Backup Battery
A battery backup must be connected to the module network to provide a monitored supply. The battery plays
an important role in power conditioning and provides a continuous source of power in the event of a power
outage.
It is recommended that a minimum of a 7Ah battery is used as the main backup battery.
From the accessory bag provided:
1.
Connect the
red
and
black
battery termination wires to the B+ and B- plugs.
2.
Connect the spade terminals to the battery as shown below.
Connection of the battery in reverse will not damage the power supply, but will cause the battery circuit to
disconnect until correct connection is made.

Warning
:
⦁
Only attach standard lead acid batteries.
⦁
Do not connect the battery wires or B+ and B- plugs of the module to any other ancillary device (siren,
lock, mag clamp, etc.).
⦁
An incorrect connection may cause erroneous faults or serious damage to the module and will

The battery test procedure uses a special algorithm to prevent deep discharge and increase battery
endurance. A dynamic battery test is performed every ten minutes when mains power is present, and a battery
condition alarm will be generated if the battery is either disconnected or shows poor capacity. Battery fault
conditions will activate the battery trouble input associated with the address assigned to the power supply.
In addition to the dynamic battery test procedure, the power supply performs a battery presence test every 60
seconds, which determines whether the presence of a backup battery is detected. Similarly, if no backup
battery is detected a battery condition alarm will be generated and the battery trouble input associated with
the address assigned to the power supply will also be activated.
To comply with EN 50131-1 only one battery can be connected and monitored per system. If more capacity is
required a single larger battery must be used.
