Power Connections and Options

Primary power for the 7847i/7847i-E is provided by the auxiliary power output of the control
panel 9.6V –13.8V, typical, or other external power source.
When calculating the total load on the auxiliary power output of the control panel,
must be budgeted for the 7847i/7847i-E. Under normal operating conditions, the unit will
not pull more than 20mA; however, it will draw 75mA during a transmission.
Connect the wires from the (+) and (–) terminals of the DC power source to terminals V+ and
GND on TB1 of the 7847i/7847i-E. Observe Polarity!
If using an external power source, connect GND from power supply to GND of the control
panel.

Ethernet Connections

1. For UL installations, the Cat. 5 Ethernet connection between the 7847i/7847i-E and the
router cannot exceed 12 feet with both the 7847i/7847i-E and the router located within
U L
the same room.
2. Use a Listed cable/DSL router suited for the application.
