Monitoring

Baldwin Boxall – Voice Alarm Monitoring Options

VIGIL2 voice alarm monitoring products are LPCB BS EN 54 – 16:2008 certified

All critical signal paths of a voice alarm/VACIE system must be fully monitored – from the fire officer’s microphone, through the amplifiers to the end of the loudspeaker lines. Also, any faults detected with the power supply, internal battery charger and backup batteries must be reported and acted upon.

BVRDADIM/DIS – DC LINE MONITOR ISOLATOR:

  • CANBUS modules consisting of two components: BVRDADIM and BVRDADIS.
  • The BVRDADIM master unit connects to the BVRD2M router (capable of controlling up to five BVRDADIS units)
  • Enables dual loudspeaker circuits to connect to a single amplifier
  • Each BVRDADIS provides both A&B circuits for two amplifiers
  • Up to 10 spurs per loudspeaker line
  • DC line monitoring

BVRDADC – DC LINE MONITOR:

  • DIN rail mounted CANBUS module with screw terminals for connections to amplifiers and loudspeaker lines
  • 11 x amplifier surveillance (10 with automatic amplifier changeover)
  • Monitors the integrity of loudspeaker lines by measuring a small DC current

BVLAM – IMPEDANCE MONITOR:

  • Rack mountable unit
  • Enables eight loudspeaker zone selection from one amplifier
  • Provides constant impedance monitoring on each of the eight loudspeaker circuits selected

BEL1 – END OF LINE:

  • An active unit which is installed on each loudspeaker circuit

BEL1IP – END OF LINE:

  • An IP65 rated version of the BEL1.

BEL10 – END OF LINE:

  • DIN rail mounted, the BEL10 is the equivalent of ten BEL1 units
  • Typically, the BEL10 is used to ease the upgrading of an existing voice evacuation system, where loudspeaker lines are wired in a loop back to the rack

BVRDACO – AMPLIFIER/LINE MONITOR:

  • DIN rail mounted CANBUS module
  • 10 x BEL1 line surveillance with earth leakage fault detection
  • 11 x amplifier surveillance (10 with automatic amplifier changeover)
