LRM 8112 Movement Detector

Dimensions in mm

Definition

The LRM 8112 is a Movement Detector for the automatic control of lighting systems. It can be used in combination with various types of Philips Lighting Control Systems such as TRIOS

Description

• The sensor is intended for indoor use in an office environment and comes with a mounting ring for recessed mounting and a mounting plate for surface mounting.The unit is optimized for ceiling mounting.

• The pattern of sensitivity is nearly circular, covering an area with a diameter of approximately 8 m for tangential movements (i.e. around the detector) and approximately 6 m for radial movements (i.e. towards the detector). In the latter area most hand/arm movements will be detected.These figures apply to units mounted to a ceiling of between 2.6 and 3.0 m high.

• More movement detectors can be connected in parallel, in order to cover large or odd shaped rooms. One movement detector output can drive more controller inputs. For details refer to sections "Technical data" and "Miscellaneous".

• The movement detector has a built-in delay timer for the "inactive-state".

• By means of 3 dipswitches (5, 10 and 30 minutes) the timer can be set at values between 5 and 45 minutes. Setting all dipswitches to the off-position results in a walk-test mode with 0 minutes delay.

• The detector contains a red light emitting diode (LED), indicating the active state of the output.The LED can be disabled via a dipswitch.

• Dipswitches for timer setting and LED function can be reached via a hinged cover at the side of the unit. For access to the cover, mounted units must be disengaged from the mounting ring a few

centimetres.They can remain electrically connected and operational. Factory setting is: timer values off - LED on.

• The housing material is Polycarbonate, white (RAL 9010). It contains lens, sensor element and electronic circuitry and need not be disassembled during installation or commissioning.

• The Movement Detector is powered from the corresponding controller and does not require an external power supply unit.

• Electrical connections are made via a standard modular socket ("Telejack") using a separate sensor cable (not supplied with the unit).The "Telejack" entry is behind a hinged cover at the side of the unit. A cable duct with clamps is provided at the rear side of the sensor, allowing entry of standard flat oval cable from any direction when the unit is surface mounted.

• Recessed mounting in ceiling systems is possible without removing any ceiling parts, provided that sensor positions are pre-wired.The minimum recess clearance is a mere 60 mm.

• The LRM 8112 belongs to a series of sensors with identical construction and appearance. Other sensors in the series are a Light Sensor (LRL 8101), an Infrared Receiver (IRR 8124) and a Multi-Sensor (LRI 8133), i.e. a combination of the three sensor types.

- The LRM 8112 is a functional replacement for the phased-out types LRM 100 and LRM 8012.

Applications

• The Movement Detector is used in combination with TRIOS .

• Main application is energysaving by automatic switching of light sources, depending on the presence of persons in the room.
