    Since data wiring may have critical connections, for instance due to cable type and length, RCF FLEXCOM bus can adapt the data communication speed to the wiring characteristics and available data band. Only a few devices are necessary to design the simplest and the most complex projects, centralized or distributed: no matter if a supermarket or a theatre, an airport or a shopping centre, a fast-food or an underground, a school or a hospital.

  • Page 52: Guidance On The Measurement

    www.acornfiresecurity.com GUIDANCE ON THE MEASUREMENT OF THE SPEAKER LINE IMPEDANCE In the DXT 9000 system, monitoring of the integrity of speaker lines is made through impedance measurement at subsonic frequency (20 Hz). This method was chosen because of its good stability and accuracy of calculated values, which avoids false line fault reports that often occur with impedance measurements faster at supersonic frequencies, but more prone to interferences and errors.
  • Page 53 www.acornfiresecurity.com Amplifiers are protected and designed to operate at their maximum rated power. The best impedance range (Zmon), in which its measurement is more stable, immune to errors and repeatable, is from 50% to 100% of the load corresponding to the maximum power of the channel. With 100 V lines: 1 x 500 W →...
  • Page 54 www.acornfiresecurity.com The following formula is basically the calculation of the impedances in parallel: Zmaxend Ztot Znoend = Zmaxend – Ztot NOTE: 20 h The liNe iMpedaNce here iS cONSidered aT The frequeNcY Of which iS NOT equal TO The ONe MeaSured bY aN iMpedaNce MeTer aT The percentage difference between the two impedances is 7.14%, so it is necessary to set the tolerance to the 5% option.
  • Page 55 www.acornfiresecurity.com The total impedance (Ztot) resulting from the parallel between the load impedance already present in the line (Zline) and EOL (Zeol = 200 Ω) is easily obtainable by the following formula: Zline Zeol Ztot = Zline – Zeol NOTE: (Zline) 20 h The liNe iMpedaNce...
