Wiring to the control panel
Follow the procedure below to wire one or two
D8125MUX modules to the 9000 Series, and G Series
control panels. For the B9512G, B9512G-E, B8512G,
B8512G-E control panels, see the Control Panels
Installation and System Reference Guide.
The B600 Retrofit (ZONEX) module is
required to use the D8125MUX on the
B9512G, B9512G-E, B8512G, and
B8512G-E control panels.
Remove all power (AC and Battery) before
making any connections. Failure to do so
may result in personal injury and/or
equipment damage.
3.2.1
Disconnecting the Battery and Transformer
1.
Disconnect the battery by unhooking the positive
(red) battery lead from the battery.
2.
Unplug the transformer.
Reversed polarity damages the D8125MUX.
Make sure you wire the D8125MUX AUX
and GND terminals to the control panel.
