System Operation when Battery Box is connected
·
The battery box will provide battery back up when the mains power fails to the XN120 unit.
·
The XN120 charges the batteries whilst it is mains powered.
·
Each XN120 main/expansion unit must have a separate battery box connected.
When the mains power fails the XN120 unit will continue to operate as normal until the batteries become
discharged. The XN120 unit is considered to be in
battery back up mode
at this time, it is not in power fail
mode.
When the batteries are discharged the XN120 unit will stop working, the XN120 is now considered to be in
power fail mode
.
!
If you switch off the XN120 unit whilst in battery back up mode it will not power back on until the mains power
is supplied. The XN120 will not start up in battery back up mode.
Power Fail Telephones
If the XN120 has power fail telephones connected (refer to the XN120 Getting Started Guide 991409-5 for
details of connecting power fails telephones and power fail options) they will become active when both the
mains power fails and the batteries are discharged i.e. when the XN120 is in power fail mode.
Battery Maintenance and Replacement.
The batteries should be replaced every 3 years to ensure the maximum battery back up duration (1 hour) is
available.
The maximum operating life of the batteries is 5 years, the battery back up duration will begin to reduce after 3
years.
The label on the front cover of the battery box should indicate the battery installation and replacement dates.
Follow the instructions in this guide when replacing the batteries.
Follow the instructions supplied by the battery manufacturer for disposal of the old batteries.
Replacing the fuse
Replace with the same type of fuse – 20mm 4Amp fast acting.
