21. Maintenance
SIGMA XT control panels do not require any specific maintenance but should the control panel
become dirty it can be wiped over with a barely damp cloth. Detergents or solvents should not be
used to clean the panel and care must be taken that water does not enter the enclosure.
The control panel contains sealed lead acid batteries to provide standby power in the event of
mains failure.
These batteries have a life expectancy of around 4 years. It is recommended that these batteries
be tested in accordance with the battery manufacturer’s recommendations annually to determine
their suitability for continued standby applications.
Testing of the extinguishant system should only be carried out by trained personnel and must be
done with appropriate isolation measures in place to ensure that accidental discharge of the
extinguishant agent is avoided.
Should the control panel become faulty the complete electronic assembly and front plate can be
replaced.
To do this, any configured options should be noted then both mains and battery power should be
removed before the work is started.
The field wiring should be carefully labelled and removed from the terminals. The power terminal
block can be unplugged from the PCB by pulling it towards you.
The PCB can now be taken out of the panel by removing the 2 screws.
Fitting the new PCB is the reverse of the procedure for removing the board.
22. Record of configuration
Use the table below to record the configuration codes that have been set on the control panel for
future reference. Place a tick in the box for any configuration options that are set.
It is recommended that a copy of this table is left with the control panel under the supervision of
the person responsible for the fire protection system.
NOTE: Setting the options marked with asterisks does not comply with EN54-2
