LRM2070, LRM2080, LRM2090 Datasheet

General Description

The OccuSwitch DALI is a combined sensor and controller designed to dim and switch lights based on occupancy and available daylight. It offers options for local override, parallel operation, and network links to Building Management Systems (BMS). This system can achieve energy savings of up to 75% through features like daylight-dependent dimming, occupancy control, and over-dimension correction. The OccuSwitch DALI is suitable for office areas (20-25 m²) or classrooms (approx. 40 m²), with the detection area expandable using the LRM8118 extension sensor. It can control up to 15 drivers (luminaires). Installation is simplified by a detachable wiring connector and optional Wieland cables. Up to 22 advanced OccuSwitch DALI units can be linked in parallel for larger areas using a specific "open plan" mode. The LRM2090 integrates with most BMS and control systems via standard DALI interfaces (up to 64 units), enabling simple yet effective building control scenarios.

Applications

The OccuSwitch DALI is designed for offices, schools, corridors, and meeting rooms. It is optimized for recessed ceiling mounting at heights between 2.5 and 4 meters. A surface box is available for surface mounting. The advanced OccuSwitch DALI can be connected in parallel (up to 22 units) for larger open-plan offices, accommodating different mains groups or phases.

Features

Window/Corridor and Dynamic Offset Control

For optimal energy savings, window and corridor luminaires can be controlled separately. Window-side lights switch off (or do not switch on) when sufficient daylight is available. Corridor lights dim to a minimum, indicating system operation, or can be disabled. This feature can be turned off.

Energy Indicator

The LED on the OccuSwitch DALI changes color based on energy usage: green below 40% dimming, yellow below 70%, and red above 70%.

DALI Addressing

The OccuSwitch DALI supports one or two channels (window/corridor) for physical outputs (LRM2070 only), or DALI addressing for all versions. Up to 4 groups can be defined:

Additional luminaire groups can switch on with window/corridor groups or manually (absence). All groups switch off when the area is vacated. Pre-programmed luminaires are recognized on start-up.

Auto Commissioning

The OccuSwitch DALI can automatically determine the installed lux level and set it as the point for daylight-dependent regulation, eliminating the need for a Lux meter.

DALI Network Interface (LRM2090)

The LRM2090 features a second DALI interface (X connector) for connection to Building Management Systems (BMS) via a DALI gateway. It acts as a DALI slave, enabling functions like switching, dimming, scenes, and status queries. With a compatible gateway, parallel occupancy control similar to the advanced version is possible.

Commissioning Tool

The OccuSwitch DALI can be commissioned using the IRT9090 Extended IR programming tool. This tool allows setting light levels, starting walk test mode, assigning window/corridor functions, and configuring startup behavior, IR groups, and luminaire channels.

Walk Test Mode

The IRT9090 can initiate a walk test mode to quickly verify the correct installation and operation of the OccuSwitch DALI and connected luminaires.

100 Hours Burn-in

For fluorescent lamps, a 100-hour burn-in period is recommended to maintain light quality. The OccuSwitch DALI can automatically disable dimming functions during this period. Dimming is only permitted during walk tests and commissioning.

Extension Sensor (LRM8118)

The LRM8118 extension movement detector doubles the movement detection area and connects to the same DALI channel as the luminaires. It does not require a mains connection. Each LRM8118 counts as a DALI driver.

Push-button Unit (LCU2070)

The LCU2070 Push-button Unit (PBU) allows up to 4 switches to be connected to the OccuSwitch DALI for dimming and switching different DALI groups. It connects to the DALI channel (DA and/or X for LRM2070, DA only for LRM2080/LRM2090) and draws power from it. A short press toggles lights on/off; a long press dims them up or down. Up to two PBUs can be used per OccuSwitch DALI, and they can be interconnected. Each LCU2070 counts as a DALI driver.

Smart Timer

If minimal movement is detected, the standard delay time can be extended by 10 minutes automatically when movement is detected during the switch-off fade.

LRM 2090 - BMS Version

Response to DALI Commands

When a DALI command is received, all connected luminaires respond. Commands changing output levels disable daylight-dependent regulation while motion is detected. After the occupancy delay timer expires, daylight regulation resumes. A SCENE 1 command also enables daylight regulation.

Response to DALI Queries

The OccuSwitch DALI responds to DALI queries like a standard DALI driver. Queries on ACTUAL LEVEL return the average window/corridor value. Status and lamp failure queries report scan results. Other queries show stored values.

Parallel Mode

The LRM2090 supports parallel mode, allowing units to work together. Up to 64 LRM2090 units can be connected per DALI channel, forming up to 16 groups/rooms. Units react to movement detected by themselves or others in the same group. Modes 6 and 9 have specific linking behaviors.

Smart Open Plan (Mode 9)

In this mode, occupancy detection in neighboring units triggers lights to switch on at a background level. Only if the unit itself detects occupancy is the light set to the predefined level. Daylight regulation is active. Lights switch off only when no units detect occupancy and their timers have elapsed.

Advanced Functions for a BMS

The LRM2090 connects to BMS via DALI gateways. Supported gateways include:

• DALI <-> Lon (Loytec LDALI-3E10x)
• DALI <-> BACnet (Loytec LDALI-ME204)
• DALI <-> KNX (Philips PDBC120-DALI-KNX)
• DALI <-> DyNet (Philips Dynalite DDBC120-DALI-DyNet)

These gateways offer various functionalities and require separate DALI power supplies.

Integration with Occupancy

Gateways pass occupancy information to other systems (e.g., HVAC, sunblinds) at a group level, reducing bus traffic and simplifying commissioning.

Compatibility

Gateways support common integration tools like ETS, LNS™, LonMaker™, and Newron NL facilities™. The CEA-709 (Lon) gateway supports LonMark standards.

Exceptions

• SCENE 1 command initiates daylight regulation.
• Commands changing output levels restart the occupancy timer. Periodic re-issuance of commands may be needed to maintain light levels.

Addressing

OccuSwitch DALI supports standard addressing. Address commands are not relayed to drivers. The IRT9090 can set addresses (2-digit input) after clearing existing ones. The unit blinks LEDs to confirm settings.

Corridor Linking (Mode 6)

Units in corridor mode react to signals from their own group and adjacent groups. This keeps corridor lights on if occupancy is detected in nearby rooms, even if the lights are manually switched off or dimmed by daylight.

Energy Calculator (Loytec Gateways)

In conjunction with Loytec gateways, the OccuSwitch DALI can calculate energy usage. The gateway records dimming values and luminaire counts to provide energy consumption data.

HVAC and Blind Control (Loytec CEA-709 Lon)

Loytec gateways support a User Interface (UI) for controlling lighting, temperature, fan speed, and blinds via an infrared remote. This offers flexibility and user customization.

Mechanical Installation

The OccuSwitch DALI can be mounted recessed in the ceiling or surface-mounted using the LRH2070 ceiling box, which includes breakout ports for cables.

Electrical Installation

Installation can be done with conventional wiring or Wieland connectors (LCC2070/LCC2080). A detachable mains connector aids installation. The DALI signal is low voltage and isolated from mains, but all wiring should be treated as FELV (mains-rated isolation required). The network connection for LRM2080/LRM2090 also requires similar isolation.

Commissioning

Desired Standard Light Level

Three methods are available:

• Automated mode: Press button for 3s (yellow/green), release (red/green blink), clear area, auto-calibration starts within 10s. Lights flash to confirm success.
• Manual with normal control: Set desired light level via remote/switch, press button (yellow/green), clear area, light level after 10s is set point. Lights flash to confirm success.
• Manual with IRT9090: Use up/down keys to set level, press "SAVE". Lights flash once to confirm success.

Delay Time Occupancy Control

A rotary dial allows selection of delay times: 70s, or 5 to 30 minutes (in 5-minute increments).

Further Commissioning (IRT9090)

The OccuSwitch DALI acknowledges commands by flashing lights. The IRT9090 has a narrow beam for precise targeting within 17 meters.

Settings Done by IR Remote

Settings are sent with the green SEND button. The red LED on the transmitter indicates function selection.

Change IR Group

OccuSwitch DALI and transmitters operate in 7 groups (A-G). Both must be in the same group.

Change Power-up Behavior

By default, output is ON when mains connected. Lights switch off after 5 minutes if area is vacated. Option to leave output OFF and start movement detection 30 seconds after mains connection.

Restore Defaults

Aim IRT9090 at OccuSwitch DALI, press "reset", then SEND.

LED Indicators

Error States

In case of failure, the OccuSwitch DALI aims to maintain a safe situation, either by operating "as good as possible" or switching lights ON. The LED will be permanently yellow if the device or its peripherals fail, even without movement or communication.

OccuSwitch DALI Modes

The OccuSwitch DALI offers various modes for different applications, selectable via the IRT9090 tool. These modes are stored in non-volatile memory.

Mode Overview

• Mode 1: Cell office, Auto on
• Mode 2: Open plan office, Auto on
• Mode 3: School, classroom, Manual on
• Mode 4: Cell office, Comfort mode (EN 12464)
• Mode 5: Open plan office, Comfort mode (EN 12464)
• Mode 6: Corridor, Auto on
• Mode 7: Toilets, Auto on, DDR off
• Mode 8: Meeting rooms
• Mode 9: Open plan, Always light, Auto on (works differently for LRM2080/LRM2090)
• Mode 10: Open plan, Comfort mode, always light, Custom mode

Mode Parameters Table

* Equals mode 1 and 2, but without MD active. Do not use these modes for normal applications.
** This mode works differently for the advanced (LRM2080) and network (LRM2090) OSD when compared with OSD basic (LRM2070). For LRM2080 & LRM2090 the lights will switch off (the basic never switches off) when none of the advanced OccuSwitch DALI units in the parallel network detect movement. If one or more do detect movement, all other units will go to background level.

Safety

The OccuSwitch DALI uses DALI signals. Interfaces (DA and X) have additional isolation from mains (SELV). However, DALI devices (like drivers) often have basic isolation only. All interface wiring should be treated as FELV, requiring mains-rated isolation to prevent unsafe installations.

Short Circuit and Protection

The DA and X interfaces provide DALI power and are protected against short circuits within specification. External DALI power supplies are for the LRM2090's BMS DALI network (X-interface). Connecting more than 22 LRM2080 units in parallel on the X-interface can damage it. The LRM2090's network (X) interface has extended protection. Connecting mains power to the DA or X interface (except LRM2090 X-interface) will cause irreparable damage.

Parallel Mode (LRM2080)

The LRM2080 supports parallel mode for occupancy control via the X-interface. Units share the MD signal, meaning lights stay on if any connected system detects movement. Lights switch off or go to background level only when the last MD timer elapses. Mode 9 is an exception, with a 60-second refresh for the parallel link.
