The SPU.6-L is a sophisticated universal sensor which combines high performance presence detection, light level sensing and infra-red control into one compact unit.

Simmtronic has reacted to the current trend of narrower luminaires by introducing the SPU.6-L, a new linear narrow body sensor designed to be built into luminaires and track systems.

The SPU.6-L case is specifically designed to align with the common 30mm width of control gear (LED drivers). Provision is made for multiple method of fixing the case, top and bottom surface fixing points and provision for spring clip retention.

The sensor can either plug into an LCM’s DALI line or E-Bus from which both power and communication are achieved. The sensor automatically identifies itself on either bus and continuously reports its status and current readings. SPECS Manager software can uniquely address each sensor and configure each control element to different lighting groups as required. Photocell readings and presence detection history may be dynamically displayed for all sensors connected to the system.


  • Addressable Intelligent Universal Sensor
  • Luminaire mountable
  • 360-degree PIR presence detection
  • Wide range linear photocell
  • Programmable infra-red receiver
  • Flexible configuration via SPECS Manager graphical software
  • Simple E-Bus or DALI connection
  • Self-test LED indicator
  • Low profile compact design


“The device was conceived because our previous small PD became too big with the advent of slimmer LED lights. Architects want clean ceilings in exposed services projects and this new smaller solution fits into most light fittings as it is the same width as the LED Drivers within the light fittings. The unit was designed to be easy to fit with blanking plates, or incorporated in end plates in light fittings, with lots of mounting options provided to facilitate easy installation within light fittings,” said Simmtronic Sales Director, Mario Costanzo.

“Designed to fit into the RIDI pre-wired LINIA trunking system, this system is proving popular for CAT A office fit-outs and combined with Simmtronic’s solid presence in the commercial interior market, we believe this is a perfect solution for providing a fast fix lighting and control system,” said RIDI Managing Director, Michael Attard.

Simmtronic have delivered a large number of technically challenging projects for DBS and consistently continued to provide outstanding service. Their support, guidance and help throughout the process has been exceptional, working closely with our design teams to ensure the right solution for the project and a sound understanding of the brief, with our delivery teams to ensure the installation and commissioning are trouble free and then providing fantastic after care to the customer. They have added true engineered value into the projects they have been involved in for Derry Building Services.

Simmtronic have been a valued member of the DBS supply chain for over 10 years. Their pro-active and collaborative approach to lighting controls from the design stage, through to commissioning is highly valued by both our Design and Delivery Engineers.

Over the years I have really appreciated the Simmtronic ability to provide responsive support and listening to projects and clients needs. More recently the Simmtronic team has shown the capability to embrace the connectivity requirements of the Internet of Things by quickly adding MQTT to their range of integration protocols. This will greatly facilitate telemetry applications in buildings and the development of interconnected solutions that will make buildings more usable and easier to operate.

Landsec have consistently used Simmtronic Lighting Control Systems across our new London developments for over 15 years. Simmtronic understand our requirements and get involved at the very early stages of schemes, assisting consultants in achieving the optimum design solution, often taking the lead.  They always overcome the programme challenges they are faced with on site, delivering a quality, fully tested and operational solution, on time and to budget. Simmtronic undertake the maintenance and servicing across much of our London portfolio, they have a customer focused and flexible approach that suits the needs of our business and as well as our customers.

Simmtronic as an organisation has been, for the last 18 years, by far the best performing and most reliable lighting control system I use. From design through to commissioning and soft landings with the landlord teams Simmtronic always deliver on my projects. Simmtronic technology evolution is not just pushed through like others, but rather properly tested internally first, giving us as client teams the assurance that what Simmtronic say they can offer is 100% delivered, an absolute must with fast track major projects.

Simmtronic has constantly been available at an early stage to engage both with the designers and the Contracting team to assist with design solutions and to test options. This ultimately assists us in de-risking the project during the commissioning phase which usually defines when the project is completed. Simmtronic is seen as ‘industry standard’ and it is always encouraging to see them involved.
