niko 25458 Presence or Absence Detector
Product description
- The device detects the movements and the presence of persons using a passive infrared sensor (PIR). It reacts most sensitively to movements which are tangential to the monitored area (1a).
- Movements directly towards the detector have a reduced sensitivity of approx. -50% (1b).
- The switching duration is extended as long as movements (entire area 1d) or the presence of persons (presence area 1e) are detected.
- The detector is used to increase the detection range of a Master detector.
Application
The detector is suitable for indoor use for lighting control. Outdoor applications require the use of an IP55 housing (accessory). Adhere to the following instructions during installation:
- Install only on stable ceilings.
- Mask moving objects in the monitored area by covering the lens.
- Do not place any lamps below or less than 1 m next to the detector (2a).
- Do not install in direct cold (2b) or hot air flows (2c).
Safety notes
Ensure that the electrical lines are de-energized before installation. Installation is only permitted by electricians in compliance with local legislation.
Installation
| H | max. Ø 16 m |
|---|---|
| 2,5 m | 12 m |
| 3,0 m | 14 m |
| 3,5 m | 16 m |
| 4,0 m | 16 m |
| 5,0 m | 16 m |
| 6,0 m | 16 m |
The detector is intended for ceiling installation at a height of 2 to 6 m. The diameter Ø of the monitored area depends on the installed height (1c). Install the detector as follows:
- Remove the front cover.
- Wire the detector according to item 5.
- Fasten the detector in the flush-mounting box.
- Configure device according to item 7.
- Mount the front cover.
Wiring
The electric circuit must be protected with a circuit breaker.
| Current conduction line | L |
|---|---|
| Neutral conductor | N |
| Secondary detector | S |
A maximum of 10 secondary detectors can be connected to the S terminal. Keep wires short (max. 100 m).
Connection of loads
The secondary detector can be used only in combination with a Master detector.
The load is switched via the Master detector.
Configuration
The detector is ready for operation approximately 1 minute after connection to
the electricity mains. Parameter changes must be made during operation: Range:
SENS is used to set the range of the PIR sensor (4a).
Display
The following statuses are indicated by the LED.
| Status | LED indication | Duration |
|---|---|---|
| Start-up | approx. 1 min, short flashes | |
| Movement detection |
The secondary detector only issues a 1 second pulse every 5 seconds when set to permanent detection. The LED only shows a permanent movement every 5 seconds.
Troubleshooting
The 16 m presence detectors are compatible with the 30 m lens (accessory). If the range is insufficient, the lens can be replaced.
The switching output does not switch:
- Check the lamp / fuse protection
- Check the Master
The switching output switches too frequently:
- Reduce the range
- Cover the lens
