The VMMS is a distinctive and bespoke solution for providing clear and concise audible warning messages or status information to drivers and passengers alike. Each unit can broadcast specific audio clips through two separate speaker outputs – these are independent of each other to allow driver/passenger audio separation.

Fire Suppression Integration

As part of the FVS Fire Suppression System, the VMMS acts as the control hub for each of the monitoring devices. The unit includes a specific feature to monitor the status of the system pressure, engine bay temperature and saloon smoke detector. In addition the unit has a safety shutdown function in line with TFL requirements.

Bespoke Audio Options

The VMMS includes a number of input connections, which each activate the broadcasting of pre-programmed audio clips. An extensive range of spoken messages are already available, but custom messages or sounds can be requested. This flexibility allows the VMMS to be used as either a warning system for driver alerts, or to provide informative feedback to passengers such as with a ‘Bus Stopping’ announcement. The VMMS could also be used to replace multiple buzzer and bell combinations with a single unit. The sound recordings are factory programmed. Any customer specified recording or sound is embedded into the unit. The unit library can contain a maximum of 256 recordings. A single CAN message or hard wired input can trigger the playback of any message in the library.
