ZFR1810 Wireless Field Bus Coordinator Installation Instructions

Wireless Signal Transmission Considerations
Line-of-sight transmission ranges between a
ZFR1810 Coordinator, ZFR1811 Router, and/or a
WRZ Series 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. The effective transmission
range for outdoor applications varies based on
environmental conditions.
Mounting the Base
The ZFR1810 Coordinator can be surface mounted
using the four No. 6 Trade Size self-tapping, pan-head
screws supplied.
To mount the ZFR1810 Coordinator base with screws:
1.
Remove the ZFR1810 Coordinator from the
mounting base (Figure 2).
2.
Use the mounting base as a template, and place
the mounting base against the mounting surface.
3.
Drill pilot holes at the marked locations and secure
the mounting base to the surface with the four No.
6 Trade Size screws supplied.
4.
Mount the antenna and connect the antenna cable
to the ZFR1810 Coordinator. See
5.
Reinstall the ZFR1810 Coordinator housing to the
mounted base.
Assembling the Antenna
If mounting the ZFR810 Coordinator in a control panel,
choose a location on the top side of the control panel
for placement of the antenna. Ensure that the selected
location has line-of-sight to two or more ZFR1811
Routers.
Use Figure 3 and the following steps to assemble the
remote-mount antenna:
1.
Remove the knock-out tab on the enclosure/panel
box or drill a 7/8 in. diameter hole in the desired
location on the top of the enclosure.
2.
Insert the round bushing into the hole in the
enclosure.
3.
Insert the hexagonal bushing into the antenna
mounting bracket.
4.
Thread the antenna cable through the hexagonal
bushing.
5.
Insert the base of the antenna into the hexagonal
bushing and press until it snaps securely in place.
6.
Thread the antenna cable through the round
bushing at the top of the panel.

IMPORTANT:
Do not overtighten the mounting
screws. Overtightening the mounting screws may
damage the mounting base or mounting surface.
IMPORTANT:
Use the antenna provided. Do not
alter the antenna in any way or use another
antenna. Do not modify the antenna cable in any
way.
IMPORTANT:
Minimum bend radius for the
antenna cable is 25 mm (1 in.). Any bend with a
smaller radius may damage the cable.

1. Remove receiver housing by
pressing the locking tabs in at
the slots in the mounting base to
release the receiver from base.
2. Use the mounting base
for screw hole template.
3. Insert the four No. 6 screws into
mount holes on mounting base and
tighten them evenly to the surface.
4. Reinstall receiver
housing by aligning locking
tabs with slots on mounting
base and pressing housing
until it locks on to base.
