10.5 Power supply module
The power supply module is installed on the basic circuit board of the FACP 8000C. This module
accommodates the entire voltage supply for the fire alarm control panel and the +12 V DC supply
voltage for external devices.
Maximum current load from external users will depend on control panel configuration and accounts
for approx. 2A. One power supply module may be installed in each FACP 8000C. If necessary,
additional supply is possible from a monitored external power supply unit.
