CAUTION: The power switch does not control DC input power.
3. See the transmitter’s operator’s manual for instructions on how to connect wires to the
transmitter.
4. Install an appropriately rated cable bushing or conduit in an unused conduit hub on
the bottom of the Beacon 410 housing.
5. Route the wires from the transmitter through the selected conduit hub into the Beacon
410.
6. Connect the wires from the transmitter to the appropriate channel’s
detector/transmitter terminal strip. See the transmitter operator’s manual for controller
terminal connections and wiring recommendations.
CAUTION: Do not route power and transmitter wiring through the same conduit hub. The
power wiring may disrupt the transmission of the transmitter’s signal to the
Beacon 410.
Figure 10 below illustrates typical transmitter wiring connections.
