FX-WRZSST-110 Wireless Sensing System Tool Installation Instructions
3
Note:
If an FX-ZFR1811 Wireless Field Bus Router is
used in the final installation to extend the operating
range, place the FX-WRZSST-110 Tool in the location
where the FX-ZFR1811 Router is to be located. Use
the FX-WRZ Series Sensor to verify the intended
sensor location, then use the FX-WRZ Series Sensor
to stimulate and verify the intended FX-WRZ7850
Receiver location.
For an FX-ZFR Series Wireless Field Bus System,
place the FX-WRZ Series Sensor in the desired
location for an FX-ZFR1811 Router, and place the
FX-WRZSST-110 Tool in the desired location for an
FX-ZFR1811 Router or FX-ZFR1810 Coordinator.
6.
Turn on the power switch of the test FX-WRZ
Series Sensor and allow it to establish
communication with the FX-WRZSST-110 Tool.
When communication is established, the
Light-Emitting Diode (LED) showing RF signal
strength on the FX-WRZSST-110 Tool blinks.
If communication is not established within
15 seconds, press the manual occupancy override
button on the FX-WRZ Series Sensor to force
another communication attempt.
7.
After the FX-WRZ Series Sensor establishes
communication with the FX-WRZSST-110 Tool,
press the manual occupancy override button for
5 seconds and release to force the sensor into
Rapid Transmit Mode (RTM).
8.
Hold the FX-WRZSST-110 Tool in the desired
location and record the number of times the
RF signal strength LED blinks over the course of
10 seconds.
If the RF signal strength is weaker than Good,
move the location of either device until an Excellent
or Good RF signal strength is indicated.
Move on to the next location, and repeat Step 1
through Step 9 as necessary.
9.
When testing is finished, turn off the battery switch
on the FX-WRZSST-110 Tool and turn off the
power switch on the test FX-WRZ Series Sensor.
Operation
Wireless Signal Strength
The RF signal strength LED indicates the strength of
the RF wireless signal between the sensor and its
associated sensing system receiver, expressed as
Excellent, Good, or Weak. The FX-WRZSST-110 Tool
has an RF signal strength LED that blinks off one, two,
or three times for every RF transmission to indicate the
RF signal strength between the sensor and the tool, or
the router/coordinator and the tool. See Table 1.
Rapid Transmit Mode (RTM) and RF Signal
Strength LEDs
Normally, the sensor transmits every 60 seconds;
however, pressing the manual occupancy override
button on the FX-WRZ Series Sensor for 5 seconds
and then releasing it forces the sensor into RTM. In
RTM, an FX-WRZ Series Sensor sends an RF data
transmission once every 10 seconds. The sensor
remains in RTM for up to 30 RF transmissions. After
each RF transmission, the RF signal strength LED of
the sensor flashes (LED off to on) to indicate the RF
signal strength between the sensor and FX-
WRZSST-110 Tool. The
FX-WRZSST-110 Tool blinks (LED on to off) to indicate
the wireless RF signal strength.
