To further enhance the versatility of the Syncro and Taktis fire alarm system, additional sounder output capability can be added using Sounder Boards.

These boards have 6 monitored sounder outputs, each of which can be individually programmed.

In addition to the sounder outputs each board has two general purpose, opto-isolated inputs and two volt-free changeover contact outputs.

Up to 32 of these boards can be connected to the dedicated RS485 communications bus in the control panel giving the capability of 192 additional sounder outputs with 64 general purpose inputs and 64 general purpose outputs.

The sounder boards may be mixed on the RS485 bus with 16 channel I/O boards, 8 way relay boards or 4 way conventional detection zone boards to provide a very flexible system of I/O to satisfy any requirement.

Main features

  • 6 individually fused and monitored sounder outputs
  • Fault and operated indications
  • 2 opto-isolated general purpose inputs
  • 2 volt free contact general purpose outputs
  • Remote connection to panel via RS485 serial bus
  • Common footprint to other Syncro I/O board types
  • All outputs and inputs programmable for cause and effects
  • Can be used with other Syncro I/O modules on the same panel
