The MVF16 is a Multi Voice File interface, designed to be used in combination with the InterM PV-632 Multi Voice File Player.
This combination makes it possible to play voice messages, warning signals or other signals when a signal is applied to one of the MVF16’s input contacts.
The standard configuration provides one fire alarm contact, 13 regular contacts to select the according message file and two open collector outputs which can be used to switch a relay.
