ZFR1811 Wireless Field Bus Router Installation Instructions

Wireless Signal Transmission Considerations
Line-of-sight transmission ranges between a
ZFR1810 Coordinator, ZFR1811 Router, and/or a
WRZ Sensor can be less than the maximum distances
shown in Table 1. The effective transmission range for
indoor applications varies because of wireless signal
absorption and reflection due to metal obstructions,
walls (or floors), and furniture found in typical building
interiors.
Wiring
Wiring Considerations and Guidelines
Wiring with an FEC or VMA16 Series Field
Controller
Connect the ZFR1811 Router to the field controller as
shown in Table 2. This connection provides both power
and communication to the ZFR1811 Router.
Note:
When using a field controller in a wireless field
bus network, ensure that the DIP switch for Address
128 is set to the ON position.

IMPORTANT:
Do not connect supply power to the
ZFR1811 Router before finishing wiring and
checking all wiring connections. Short circuits or
improperly connected wires may result in permanent
damage to the Router.
IMPORTANT:
Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations. The ZFR1811 Router is a
low-voltage (less than 30 VAC) device. Do not
exceed the ZFR1811 Router’s electrical ratings.
IMPORTANT:
Prevent any static electric discharge
to the ZFR1811 Router. Static electric discharge can
damage the ZFR1811 Router and void any
warranties.
IMPORTANT: Do not
connect the ZFR1811 Router
to the power supply before setting the PAN OFFSET
switches.
