Manual Association Process
If an association was previously established between a WCI and a sensor and needs to be re-
established, the manual association process may be used. The process for the WCS-SO/SCO
2
differs
slightly from other sensors.
WCS-SO, -SCO
2
, -SB/R
To activate this process from a blank screen or an error screen, push the UP arrow on the WCS keypad.
The association process will be repeated as the display shows rotating segments.
Note: Pressing the UP arrow will repeat the joining/associating process from the last point of failure. In
other words, if there is an E2 (not in a network), the sensor will start by looking for an open
network to join. If there is an E1, the sensor will look for a unit. If there is an E8 or E9, the sensor
will request association with the unit. The process continues until a step fails or the unit provides
system data to display.
WCS-SB/SD
To activate this process, push the center button twice on the WCS keypad. The association process will
be repeated.
Note: Pressing the center button twice will repeat the joining/associating process from the last point of
failure. In other words, if there is an E2 (not in a network), the sensor will start by looking for an
open network to join. If there is an E1, the sensor will look for a unit. If there is an E8 or E9, the
sensor will request association with the unit. The process continues until a step fails or the unit
provides system data to display.
Disassociation
If any address—group/net, unit controller, or sensor # — is changed in a sensor that is associated with a
controller, the sensor will transmit a request for the controller to disassociate the sensor immediately.
If a controller does not receive any messages from a sensor for 34 minutes, it will disassociate that
sensor. Only after a sensor has been disassociated can the controller accept association from a
replacement sensor.
Replacing a Failed WCS
To replace a failed WCS:
1. Remove failed sensor from the wall.
2. Disassociate the sensor from the unit controller by using one of the three methods described below.
(A. is the recommended way to disassociate the sensor when possible)
a. If the sensor is still communicating with the unit controller, change any part of the sensor
address (GRP, NET, UC, SENSOR#). The sensor will immediately send a request to the unit
controller to disassociate, and it will display E1. Proceed to Step 3. (If in doubt that this method
worked, or the sensor is not communicating with the unit controller use method B).
b. Remove the batteries from the failed sensor and let the association between old unit controller
and sensor expire on it's own. Proceed to Step 3.
Note: If you use this method to disassociate the old sensor, an E9 error code may display on the
new sensor. This error code will be displayed for 34 minutes. After 34 minutes, the error
code will clear and the new sensor will automatically associate to the unit controller.
c. An alternative method to Step 2b will speed up the disassociating process.
1. Set the UC rotary address to 000 and wait 30 seconds.
2. Power down UC and set UC address to correct setting.
3. Restore power to UC. Wait for one minute before attempting to associate the sensor.
4. Confirm network is open.
5. Confirm WCS address settings are correct (GRP, NET, UC, Sensor#).
6. Press center button on sensor twice to force transmission. Sensor should join the network
and associate with the UC.
3. On the new sensor, set the address and configuration to match the original sensor.
