RM-1 Remote Microphone Interface

providing the DAA2 with remote paging and/or message override capabilities. The RM-1 may be
used for paging locally or to Noti-Fire-Net.

The RM-1 requires VeriFire Tools programming for DAA2 applications. See the DAA2
programming section of the DVC Digital Voice Command manual for programming instructions.
See the RM-1 document for further applications.
