Power supply
The mainframe does not have its own mains power supply. It is powered by either one or
two 24 Vd.c. supplies, depending on the specification of the system, connected via the
CPU card.
The d.c. power should be derived from a regulated power supply with integral battery
charger connected to standby batteries. Overall battery size should be calculated as speci-
fied in the relevant installation standards. See separate product sections for current con-
sumption.
Serial port - RS232C
The serial port, which is located on the CPU card, has two functions.
• It is used to allow downloading of system configuration files created in Integrity Editor
software.
• In an operational system it can be connected to a PC to provide status and fault informa-
tion to a terminal program such as HyperTerminal, from which the data may be printed.
