Battery maintenance
Batteries must be replaced periodically as recommended by the manufacturer. The
useful life of the battery is approximately 4 years. Avoid the total discharge of the
batteries.
Battery test fail
When the control panel indicates that the battery test has failed, check the following:
• That the battery leads are in good condition
• That the battery leads are connected securely and correctly at the battery and at
the panel
• That the control panel event log does not indicate a mains failure in the last
twenty-four hours
If the leads are in good condition, all connections are correct, and the control panel
continues to report that the test has failed twenty-four hours after the last mains
failure, then the batteries should be replaced immediately.
Replacing batteries
To replace the batteries, do the following:
1. Disconnect and remove the existing batteries from the cabinet.
2. Install and connect the replacement batteries using the bridge provided. Observe
correct polarity.
Always use the recommended replacement batteries (see “Connecting the batteries”
on page 24).
Dispose of used batteries according the European regulations and/or instructions
from local authorities.
