Niko 350-20078: 360° Presence and Absence Detector
Model: 350-20078
1. Description
The Niko 350-20078 is a 360° presence or absence detector designed for surface mounting. It features an integral unit with single-channel on-off control, a passive infrared (PIR) motion sensor, a light sensor, and an integrated IR receiver. External units like push buttons and lighting fixtures connect directly to the ceiling-mounted detector.
This detector can operate as a standalone unit or as a master unit in combination with one or more secondary detectors (model 350-20079). It can be installed and operated using factory settings, but for optimal lighting control, it is recommended to adjust these settings based on environmental conditions and specific lighting requirements. Adjustments can be made directly on the device using integrated potentiometers and DIP switches, or via an optional IR remote control (model 350-20089).
2. Installation
2.1. Connection
Danger: Ensure power is disconnected before installing the detector. Connect the device to the mains voltage only after complete installation.
- A. Stand-alone: Refer to the wiring diagram (fig. 1A).
- B. In combination with one or more secondary detectors: Refer to the wiring diagram (fig. 1B).
2.2. Mounting
- Tip: Avoid installing the detector near heat sources (stoves, electric heaters), air currents (ventilation systems), or moving objects (fig. 2), as these can cause unwanted activation due to motion and heat detection.
- Tip: The recommended mounting height is between 2 and 3.4 meters. Optimal performance is achieved at a height of 3 meters, providing a detection range with a 24-meter diameter on the ground and 17.5 meters at an 80 cm height (e.g., table height) (fig. 3).
- The detector is suitable for direct mounting onto the ceiling (fig. 4).
3. Settings
3.1. Factory Settings
The detector's parameters are factory-set as follows:
| Parameter | Factory Setting |
|---|---|
| Application (Presence/Absence Detector) | DIP switch 1: Automatic on/off |
| Push button functions | DIP switch 3: Short press allows light on and off (eco off). Long press for 2-hour override. |
| Daylight dependency | DIP switch 4: Short press is daylight-dependent. Long press is always daylight-independent. |
| Sensitivity of motion sensor | High |
| Light sensitivity | 200 lux |
| Switch-off delay | 10 minutes |
3.2. DIP Switches
Figure 5 illustrates DIP switch settings for application and motion sensor sensitivity.
Application Setting
| DIP switch 1 | Application | Function |
|---|---|---|
| ON | Presence detector (automatic on/off) | Detector automatically switches on lighting based on preset lux value and motion detection. |
| OFF | Absence detector (manual on/automatic off) | Detector switches on lighting only when push button is pressed, based on lux value. Lighting remains on for the set delay after last motion detected, then switches off. |
Push Button Functions
- ON: Light can only be switched on with a brief press. 'Eco off' and 'long push' functions are deactivated.
- OFF: A brief press allows immediate switching on/off without waiting for the switch-off delay (= 'eco off'). Pressing the button for over one second activates a 2-hour override for lighting and delay settings.
Daylight Dependency
- ON: Brief press is daylight-independent.
- OFF: Brief press is daylight-dependent. Long push is always daylight-independent.
Note: The 'eco off' function is the most energy-efficient way to switch on lighting, allowing manual control to avoid waiting for the switch-off delay.
Sensitivity Setting
The two rightmost DIP switches adjust motion sensor sensitivity (Minimum, Low, High, Maximum). Refer to Figure 5 for specific switch positions.
3.3. Potentiometers
Located under the detector housing, two potentiometers allow adjustment of light sensitivity and switch-off delay (fig. 6).
| Potentiometer | Function |
|---|---|
| Light Sensitivity | Sets the light level (lux) at which lighting should switch on. Ten fixed levels: 20, 50, 100, 200, 300, 400, 500, 700, 1000 lux, and ∞ (daylight-independent). |
| Switch-off Delay | Sets the switch-off delay. Eight preset values: Pulse, 2 min, 5 min, 10 min, 15 min, 30 min, 60 min. |
Confirmation of settings: The green indication LED flashes once, and the red indication LED flashes multiple times according to the selected setting. Tables detail the number of red LED flashes for each setting.
Example: Setting light sensitivity from 300 lux to 400 lux results in one green flash and six red flashes.
Example: Adjusting switch-off delay from 10 minutes to 15 minutes results in one green flash and five red flashes.
4. IR Remote Control
The IR remote control (fig. 7) offers an alternative to manual adjustments for selecting applications, performing tests, and entering parameters.
4.1. Function Buttons
- Light 1 On/Off: Permanently switches lighting on or off, irrespective of detected motion or light level. Activation steps provided.
- LED On/Off: Switches the indication LED on or off. The LED flashes when 'push' or 'On/Off' is activated.
- Status Ch 1: Displays current channel 1 settings via LEDs (green flash, then red for lux, then red for delay). Example provided.
4.2. Set Buttons
To change detector settings:
- Press 'unlock' three times within five seconds to unlock the device (green LED flashes twice). The device enters 'set' mode.
- Adjust light level or switch-off delay using the provided buttons.
- Press 'unlock' once to lock the device again (green LED flashes twice). Modified settings are activated.
Note: If not manually locked, the device locks automatically after two minutes, saving all changes.
| Button | Function |
|---|---|
| Ch 1 (Red buttons) | Set desired light level (lux). Ten fixed values: 20, 50, 100, 200, 300, 400, 500, 700, 1000 lux, and 'No lux' (daylight-independent). |
| Learn actual lux | Sets current room light level as the desired switch-on point. Red LED flashes once to confirm saving. Minimum (20 lux) or maximum (1000 lux) is saved if outside the range. |
| Ch 1 (Blue buttons) | Set desired switch-off delay. Six fixed values: 2, 5, 10, 15, 30, 60 minutes. |
| 8 Hours | Permanently switches lighting on for eight hours. Red LED flashes upon confirmation. Press again to deactivate. Cannot be deactivated via push button. |
| Fact. setting | Resets the device to factory settings. |
| Test | Activates walking test. Blue LED lights up. Red LED flashes with detected activity. Lighting on for 5 seconds. Light sensor inactive during test. |
5. Operation and Use
5.1. Activation
Power the detector only after all cables are connected. It is ready for use approximately 120 seconds (warm-up time) after power-on. The red indication LED flashes during warm-up; the green LED flashes twice when ready.
5.2. General Operation
The integrated light sensor continuously measures ambient daylight and compares it to the set lux value. The light automatically switches on only when motion is detected AND there is insufficient daylight.
- Lighting remains on as long as motion is detected and daylight is insufficient.
- After the last motion is detected, lighting stays on for the preset switch-off delay (1-60 minutes) before switching off.
- Lighting also switches off automatically if the daylight level becomes sufficient, even if motion is still detected.
5.3. Detection Range
The detection area can be extended by connecting up to ten secondary detectors (350-20079) to one master (350-20078). Both master and secondary detectors share the same detection range (24m diameter circle). For full coverage, a 30% overlap is recommended (fig. 8). A supplied cover cap can reduce the detection range or angle if needed.
5.4. Examples of Applications
- Classroom: Presence detector mode. Automatic on/off based on motion and light. Manual on/off via push button. Long press function for extended periods.
- Office: Absence detector mode. Manual on via push button (daylight-independent). Automatic off after delay. 'Eco off' and 'long push' deactivated.
- Staircase: Presence detector mode. Automatic on/off based on motion and light. Manual on via push button, independent of daylight.
6. Maintenance
Keep the detector lens clean and dry to ensure proper function. Use a damp cloth with mild detergent. Avoid applying pressure to the lens. Contact an authorized installer for defective parts.
