Wireless alarm communicator Satel RK-1K 433.05-434.79 MHz White

The Satel RK-1K wireless alarm communicator operates in the 433.05–434.79 MHz band and is designed to provide reliable radio communication between transmitters and security control equipment. With a compact housing measuring 118 mm × 72 mm × 24 mm and a white finish, the device integrates into existing alarm and access control installations and supplies stable signal transmission for remote control and alarm reporting. It supports power supply from a 12–24 V input and includes relay outputs and I/O lines intended to interface with alarm control panels and auxiliary devices.

Advantages

The communicator offers compact dimensions and a discreet appearance that simplify installation in residential and commercial environments. Radio operation in the specified 433 MHz range ensures compatibility with compatible keyfobs and transmitters, while the combination of relay output and dedicated inputs/outputs enables both control of electrical loads and integration with alarm panels. The device is built for straightforward wiring and dependable operation under standard control-system voltages.

How to use

Install the communicator in a sheltered location close to the devices or control panel to be operated. Connect the power supply within the 12–24 V range and wire the relay output and I/O lines to the corresponding terminals of the alarm control panel or to the load to be controlled. Pair compatible keyfobs or transmitters according to the manufacturer's pairing procedure so that remote commands activate the relay or trigger inputs. After installation, verify radio range and correct operation of all functions, and make any required adjustments to placement or antenna orientation to ensure consistent communication.

Usage recommendations

Place the communicator away from large metal enclosures and sources of strong radio interference to maintain optimal signal strength. Use appropriate surge protection and follow local electrical safety standards when connecting to power and load circuits. Regularly test paired transmitters and the relay function as part of routine maintenance of the security system.
