Reef Ring-2 system is a low-cost solution for implementing radio channel security alarm at medium-sized facilities.

Reef Ring-2 system provides real operating range in line of sight up to 800 meters. Operating range inside buildings depends on the material of walls and ceilings. Basing on hardware of Reef Ring-2, you can create inexpensive system of local address radio security with capacity of up to 100 facilities, including both portable radio buttons and stationary transmitters.
Panic radio buttons and stationary transmitters of the system are designed for wireless transmission of alarm signals in case of attacking protected persons, triggering security alarm and intrusion into facilities.


  • System operates at open frequency of 433.92 MHz ±0,2%, power of transmitters at facility is 10 mW
  • Permit to use radio frequency is not required for operation of the system
  • Amplitude modulation
  • Real communication range in the line of sight is 200-800 m
  • 16-bit encoding
  • Wide operating temperature range


Receiving equipment:

  • RR-2R – radio receiver with one output relay;
  • RR-2R5 – radio receiver with one output relay and option of indicating up to five numbers of transmitters;
  • RR-2P – indicator panel-programmer to prepare the system for operation and displaying the number of activated transmitter.

Transmitting equipment:

  • RR-2T – personal hand-held transmitter (panic button);
  • RR-2TS – stationary transmitter of alarm messages with two alarm loop circuits: input/output delay and without delay.

Main areas of activity of Altonika include development and manufacture of automotive and industrial electronics, radio channel security systems, medical equipment and radio communications.
