26.1 Power supply values of FACP 8000C / M
The diagnostic display enables, e.g. a fast check of the power supply values of this fire alarm
control panel for service and maintenance work. In the control panel display, a diagnostic field with
individual measured values (analog measurement channels) which are automatically determined
by the control panel is displayed.
