WRZ-SST-100 Wireless Sensing System Tool 1
Applications
The WRZ-SST-100 Wireless Sensing System Tool is a
lightweight, portable, wireless receiver designed to
receive wireless data transmissions from WRZ-TTx
Series Sensors in one-to-one sensing system site
survey applications. It also serves as a signal test
receiver or site survey tool prior to installing a ZFR1800
Series Wireless Field Bus System.
Use the WRZ-SST-100 Sensing System Tool prior to
installation to verify the optimum locations for
WRZ-TTx Series Sensors and WRZ-7840-0 Receivers
in wireless room temperature sensing system
applications; or for ZFR1810 Coordinators, ZFR1811
Routers, and WRZ-TTx Series Sensor in wireless field
bus applications.

Installation
Transport the WRZ-SST-100 Wireless Sensing System
Tool in the original container to minimize vibration and
shock damage to the receiver.
Verify that all the parts shipped with the receiver:
• one WRZ-7840 Receiver with two magnets
attached
• one battery pack with two magnets attached
• two alkaline batteries
• one installation instruction sheet
This equipment has been tested and found to comply with
the limits for a Class A digital device pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when
this equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause
harmful interference, in which case the user will be
required to correct the interference at his/her own
expense.
RF Transmitters: Compliance Statement (Part 15.19)
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation.
Warning (Part 15.21)
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur du
Canada.
RF Transmitters: Industry Canada Statement
The term IC before the certification/registration number
only signifies that the Industry Canada technical
specifications were met.
Le terme « IC » précédant le numéro d'accréditation/
inscription signifie simplement que le produit est conforme
aux spécifications techniques d'Industry Canada.
Section 5.5 of RSS-210
This device has been designed to operate with an antenna
having a maximum gain of 2 dB. Antenna having a higher
gain is strictly prohibited per regulations of Industry
Canada. The required antenna impedance is 50 ohms.
Cet appareil a été conçu pour fonctionner avec une
antenne d'un gain maximum de 2 dBi. En application des
réglementations d'Industry Canada, l'utilisation d'une
antenne de gain supérieur est strictement interdite.
L'impédance d'antenne requise est de 50 ohms.
Section 5.11 of RSS-210
To reduce potential radio interference to other users, the
antenna type and its gain should be so chosen that the
equivalent isotropically radiated power (EIRP) is not more
than that required for successful communication.
Pour réduire les interférences radio potentielles avec les
dispositifs d'autres utilisateurs, le type d'antenne et son
gain doivent être choisis de façon à ce que la puissance
isotrope rayonnée équivalente (PIRE) ne soit pas
supérieure à la puissance nécessaire pour une bonne
communication.

Issued February 26, 2009
Supersedes June 25, 2008
Installation Instructions 2
Do not drop the receiver or subject it to physical shock.
Detailed Procedure
Note: Ensure the power switches on the
WRZ-7840 Receiver and WRZ-TTx Sensor are set to
OFF before proceeding.
1. Set the TRANSMITTER ID and AREA DIP
switches on the WRZ-7840 Receiver and the
WRZ-TTx Sensor to the same address.
2. Install the batteries into the battery pack.
3. Connect the battery pack wire harness to the two
pin connector located under the TRANSMITTER ID
DIP switches on the back of the WRZ-7840
Receiver.
Note: Connecting a battery pack to the receiver
changes the WRZ-7840 Receiver into the
WRZ-SST-100 Tool.
4. Turn the battery pack switch to ON.
5. For a One-to-One wireless system, place the
WRZ-SST-100 Tool in the location where the
WRZ-7840 Receiver would be located, and place
the WRZ-TTx Sensor in the location you intend to
mount this device.
Note: If an MS-ZFR1811-0 Repeater is used in
the final installation to extend range, place the
WRZ-SST-100 Tool in the location where the
MS-ZFR1811-0 Repeater is to be located. Use the
WRZ-TTx Sensor to verify the intended sensor
location, then use the WRZ-TTx Sensor to
stimulate and verify the intended WRZ-7840
Receiver location.
For a ZFR1800 Series Wireless Field Bus System,
place the WRZ-TTx Sensor in a desired location for
a ZFR1811 Router and place the WRZ-SST-100
Tool in a desired location for a ZFR1811 Router or
ZFR1810 Coordinator.
6. Power on the test sensor and allow it to establish
communications with the WRZ-SST-100 Tool.
When communication is established, the Radio
Frequency (RF) Light-Emitting Diode (LED) on the
WRZ-SST-100 Tool blinks.
If communication is not established within
15 seconds, press the occupancy button on the
WRZ-TTX sensor to force another communication
attempt.
7. Once the sensor establishes communication with
the WRZ-SST-100 Tool, press the occupancy
button for 5 seconds to force the test sensor into
Rapid Transmit Mode (RTM).
8. Hold the WRZ-SST-100 Tool in the location
desired and record the number of blinks of the RF
LED every 10 seconds.
If the signal strength is less than Good, you may
have to move the location of either device until an
Excellent or Good signal strength is indicated.
Move on to the next location, and repeat Steps 1
through 9 as necessary.
9. When testing is finished, turn off the battery switch
on the WRZ-SST-100 Tool and the power switch
on the test sensor.
Operation
Wireless Signal Strength
RF signal strength LED indicates the strength of the
wireless signal between the sensor and the associated
sensing system receiver, expressed as Excellent,
Good, or Weak. The tool has an LED that blinks off
one, two, or three times for every transmission to
indicate the signal strength between the sensor and
tool, or router/coordinator and tool. See Table 1.
Rapid Transmit Mode (RTM) and RF Signal
Strength LEDs
Normally, the sensor transmits every 60 seconds;
however, pressing and holding the manual occupancy
override button on a WRZ-TTx Series Sensor for
5 seconds or more forces the sensor into RTM. In
RTM, a WRZ-TTx Series Sensor sends a data
transmission once every 10 seconds. The sensors
remain in RTM up to a total of 30 transmissions. After
each transmission, the LED of the sensor flashes (LED
off to on) to indicate the signal strength between the
sensor and WRS-SST-100 Tool. The WRS-SST-100
Tool blinks (LED on to off) to indicate the wireless
signal strength.
IMPORTANT: If there are other wireless mesh
networks in the area, ensure that the PAN Address
of the WRZ-7840 Receiver and WRZ-TTx Sensor
(set by the TRANSMITTER ID and AREA DIP
Switches) is different from the PAN ID of those
wireless mesh networks.
