REEF String RS-202: Centralized Radio Surveillance Security System for Commercial and Residential Real Estate

Central Control Panel REEF Sting RS-202P connects to Base Station REEF String RS-202BS, conducts initial data analysis, decodes messages and feeds them onto the PC of the operator with the installed REEF Strizh software. In cases of power failures or software malfunctions on the central computer, REEF String-202P serves as a reserve fully functional Control Panel without losing any of the on-site transmitter signals.

Base Station REEF String RS-202BS receives via radio channel the Alarm and Service messages from Guard and Fire signals from on-site transmitters in system REEF String-202 and transmits them via protocol RS-485 further (up to 1.5 km) onto the Central Control Panel REEF String RS-202CP and to the Operator’s PC with installed REEF Strazh 202 software.

On-site Transmitter Communicator REEF String RS-202TC receives data from the on-site guard or fire detector through ContactID interface and sends it to the Central Control Panel REEF String RS-202 via a FREE NOISE-RESISTANT RADIO CHANNEL to distances of up to 70 km WITHOUT RETRANSMISSION. СIt is compatible with all detector devices supporting Ademco ContactID (Ademco, DSC, Bolid etc.). Provides communication checks between devices and the Base Station every 4 to 12 minutes.

REEF Strazh RS-202 is an independent software package for security surveillance of stationary guarded locations. With the help of this software you can create an Autopilot Monitoring Workstation (AMW) on the Operator’s PC wherever you choose it to be.

Antenna CXL 70-50C/L is used in REEF String RS-202 system as the Base Station antenna for secure radio channel transmission from on-site transmitter devices.

Aerial Ampifier RS-202AU is supplied in the Central Control Panel standard package of REEF String RS-202. RS-202AU is a receiver amplifier and is used to increase power of the signals transmitted to the Base Station RS-202BS from transmitters RS-202TP and ContactID-Communicators RS-202TC via a radio channel.

LIRA-433, on-site targeted antenna 433 МHz, +11 dBd
Is designed for greater distance range and better communication from on-site transmitters in REEF String RS-202, REEF String RS-200 and REEF String-701 systems as well as between all other transmitters and receivers operating in the 433 MHz frequency band.
Original patented design of the symmetry device contains a band filter, which well adjusts antenna to the cable only within the operating range, reduces noise level at the output and provides secure lightening protection for connected equipment.

On-site Transmitter Panel with an in-built transmitter REEF String RS-202TP communicates information on Guard Contours' status, Armed/Disarmed signals, power supply details, etc., onto the Central Control Panel of the RS-202 system via a FREE NOISE-PROOF RADIO CHANNEL within DISTANCE RANGE OF 70 KM without retransmission of the signal
