Smart motion and light sensor

• Function description

  The SENPreLi is a discrete, white, round presence sensor equipped with 2 sensors that detect movement and light intensity (lux). You can also use a night function where the dimmed light circuit turns on at a lower intensity. This day-clock function can be activated via time schedules, logic, or standard operation.

  The product is suitable for indoor ceiling installation. You can connect this sensor directly to the Qbus two-wire bus using the provided flexible connection cable. Configuration is done via System Manager III.

  The SENPreLi, like every Qbus module, has a unique serial number (prefix 0058) that is entered during configuration in the System Manager III configuration software. The programmed data is stored internally in permanent memory. This sensor can receive firmware updates via the Qbus bus.

  The sensor can directly control various I/Os based on these sensor values:

  • Presence: The sensitivity has two levels. There is an adjustable sensitivity threshold for presence detection to activate the I/O via an “Activation trigger,” and to keep the I/O on, a lower presence threshold is adjustable with a “Retention trigger.” The delay time for when presence is no longer detected and the I/O must be turned off is adjustable between 2 seconds and 127 minutes. You can visually test the current presence detection using a scan function. Once the presence detection goes below the yellow line (retention), the delay time starts.
  • Lux: Threshold >= or <= adjustable between 0 and 3000 lux.

  The I/O to be controlled can be of the Bistable or Dimmer type. Therefore, the sensor can directly control a dimmer based on lux measurement and presence detection.

  A blue indicator LED is provided for displaying presence detection.

General

• Safety regulations

  Read the full manual before installing and activating the module.

  ATTENTION

  • The module must be installed, commissioned, and maintained by a certified electrical installer in accordance with the applicable legal regulations of the country.
  • Before working on the SENPreLi, the bus power supply must be turned off.
  • Never connect external voltages (e.g., 230Vac) to the Qbus bus! This will cause irreparable damage to the modules.
  • Keep out of reach of children.
  • The module must not be opened. The warranty is void if the module is opened!

Installation and wiring

• Installation

  For the recessed version, prepare a circular opening ideally measuring 40, 44 or 48 mm. Connect the supplied cable to the bus cable. Then push the connections in sufficiently so that the sensor has enough free space. Open the spring clips and, without applying excessive force, insert the sensor into the opening. Do not press on the sensor during installation.

• Power supply

  The module is powered via the bus.

• BUS connection

  It is recommended to use the Qbus cable or any other cable with a minimum of 2 conductors of 1mm² as the bus cable. The green shielded EIB cable can also be used if the conductors are paired to achieve a minimum cross-section of 2 x 1mm².
