VM520 Voice Module
The VM520 is a simple voice evacuation module
which memorises and amplifies three voice
messages programmed during manufacturing.
The VM520 is designed to provide voice
evacuation in small buildings or small public
areas in large buildings.
Features
• Fully monitored system when used in
conjunction with MINERVA Analogue
Addressable Fire Controller, with all speaker
cabling faults detected, enabling use of this
unit on projects with full BS5839 requirements
• Customised messages available
• Messages can be triggered via MINERVA
address loop or via closing contact inputs
• Output capacity for up to four loudspeakers
• Clear “test” message can be transmitted for
the weekly system check, instead of
“evacuate”. This will prevent any
misunderstandings at test time.
