Digital Voice Module with Record and Playback (DX-200)
The digital voice module (DX-200) controls the message playback in the SAFEPATH system. When a dry contact closure or a serial
port command initiates a file playing, the DX-200 signals the SADC to switch from the standby condition to an alarm condition for the
zone indicated. The DX-200 also has the capability of creating record or string files.
The DX-200 can store up to 999 message files. Message files may be any combination of record or string files. Up to 16 minutes of
messages may be stored in the DX-200’s PSRAM message memory. The DX-200 has a NICAD battery to power the PSRAM
message memory I.C.’s during periods of loss input power to the DX-200.
Messages can be selected to play using a dry contact closure or a command on the serial port. Dry contacts may be connected
directly to the DX-200 or to a DV-EM connected to the DX-200, but not both. Up to eight files may be selected using the dry contact
inputs on the DX-200, up to 256 files may be selected using the dry contact inputs on up to eight optional DV-EM’s; or up to 999 files
may be selected using commands on the serial port.
There are two fuses on the printed circuit board, F1 and F2. F1 is the fuse for output channel 1. F2 is the main fuse for the entire
board. See Figure 38 for fuse locations.
