PA4600-BB is a short range, two-beam safeguarding device. It is suited to detect the torsos of personnel entering a hazardous area. Installation and alignment is simplified with Individual Beam Indicators, which glow red when the beam is out of alignment or blocked. The separate Scan Codes allow the installer to select unique scan frequencies that eliminate cross-talk with adjacent PA4600 systems. Diagnostics are greatly enhanced with the LED status indicators and numeric displays. The active-passive design simplifies the electrical connections, as no connections are needed at the Passive (mirror) assembly.
