Advanced QuickZone QZXL-R12 repeater panels have the same, easy to use, controls and indications as the main control panel, but mounted in a smaller cabinet. The repeaters are fully functional with ‘Silence’, ‘Resound’ and ‘Reset’ controls, as well as Disable and Test Mode functions. It is also possible to disable the controls for each or all repeater panels to make them passive (indication only). QuickZone XL panels can support up to 8 repeater panels. Repeater panels are designed to be wired in a fault tolerant (fail safe) loop configuration, to and back to the main panel again. This enables repeater panels to still work if there is a break in the cables. If replacing an older system where the existing cabling cannot be configured in a loop as above, it is possible to re-programme the panel back with a radial circuit, communications monitoring. The main circuit board has 2 switch negative inputs which can be used to sound or pulse the alarms. These inputs can also be reprogrammed for use as PSU fault inputs. The internal communications PCB has 6 switch negative programmable outputs.
