Applications and Detection
The OccuSwitch is designed for offices and similar applications like toilets and storage rooms. It is optimized for recessed ceiling mounting at heights between 2.5 and 3.5 meters. A surface box option is available for surface mounting, accommodating recessed wiring or surface-mounted ducts.
The advanced OccuSwitch (LRM1080) can be connected in parallel (up to 10 units) to cover larger areas such as open-plan offices, and it supports different mains groups or phases.
Detection Pattern:
- For minor movements (e.g., desk work): 4 meters by 5 meters.
- For major movements (e.g., walking): 6 meters by 8 meters.
The diagrams illustrate these detection zones and typical placement for standard and parallel operations.
Functions
Daylight Control
- Daylight Override: Prevents lights from switching on when sufficient daylight is available, enabling additional energy savings.
- Daylight Switching: Actively switches lights off when sufficient daylight is present and turns them back on when light levels drop. This function requires the DIP switch to be ON and the light level to be set. Lights switch off if the level is above 220% for over 15 minutes, and switch on when the level drops below the required level.
Advanced Version Functions
- Parallel Operation: Up to 10 OccuSwitches can be connected in parallel via a bus signal. When one unit detects movement, all connected units switch on the lights. The bus signal is isolated, allowing use across different mains groups or phases.
- Local Override: Allows overriding automatic operation with a remote control, for instance, to switch lights off even if movement is detected.
- Absence Mode: When enabled via remote control, the OccuSwitch will not automatically switch lights on when people enter the area. Lights switch off 1 to 30 minutes after the area is vacated.
General Functions (Both Versions)
- Automatic Control: Lights switch on automatically upon movement detection and switch off after the area is vacated (delay adjustable from 1 to 30 minutes).
Features (Both Versions)
- Smart Timer: Extends the switch-off delay by 10 minutes if movement is detected shortly after the lights turn off, assuming the area is still in use.
- Shield: A retractable shield can be used to mask off adjacent areas like corridors.
Features (Advanced Version)
- Remote Tool (IRT9090): Enables changing light level settings and power-up behavior without direct access to the unit. It can set the OccuSwitch to not switch on at power-up, starting detection 30 seconds later.
Mounting Instructions
The OccuSwitch can be mounted in two ways: recessed in the ceiling or surface-mounted using the LRH1070 ceiling box. The ceiling box provides breakout ports for cable ducts and a central breakout piece. When selecting a location, avoid cold spots to prevent condensation.
Fixing the OccuSwitch in a Ceiling (Recessed):
- Requires a ceiling cut-out of approximately Ø 80-82 mm.
- Minimum ceiling depth required: > 50 mm.
- Maximum ceiling thickness: ≤ 30 mm.
- The diagram shows the unit being inserted into the ceiling and wires being connected.
Fixing the OccuSwitch on a Ceiling (Surface-Mounted):
- Uses the LRH1070 ceiling box.
- Screws recommended: No. 8 (Ø 4 mm).
- The diagram shows the OccuSwitch attached to the ceiling box, with dimensions indicated.
- Wiring connections (1, 2, 3) are shown.
Electrical Installation
Installation can be done using conventional wiring or Wieland connectors (requiring the LCC1070 cable). The OccuSwitch includes a detachable mains connector for easy installation, which is removed if the Wieland cable is used. The mains connection is protected by a retractable cover and secured with a tie wrap.
Installation (Conventional Wiring):
- Shows a standard connection to Line (L) and Neutral (N).
Installation (Wieland):
- Illustrates the connection using the LCC1070 Wieland cable, featuring a green connector. ✔️
Parallel Operation:
- Parallel Installation: Shows multiple units wired in parallel for expanded coverage. This method limits the total load to 6A and is typically for one mains group.
- Parallel Connection (Advanced Only - LRM1080): Utilizes a bus signal for movement detection, allowing each unit to handle up to 6A across multiple mains groups or phases. A slight delay in switch-off between units may occur. Maximum 10 LRM1080 units can be connected in parallel.
Note: The OccuSwitch connector accepts cables from 1.5 to 2.5 mm². For heavy or single-core ridged cables, using the LCC1070 Wieland cable is strongly advised to prevent the OccuSwitch from being dislodged from the ceiling due to cable weight.
Commissioning and Settings
Daylight Control
Daylight Override
To enable, turn the dial counterclockwise (↪️) away from the OFF position to set the required light level. To disable, turn clockwise (↩️) to the OFF position.
Daylight Switching
To enable, set the DIP switch to ON and set the light level (as per Daylight Override). Lights switch off if the level is above 220% for over 15 minutes. They switch on again when the light level drops below the required level.
Enabling Daylight Override and Switching:
- Shows the calibration dial with MIN/MAX settings and an OFF position.
- Depicts DIP switches labeled '1' and '2' for function selection.
Note: This function works best when the required light level matches the installed light level. The OccuSwitch may automatically adjust the switch-off level to prevent rapid cycling. A test cycle (switch off once or twice with a 15-minute delay) may occur upon reconnection to mains power.
Local Control (LRM1080)
The advanced LRM1080 version responds to Philips remote controls. The IRT8050 is recommended. It responds to channel 1 codes (on/off) and default group A/general codes. The IRT9090 remote allows changing group addresses for distinct control. Preset commands are not supported. Remote control operation requires being within the OccuSwitch's detection area.
IRT8050 Remote Control: A wall-mounted remote control unit.
Absence Mode
In absence mode, the OccuSwitch does not automatically switch lights on. A remote control must be used to turn lights on. Lights switch off 1 to 30 minutes after the area is vacated. Activate absence mode by setting the DIP switch to the appropriate position.
Enabling Absence Mode:
- Shows DIP switches labeled '1' and '2' with options for 'Auto on' and 'IR on'.
IRT9090 Remote Control Operations (LRM1080)
Set Required Light Level
Ensure sufficient ambient light is available and no daylight is present. Aim the IRT9090 at the OccuSwitch and press the "save" button. The lights will flash once to confirm the new level is stored.
Change Power-Up Behaviour
By default, the OccuSwitch turns on when connected to mains. To disable this and start movement detection 30 seconds after mains connection, select the "power up" button on the IRT9090, then "off". Aim at the OccuSwitch and press the green "send" button. Lights flash once to confirm.
Restore Defaults
To reset to factory settings, aim the IRT9090 at the OccuSwitch and press the "reset" button.
IRT9090 Remote Control Layout:
- Shows buttons for 'power up', 'IR group', 'send', 'reset', 'delay', 'daylight', 'RF channel', 'scene', etc.
- Includes a Luxmeter icon and indicates a maximum operating range of 17 meters.
- The diagram shows how to aim the remote and press the 'send' button.
Change IR Group
Both OccuSwitch and remote controls can operate in 7 groups (A-G). Ensure they are in the same group. Select "IR group" on the IRT9090, then the desired group (1-7 or A-G). Aim at the OccuSwitch and press "send". Lights flash once to confirm.
Note: The IRT9090 sends power-on and IR group settings together. To erase previous settings, press "reset" then "send".
Warnings:
- Do not use outside specified range, especially heights above 3.5 meters.
- Avoid environmental conditions outside normal office settings (temperature, humidity).
- Keep away from heat sources like electrical heaters within the detection range.
- Avoid use with devices that can be damaged by rapid on/off switching.
Warnings (Advanced Version):
- Avoid use with semi-continuous IR appliances (IRDA, phone communication, etc.) as they may send IR messages without a link. Disable these features.
- Avoid use with electronic ballasts operating near the IR transmission frequency (36Khz), especially if their light is visible to the IR receiver.
