Control interface for VX-2000DS
The control interface DS-EC1 can disable the (AC/DC) power failure information to the TOA voice
alarm (VA) systems VM-3000, VX-2000 and SX-2000 by activating ist control input DIS so that the
VA system stays in normal mode even during battery backup. The failure information is available at
the separate control output EXT.F., so that the failure can be indicated by the function “external
failure” (VX-2000 with firmware version 2.7 and higher, VM-3000 of version 2, SX-2000 of version
3) via the failure receipt function. The module can be mounted on DIN-rails.
