Wiring – Good Practices
Please observe these important suggestions when wiring the LR-911 reader – or any low-voltage products
or systems.
• Connect wires in this sequence:
First ...........ground connections.
Second.......general wiring – data lines, control lines.
Third..........power. (Be certain that all other wires are connected before applying power.)
• The LR-911 has, in effect, 3 separate ground connections –
black wire to the power supply’s negative,
blue wire to the panel’s data common, and
drain wire to the shield of the cable between reader and panel.
Do not connect these three wires together. Do not earth-ground any of these wires.
