Frequently Asked Questions - 20850.B Vimar
How do I install the Vimar 20850.B motion detector?
Installation should be performed by a qualified electrician. Mount the detector at a height of 2-3 meters, connect to 230 V AC mains following the wiring diagram in the manual, and adjust settings using the potentiometers.
What is the detection range of the 20850.B?
The detection range is up to 12 meters at a mounting height of 2.5 meters, with a 180-degree detection angle. Range may vary based on mounting height and ambient temperature.
Can I use the motion detector outdoors?
Yes, the detector has an IP44 rating, making it splash-proof. However, it should not be exposed to direct rain or water jets. Mount under an eave or in a sheltered area for best durability.
How do I adjust the time and lux settings?
The detector has two adjustment potentiometers: TIME (10 seconds to 10 minutes) and LUX (3 to 2000 lux). Turn the knobs with a small screwdriver. The LUX setting determines the ambient light level at which the detector activates (set to sun symbol for day/night operation).
Why does my motion detector trigger false alarms?
False alarms can be caused by pets (reduce sensitivity or adjust mounting height), strong drafts (e.g., heaters), or moving objects like tree branches. Ensure the detector is not facing a heat source or reflective surfaces. Reduce detection range if needed.
What is the maximum load this motion detector can switch?
The maximum load is 800 W for incandescent lamps and 200 VA for fluorescent or LED lamps. Do not exceed these values to avoid damage. For inductive loads like fans, use a contactor.
How do I clean the motion detector?
Clean the lens and housing with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners as they can damage the sensor. Regular cleaning ensures optimal detection sensitivity.
Can I replace the sensor module if it fails?
Yes, the sensor module and lens cover are replaceable. Contact Vimar service centers or authorized dealers for genuine spare parts. Disconnect power before opening the unit for replacement.
Does the motion detector work in complete darkness?
Yes, because it uses passive infrared (PIR) technology which detects heat motion, not visible light. The LUX setting can be adjusted to allow operation in darkness or only in daylight.
What is the warranty period for the Vimar 20850.B?
The standard warranty is 2 years from the date of purchase, covering manufacturing defects. Proof of purchase is required. Warranty does not cover damage from improper installation or misuse.
