6. Observe the polarity indicators that are molded into
the cover.
7. Install two batteries (of t
he type specified in “Battery
Type (Wireless Controls),” p. 119 ) in the battery-holding
slot that is molded int
o the sensor cover.
The sensor has been designed to prev
ent damage if the
batteries are installed backwards, to reduce the potential
for injury.
Manual Association (Wireless Controls)
Before attempting manual or automatic association, the
receiver must indicate readiness to associate (one blink
pattern of LED3 on receiver). Refer to “Observing the
Receiver for Readiness to Associate,” p. 78.
At any time, the manual association method can be used
to associate the receiver with the sensor. If an association
was previously established between a receiver and a
sensor and needs to be re-established, the manual
association process may be used. If an association has not
yet been established, the automatic association process is
recommended (see “Associating the Sensor to the
Receiver,” p. 78).
8. Using a small screwdriver, set the three rotary address
sw
itches (Figure 33, p. 77, locations S1, S2, S3) on the
receiver to an address between 001 and 999.
Notes:
• A
n address can be changed without powering
down the receiver or sensor.
• An address can be changed at any time after initial
association has been established.
9. Set the three rotary address switches (Figure 33, p. 77,
locations S1, S2, S3) on the sensor to the
same address
as the receiver.
10. Record the address and location of the receiver and
sens
or pair.
• Af
ter verifying that the receiver and sensor are
powered up, press the Test button on the sensor to
establish that the signal strength (“Testing Signal
Strength (Wireless Controls),” p. 118) and the
battery life “Testing Battery Status (Wireless
Controls),” p. 118) are adequate for proper
functioning.
Disassociation (Wireless Controls)
The receiver disassociates from the sensor (by removing
all stored association information), conducts a channel
scan, and restarts itself, if any of the following are true:
• The receiver address is c
hanged from its current
setting (001–999)
• The receiver receives a disassociation notification
from its
associated sensor
• The receiver does not recei
ve a communication from
its associated sensor within 50 minutes.
• The sensor and receiver are associated and
communicating
at the time the sensor is set to 000 and
the Test button is pressed.
Note: A disassociated sensor will transit an association
r
equest every 10 minutes.
Sensor/Receiver Compatibility (Wireless
Controls)
Version 1.5 (p/n X13790854 and X13790855) and higher
receivers are compatible with all sensors models and
support all functions. Receivers released prior to version
1.5 are compatible with only model WZS.
Replacing a Failed Sensor or Receiver
(Wireless Controls)
Note: Receivers ship installed on the unit. To remove the
receiver, press in the retention tabs on the
underside of the receiver enclosure (see Figure 32,
p. 77) and push upward.
To replace a failed sensor or receiver:
11. Confirm that the device is disassociated
(see Tab l e 45
and Tab l e 46, p. 11 8 ).
12. Set the rotary address switc
h of the new device to
match the address of the remaining sensor or receiver.
Note: Th
ere is no need to remove power from the
remaining device.
13. Apply power to the new device. Association between
the new and
the remaining devices will automatically
occur.
Note: When
replacing a WDS sensor, the receiver
(version 1.5 or higher) will automatically configure
the sensor to match the last stored configuration, if
the sensor has not been placed into configuration
mode and the factory default configuration is still
valid. If the sensor configuration does not match
the desired system features, it can be manually
configured (see “Manual Association (Wireless
Controls),” p. 120).
Servicing and Testing (Wireless Controls)
If the wireless sensor system is not working as expected,
use the tools and procedure described in this section.
Servicing and Testing Tools (Wireless Controls)
No special tools or software are necessary to service and
test the wireless sensor system. Test the system by using:
• The LEDs on the receiver, LEDs on
the model WZS
sensor, and the display on the model WDS sensor
