Fault Finding

Step 8

Step 7

Battery float charge
1. Switch multimeter to DC mA range
2. Remove red charge lead from battery 3. Connect test probes in series with removed charge lead and positive battery terminal
4. A double mA reading, failing to a single mA reading, should occur within 30 seconds
5. If a constant high or no mA reading occurs, replace battery

Auxiliary DC voltage
1. Connect probes across auxiliary DC supply
2. Reading obtained should be within 0.5VDC of battery charging voltage. Any variation +/- 1VDC may cause false alarms

Step 9

Step 10

Battery current normal (unset)
1. Switch multimeter to 20A DC range
2. Disconnect mains supply by removing panel pr 'spur' fuse
3. Reading ideally should not exceed 5% of battey capacity (7Ah = 350mA)

Battery current in alarm
1. Generate a full alarm condition
2. Reading ideally should not exceed 10% of battery capacity (7Ah + 700mA)

Step 11

Battery capacity test
1. Disconnect battery from control panel
2. Check battery terminals are clean
3. Connect battery tester leads red+ black-
4. Record ambient temperature, DC voltage and Ah capacity available
5. Replace battery when capacity falls below 65% (e.g. 7Ah replace below 4.55Ah)
