Note: If lithium batteries are temporarily unavailable, alkaline
batteries can be used. However, alkaline battery life is
very short by comparison.
Notes: The battery life for model WDS may decrease with
extended LCD display activity.
Battery Installation
WARNING
Risk of Injury with Batteries!
Failure to follow handling instructions below could
result in severe injury.
• Do NOT install batteries backwards.
• Do NOT disassemble, charge, or expose batteries to
water, fire, or high temperature.
• Keep batteries away from children. If swallowed,
contact your local poison control center immediately.
WARNING
Prevent Injury!
Keep away from small children. If swallowed, contact
your local poison control center immediately.
1. Observe the polarity indicators that are molded into the
cover.
2. Install two batteries (of the type specified in
p. 100) in the battery-holding slot that is molded into the
sensor cover.
The sensor has been designed to prevent damage if the
batteries are installed backwards, to reduce the potential for
injury.
Manual Association
Before attempting manual or automatic association, the
receiver must indicate readiness to associate (one blink
pattern of LED3 on receiver). Refer to
Readiness," p. 43.
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 Sensor to Receiver," p.
1. Using a small screwdriver, set the three rotary address
switches (Figure 47, p.
receiver to an address between 001 and 999.
Note: An address can be changed at any time after initial
association has been established. It is not necessary to
power down the receiver or sensor.
2. Set the three rotary address switches

as the receiver.

for proper functioning.
Disassociation
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 changed from its current setting
(001–999)
• The receiver receives a disassociation notification from its
associated sensor
• The receiver does not receive 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
request every 10 minutes.
Sensor/Receiver Compatibility
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
Note: Receivers ship installed on the unit. To remove the
receiver, press in the retention tabs on the underside of
the receiver enclosure and push upward.
To replace a failed sensor or receiver:
1. Confirm that the device is disassociated (see
p. 98 and Table 39, p.
2. Set the rotary address switch of the new device to match
the address of the remaining sensor or receiver.
Note: There is no need to remove power from the
remaining device.
3. 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
