17.2.5 Address switch
Extinguishant modules are connected to the serial bus of the Sigma CP detection part of the control panel and
each module must be allocated an address between 1 and 7 using the binary coded DIP switch.
The switch setting are shown in this table
Internal controls on extinguishant modules
18. Internal indications
18.1 Detection part
To assist in identifying fault conditions which are not detailed on the front of the control panel, a number of
internal indicators are visible with the control panel door open as follows:
18.1.1 Mains fail
Indicates that the 230V AC supply is not present and the system is running on standby batteries.
If there is not a power cut, check the panels mains fuse.
18.1.2 Batt fail
Indicates that the standby battery has become disconnected or that the charging circuit of the control panel has
failed. Check that both batteries are connected and linked together. Test battery. Disconnect battery and ensure
that 28 Volts can be measured on battery charger leads.
18.1.3 CPU fault
Indicates that the processor has failed to correctly execute code and has been re-started by the system watchdog.
The watchdog reset switch must be pressed to clear the CPU fault condition.
Press watchdog reset. If system does not return to normal then the panel is probably damaged and needs the
circuit board replacing.
18.1.4 Aux 24V fault
The Aux 24V and R0V terminals provide a 100 milliamp, 24V DC power supply for power fire alarm ancillary
equipment. This LED indicates that fuse protecting the R0V output has operated and the rating of this output has
been exceeded. The fuse is a self resetting type and the supply will resume when the fault condition is removed.
18.1.5 Batt low
Illuminates when the system is running on batteries and the battery voltage is between 21.5 V and 20.5 V (the
minimum battery voltage).
