Baldwin Boxall VIGIL2 End-of-line Monitor Unit BEL1

All critical signal paths of a voice alarm 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. A VIGIL2 system has various monitoring options.

BEL1 is an active unit which is installed on each loudspeaker circuit. Up to four BEL1 units can be placed on one speaker run. All internal DIL switches must be set correctly.

Key Features:

• Monitors the critical signal path of speaker lines for open, short circuit and earth faults.
• Fault warnings are displayed on the voice alarm rack.
• Each BEL1 unit uses approximately three Watts of power, this needs to be noted when designing a system.
