Wireless waterproof push button range 150m, Bulik PDH-991 12V, white SUN10000015

Wireless doorbell button – reliability and ease of use

The hermetic wireless button Bulik PDH-991 is an ideal solution for those who value convenience and reliability. Designed to work with Bulik wireless doorbells and other devices from the X series, it provides comfortable use and easy installation. Its hermetic housing protects against the effects of weather conditions, making it an excellent choice for both home use and in places exposed to moisture.

Functionality and range

The button offers a range of up to 150 meters in open area when working with Bulik doorbells. It is worth remembering that obstacles such as walls or metal structures can affect the operating range – wood and plaster can reduce it by 5-20%, brick by 20-40%, and reinforced concrete by as much as 40-80%. In the case of metal obstacles, it is recommended to avoid using radio systems due to the significant limitation of range. Additionally, it is worth paying attention to the potential impact of power lines and GSM transmitters located nearby. The button is powered by MN21 or MN23A battery, which ensures long-lasting operation without the need for frequent replacement. It also has an acoustic signal confirming activation.

Installation and application

The button is extremely easy to install and does not require specialized tools. It can be easily surface-mounted anywhere outside the building, e.g. at the gate or entrance door. Thanks to the IP44 protection class, it is resistant to splashing and weather conditions. The button is perfect for single-family homes, companies, and places requiring a reliable notification system. The ability to work with a repeater further increases its functionality and operating range. This is especially useful in larger facilities or in places with difficult signal reception.
