In Australian 4100ES FIPs, only one power supply variant (SPS) is currently available,
and it has hardware and software that are specific to Australia. This unit is used as the
main power supply, but additional units may also be fitted directly to a card bay as an
expansion supply.
The system power supply (SPS) is mains powered and has backup batteries that get
switched in on mains failure. It is the initial power source for the CPU and the host
cabinet. The SPS provides 24V card power to the CPU motherboard and the other cards.
It also supplies 24V power on a separate bus to the outputs, e.g. Notification Appliance
Circuits (NACs).
The SPS also has three on-board NACs that support reverse polarity supervision. {xe
"system power supply (SPS): about"}{xe "4100U: system power supply (SPS)"}It
provides an IDNet channel, auxiliary power, an auxiliary relay, and it mounts and drives
the Alarm Relay Card.
The SPS performs functions such as brownout detect, battery transfer, battery recharge,
earth fault detection, and power limiting of outputs. It provides voltage and current
information to the CPU card, which can then be displayed on the user interface.
