Langaton ovikello REV 0082600103 harmaa valkoinen

The REV 0082600103 Grey White doorbell chime is a compact wireless chime designed for simple, tool-free installation in residential environments. The unit combines a grey and white plastic housing with battery operation and communicates with compatible transmitters at 433 MHz. With a maximum theoretical range of up to 150 meters in open space, the chime delivers audible notifications without permanent wiring, making it suitable for retrofit or temporary setups.

Advantages

The chime's wireless operation eliminates the need for electrical wiring and simplifies placement anywhere within range. Lightweight plastic construction provides resistance to routine indoor wear while keeping the unit unobtrusive on interior walls. Battery power reduces installation time and allows relocation without rewiring. Operation at 433 MHz ensures compatibility with many common wireless transmitters that use the same frequency band.

Suitable for

• Apartment entrance halls and interior doors
• Detached houses and garages where wiring is impractical
• Temporary installations such as events or short-term rental properties
• Areas needing an additional audible alert in different rooms

Key specifications

• Wireless frequency: 433 MHz
• Maximum range (open space): up to 150 meters
• Material: durable plastic housing
• Power supply: battery-operated (batteries not specified)
• Color: grey and white finish

How to use

Install the chime by inserting batteries according to the polarity markings and mounting it on a wall or other flat surface using the supplied adhesive or screws where available. Pair the chime with a compatible 433 MHz transmitter following the transmitter's pairing procedure; once paired, pressing the transmitter push button will trigger the chime. Position the unit within its effective range from the transmitter and avoid placing it inside metal cabinets or behind large obstacles that may attenuate the radio signal.

Recommendations

For reliable operation, choose fresh batteries and check them periodically. Place the chime at ear level in the primary listening area and keep at least one metre clearance from large metallic objects or dense concrete walls. Test the range from the intended transmitter location before final mounting and replace batteries when sound output becomes weak or intermittent.
