End of Line (EOL) Resistors
The 330 Ohm EOL (End of Line) resistor provided in the accessory bag must be inserted between the NA and
NB terminals of the first and last modules on the RS-485 network. These are the modules physically located at
the ends of the RS-485 network cabling.

Backup Battery
PoE models only
It is recommended that a minimum of a 7Ah battery is used as the main backup battery. From the accessory
bag provided, connect the RED and BLACK battery termination wires to the B+ and B- plugs. Connect the
spade terminals to the battery as shown below. Connection of the battery in reverse will not damage the
Controller but will cause the battery fuse (5A resettable fuse) to open, requiring the resetting by removal of all
connections to the B+ and B- plugs for approximately 30 seconds.

Warning
: Only attach standard lead acid batteries. Do not connect the battery wires or B+ and B-
plugs of the Power Supply to any other ancillary device (siren, lock or mag clamp etc). An incorrect
connection may cause erroneous faults or serious damage to the Controller and will VOID ALL
WARRANTIES OR GUARANTEES.
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 zone associated with the address assigned to the Controller.
