Programming the extinguishant board
The extinguishant board manages a gas extinguishant system activated by automatic or manual commands:
• automatic commands triggered by the fire-control panel when the programmed zones go into alarm status.
• manual commands from devices connected to the extinguishant-board inputs or set up as fire-detection loop
input points.
Therefore, the board makes use of its own terminals and those of the control panel zones, in order to
obtain the activation conditions and command the outputs:
