solutions.

Tech Tip: Installation of a hybrid (wired/wireless) active infrared detection system

We offer a number of active infrared beam ranges but only the SL-TNR series offers hybrid power functionality, being part wired and part wireless. It is quite common to have sites where one infrared beam is close to a building with easier access to a power supply, while the other beam is located away from the building.

In such a scenario, previously two choices had been available: an ‘all wired’ solution where a cable needs to be run to both sides of a beam or an ‘all wireless’ solution where high capacitance lithium batteries are used to ease difficulties of the wiring.

The SL-TNR series that includes the SL-100TNR with 30m range and SL-200TNR with 60m range offers a third option which combines both choices; one side of the beam can be powered by batteries while the other side is powered through a cable, and additionally, you can still utilise signal radio transmitters.

What are benefits ?

  • No trench digging to run cables for the remote side of a beam
  • Reduction on battery cost
  • Flexibility to have wireless signal transmissions with wired beams

What do you need?

For a hybrid power setup, you will need a pair of SL-TNR beams which are battery-operated as standard and one OPTEX PCU-5, Power Converter Unit, available as an optional accessory.The PCU-5 will allow 12 or 24 VDC to be stepped down to approx. 3.9VDC which is required for SL-100/200TNR. Built with NO/NC relay terminals and a noise reduction circuit, PCU-5 can also bridge signals from SL-100/200 TNR over to security control panels.

In addition to the hybrid power setup, please let us also recommend BCU-5, Battery Common Unit, another optional accessory that enables a signal radio transmitter to harness power from, either hardwired (PCU-5 to be used) or battery-powered SL-100/200TNR.

Is your hybrid system connected to a wired or wireless alarm panel?

If the active infrared beam set is connected to a wired alarm panel, it might be best to hardwire the receiver beam and use the PCU-5 board to connect the relay outputs to the panel. As the low battery status on the transmitter beam will be signaled to the receiver beam via an infrared communication channel, you will only need to install a radio transmitter if you want to monitor the tamper of the transmitter beam.

If the beam set is connected to a wireless alarm panel, you can still decide to hardwire the receiver beam and insert a radio transmitter to communicate with the panel. If you need to monitor the tamper of the transmitter beam, a second radio transmitter will be needed.
If using a radio transmitter, BCU-5 is always a good option to consider regardless of being hardwired or battery-powered.


Active infrared beam sets perform best when the alignment is right, so don’t forget your voltmeter to achieve the best alignment.
