remote control of security networks
PZK BRNO has become a leading partner in the supply of components and integrated solutions for distributed antenna systems (DAS) of mobile operators as well as integrated systems of emergency services. Emergency radio communication systems, also known as public safety,„ “ are now part of every modern building and are also implemented when renovating existing buildings.
areas of use
safety first
Authorities such as the „National Fire Protection Association“ recommend that all passive networks of emergency services systems be equipped with a remote monitoring system that would detect faults in the passive network of high-frequency coaxial cables, taps, antennas that are integrated in a building without the ability of quick access to them. Typically, only active elements are monitored today. Without real-time monitoring of the DAS system, the building may not be prepared for emergency radio traffic. The likelihood of damage to the DAS system during the completion of the work is high. This is due to various improvements, additional plumbing work, installation of CCTV, and maintenance. Something as simple as disconnecting the antenna and forgetting to reconnect it will compromise the integrity of the entire DAS system.
DAS smart monitoring
A smart passive system enables real-time monitoring of the entire DAS system, i.e., the performance of structured cabling, radio frequency components, and antennas. The smart system consists of a Smart gateway and Smart couplers, which replace conventional passive couplers. The real-time monitoring capability ensures that DAS integrators, building owners, emergency responders can rely 100% on the functionality of the critical safety network.
how the smart system for DAS works
The radio frequency signal of the emergency services is connected to a Smart gateway. It feeds DC voltage into the entire system via coaxial cables to power the Smart couplers. This eliminates the need to install any additional power supply. The smart coupler is designed for the frequencies of 130-960, 380-512, or 750-960 MHz. Smart couplers measure the voltage standing wave ratio (VSWR) on each port, with a calibrated signal sent from the Smart gateway. By storing and comparing the VSWR on each port, the system continuously monitors changes and proactively indicates faults such as interruptions or short circuits. The Smart gateway then sends a fault signal via email, SMS, SNPM…
