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

The Satel RK-1K wireless alarm communicator operates on the 433.05–434.79 MHz band and provides compact, battery-powered-compatible control for auxiliary devices and alarm systems. Housed in a white enclosure with dimensions of 118 mm × 72 mm × 24 mm and requiring a 12–24 V input, the RK-1K accepts signals from keyfobs to switch a relay output and also offers dedicated inputs and outputs to interface with an alarm control panel. Typical applications include remote activation of parking barriers, gates, roller shutters, blinds and other electrically driven devices, as well as remote arming and control of alarm system functions.

Advantages

The RK-1K combines compact dimensions with a focused wireless reception range in the 433 MHz band, enabling discreet installation near controlled equipment. Its relay output supports direct control of external devices, while the additional inputs and outputs provide integration with alarm panels for coordinated operation. The device accepts keyfob commands, which simplifies user interaction and reduces the need for fixed control points. Requiring 12–24 V input makes it compatible with common security and low-voltage power supplies.

Suitable for

• Remote control of parking barriers and gate drives
• Operation of roller shutters, blinds and garage doors
• Integration with alarm control panels for arming/disarming and auxiliary outputs
• Control of lighting circuits or low-voltage actuators

How to use

Mount the RK-1K in a location with adequate wireless reception and connect the device to a 12–24 V DC power source. Wire the relay output to the controlled device following the manufacturer’s wiring conventions and connect any alarm panel inputs/outputs as required for remote arming or status signalling. Program keyfobs to the communicator according to SATEL instructions to assign control rights and actions. Verify operation by sending commands from a paired keyfob and observing the relay or connected device response.

Usage recommendations

Install the communicator indoors or in a sheltered location to maintain reliable radio performance; avoid placing it adjacent to large metal structures or sources of RF interference. Use appropriate wiring practices and ensure the power supply is stable within the 12–24 V range. Follow local regulations for radio devices and consult SATEL technical documentation for advanced configuration and secure keyfob pairing.
