Baldwin Boxall - Voice Alarm Monitoring Options

Our voice alarm monitoring products are BS EN54 certified and can be used with both VIGIL3 and VIGIL2 systems.

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.
