The wireless OKS-820 doorbell set includes the battery-operated OKE-820 doorbell receiver and the OHJ-721 doorbell control button. The connection works with radio frequency, the range is approx. 30 m without obstacles.
The OKE-820 receiver is placed free standing on a flat surface or it can be attached to the wall with the included bracket and screws.

The clever bayonet attachment makes changing batteries easy. OKE-820 operates on two AA stick batteries for a long time and can indicate when they need to be replaced with an indicator light. High reception sensitivity ensures operation even in more challenging installation locations. There are six (6) different beeps. OKE-820 is equipped with an indicator light that visually signals the ringing of the doorbell.
The volume control also enables muting, so that only the indicator light remains on.

The stylish OHJ-721 doorbell button has an IP55 protection rating and is also equipped with a low battery detection function. The battery is already installed in the controller, and the package also includes mounting accessories. The battery life is long and its replacement is easy.

OHJ-721 works well even in cold conditions. OKE-820 is compatible with all current WIRELESS controllers. The same receiver can be controlled from a maximum of 32 different controllers, and different controllers can be assigned their own signal tone if desired. So you can put several doorbell buttons on the doorbell. One button can also be conveniently linked to several doorbell receivers.

TIP: For example, a WIRELESS LTO-609 motion detector can be used as a controller, in which case the doorbell conveniently functions as a motion alarm.
