Pairing Mode
Pairing is required to initiate and establish an RF communication link between each single WLS and a single WPMM or WDRR. The
WLS will be shipped from the factory with two identification labels (1) that are recommended to be completed and applied to the WLS
housing during the pairing mode. As there are up to 16 WLS devices that can be paired to a single WPMM or WDRR, these labels
will be used to identify the WLS in the sequence of #1 to #16. The initial WLS paired to the WPMM or WDRR will be Sequence #1; the
second WLS paired will be Sequence #2 and so on. If replacing a WLS that has been purged, as applicable(see section 6.5 of the
WPMM Installation and Technical Manual or Section 7.3 of the WDRR Installation & Technical Manual), identify the correct replacement
Sequence # on the identification labels.
Pairing steps when using a WPMM:
The battery will need to be activated in the WLS and proper power applied to the WPMM (green
LED illuminated) before proceeding with this pairing procedure. Once the pairing is completed, the WLS selected will only commu-
nicate with the WPMM it was paired to and no other device.
Step
Action
1
Completely read this procedure before starting in order to understand the timing of events that need to be performed.
2
WLS: Remove (if required) the two screws
on the housing cover (See Figure 11, page 21) of the WLS and locate the
function button
to be used in Step 4.
3
WPMM: Press the Function button
on WPMM (See Figure 12, page 21) for more than four seconds and less than eight
seconds at which time the green
and yellow
LEDs will be flashing which indicates to release the function button im-
mediately as it has entered the pairing mode.
4
WLS: Within a 30 second interval of Step 3, depress the WLS switch function button
(See Figure 13, page 21) and hold
depressed for more than one second and less than 12 seconds at which time the orange
LED turns on. While in pair-
ing mode, the orange led will flash on for 100 ms every second. The orange
LED flashes three times 100 ms on, 100 ms
off when pairing succeeds. If pairing does not succeed, the orange
LED will turn off and user will need to repeat steps
starting with Step 3.
5
WPMM: Successful pairing will be indicated by the green
and yellow
LEDs (See Figure 12, page 21) ceasing to flash
and remaining on for a few seconds before turning off. A short buzzer beep will also occur.
6
To confirm proper pairing between the WLS and WPMM: actuate the WLS actuator, actuate using the magnetic actuator
(WLS Non-Contact Switch only), or actuate the user-supplied switch for the WLS Single Switch Adapter, and the red LED
should illuminate along with a buzzer sound.
7
Record the WLS Sequence # on identification labels
and apply to the WLS housing in desired locations (See Figure 14,
page 21).
8
Repeat Steps 2-7 to add additional WLS units switches. Up to 16 WLS can be paired to a single WPMM.
