30.7 Check the power supply
Check the current consumption
1. Measure the current consumption during 'Emergency power operation' and for
alarms with the highest alarm level (local alarm and global alarm).
2. Compare the measurement values with the calculation value for emergency
current capacity.
Checking the batteries
1. Measure the battery voltage (23 V min., max. asymmetry 1 V).
2. Measure the charging current.
3. Check the battery load capacity. The load test should only be performed if the
battery charge current is below 50 mA.
4. Disconnect the batteries from the charger. Do not subject the connections to
strain unnecessarily.
5. Connect the battery tester to both batteries (load resistance 5 Ω).
6. Test duration for battery 7 Ah: 20 minutes.
7. Test duration for battery 12 Ah: 30 minutes.
8. Measure the battery voltage (when the tester is connected). During the test the
battery voltage should not drop below 11 V per battery and not below 23 V for
both batteries. Always replace both batteries!
Checking for power supply faults
1. Disconnect the mains supply cable.
The following message is displayed: 'Mains failure'.
2. Disconnect the battery supply cable.
The following message is displayed: 'Supply failure'.
Checking the mains supply cable
1. Check whether the site mains supply cable is correctly fuse-protected and
labeled (fire detection system).
2. Check whether installed overvoltage dischargers are in order.
30.8 Testing the printer
1. Check the roll of paper in the printer and ensure that there are spare rolls
available.
2. Initiate the printer test and check the print-out for legibility and correct printing.
3. Check whether the events are correctly printed out.
You will find more information about the printer in document 008838. See chapter
'Applicable documents'.
