5. Standard requirements for battery
If the power supply is to be used in an alarm system which is to meet requirements of the
EN 50131 standard for Grade 2, the battery should provide 12 hours of system operation in
the event of mains power loss. Table 2 contains information on what current must be used for
charging batteries of different capacities so as to meet the requirements of EN 50131 for
Grade 2.

6. Battery testing by the power supply
After starting the power supply, provided that the battery testing mode is enabled and
a sufficiently charged battery is connected, the
LED should go on after about 10
seconds. The battery is checked every 4 minutes for ten to twenty seconds. Duration of a full
test of the battery charge status is up to 12 minutes. If the battery voltage drops below
11.5 V, the power supply will report a trouble on the WB output, and the
LED will start
blinking (optionally, the trouble may be audibly signaled). When the voltage goes down to
10.5 V, the power supply will disconnect the battery to protect it against full discharge and
damage. The
LED will go off.
