Note: Do not use 000 as an address. An address of
000 removes all association knowledge, reverts
the sensor to a low-power hibernation mode,
and sends a disassociation request to the
receiver.
3. Record the address and location of the receiver and
sensor pair.
Observing the Receiver for Readiness to
Associate
After initial power up, the receiver conducts a channel scan
for 20 seconds. During this time, the receiver selects from
16 available channels the clearest channel on which to
operate. LED1, LED2, and LED3 flash rapidly in succession
(round-robin style) while the channel scan is in progress,
as shown in part 1 of the illustration.
Important: Do not attempt association (leave the
insulation strip in place) until the channel
scan is finished.
After the channel scan is finished, LED3 begins blinking
(one-blink pattern) to show that the receiver is ready to be
associated with a sensor (see part 2 of the following
figure).
Associating the Sensor to the Receiver
To associate the sensor to the receiver:
1. Remove the sensor cover by firmly pressing the thumb
tab at the bottom of the cover and pulling the cover
away from the back plate.
2. Verify that the sensor is set to the sam
e address as the
receiver it is to be associated with.
3. Power the sensor by removing
the insulation strip from
between the two batteries.
Association is autom
atically initiated between the sensor
and the receiver. When LED3 on the receiver stops
blinking, association has been established.
If the first association attempt is unsuccessful, the sensor
automatically re-attempts association with the receiver
every 10 minutes.
Note: An associated sensor that has lost communication
with the receiver will transmit an association
request every 50 minutes. You can manually
initiate association (see “Manual Association
(Wireless Controls),” p. 120”).
Testing Signal Strength and Battery Status
To verify that the association process was successful and
that the batteries have adequate charge:
1. Firmly press and release the Test button on the bottom
of the sensor (as illustrated below).
2. For model WZS, view LED1, LED2, and LED3 to
deter
mine the signal strength. View LED5 to determine
the battery status (see the following figure for model
WZS sensors).
Note: Th
e LEDs will turn Off after 5 seconds to
conserve battery strength.
For model WDS, determine the signal strength and
battery status by viewing the symbols on the sensor
display (see the following figure for model WDS
sensors).
3. Record the results in your co
mmissioning statement.
Note: For more information, see “Testing Signal Strength
(Wireless Controls),” p. 118 and “Testing Battery
Status (Wireless Controls),” p. 118.
