Frequently Asked Questions - IR28B+ Elektrobock

How do I adjust the time delay on the IR28B+?

Locate the time adjustment knob on the detector. Turn it clockwise to increase the delay (up to 10 minutes) or counterclockwise to decrease (as low as 10 seconds). Test the setting after adjustment.

What is the detection range of the IR28B+?

The detection range is up to 12 meters in a 180° field of view. Optimal performance is achieved when the detector is mounted at a height of 2-3 meters.

Can the IR28B+ be used outdoors?

Yes, the detector has an IP44 rating, making it splash-proof and suitable for outdoor use under eaves or covered areas. Avoid direct exposure to rain.

How do I connect the IR28B+ to my electrical system?

Connect the wires as follows: L (brown) to live, N (blue) to neutral, and Load (black) to the light or device you want to control. Ensure power is off before wiring.

Why does my IR28B+ not detect movement?

Check that the detector is receiving power, the light threshold is set to 'night' if using in daylight, the time delay is not set to minimum, and there are no obstructions in the detection zone.

Does the IR28B+ have a dusk-to-dawn function?

Yes, the adjustable light threshold allows the detector to operate only in low light or darkness. Turn the LUX knob to set the desired ambient light level.

Is the IR28B+ compatible with LED bulbs?

Yes, the detector can control LED bulbs. However, ensure the total load does not exceed the maximum rating (typically 1000W for incandescent, lower for LEDs). Use a suitable relay if needed.

How do I clean and maintain the IR28B+?

Wipe the sensor lens and housing with a soft, dry cloth. Do not use abrasive cleaners or solvents. Regular cleaning ensures accurate detection.

What does 'L' and 'N' mean on the wiring diagram?

'L' stands for Live (phase) and 'N' stands for Neutral. These are standard designations for AC power connections. The 'Load' terminal connects to the controlled device.

How do I reset the IR28B+ to factory settings?

There is no dedicated reset button. To reset, turn off power for a few seconds, then turn it back on. The detector will restart with the current physical knob settings.
