Battery load test
Purpose and principle
In case of mains interruption the power supply of the fire detection system relies on an internal
battery pack. The capacity of the battery pack is sufficent to keep the system for a couple of
hours operating (
page 32, Faults). As the lifetime of batteries is limited, a battery load test has
to be performed periodically to ensure a good condition of the battery pack: For 10 seconds the
battery is highly loaded and the battery voltage is monitored. If the voltage drop is beyond a cer-
tain value, the battery pack has to be replaced.
Frequency
The batterie test is automatically performed by the system every 24 hours. If the battery is dama-
ged, or provides only an insufficent capacity, a fault messages is displayed.
Once a year the battery test has to be performed manually.
