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.

VIGIL2 monitoring products available:
 

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
   

BEL1 - END OF LINE:

• An active unit which is installed on each loudspeaker circuit

BEL1IP - END OF LINE:
