12 Pairing a WOFS Transmitter to a WOFS Receiver
A Transmitter needs to be paired to a Receiver only once, at the time of installation. The pair will
remain paired thereafter, even after power loss, or during battery replacement. One Receiver can
be paired with (and can monitor) up to 8 Transmitters.
To pair a Transmitter and Receiver:
1. On the Receiver, press and hold the pairing button for 3 seconds. The status LED will start
flashing blue indicating “discovery” mode.
2. On the unpaired Transmitter (be sure the batteries have been installed), press and hold the
Status button for 3 seconds.
o On a previously-paired Transmitter, press and hold the Status button on the
Transmitter for more than 20 seconds, until the status LED rapidly flashes blue, then
continue with step two above.
3. Upon successful pairing, the Transmitter’s status LED and the corresponding Status LED on
the Receiver (number 1, or 2, 3, … through 8) will turn green or red (which indicates
successful pairing and current Transmitter status).
o Repeat this process to pair the next Transmitter.
o When pairing of the Transmitters is complete, press and hold the Receiver’s Pair
button for 3 seconds to take the Receiver out of “discovery” mode.
 Caution: If the Transmitter is blinking slowly (1 flash every 2 seconds), the
Transmitter is trying to pair with a different Receiver. The Transmitter must
first be unpaired with its previous Receiver. Follow the process for unpairing
the Transmitter from the first Receiver (see Section 13), and try pairing again
with the second Receiver.
4. It is possible to pair several Transmitters to the Receiver in a more streamline method.
Follow the steps below:
o Hold the Receiver’s Pair button down for at least 3 seconds to enter “discovery”
mode.
o Press and hold the Status button on the Transmitter that will be known as Transmitter
#1. Wait at least 5 seconds for the corresponding status LED to change color.
o Press and hold the Status button on the Transmitter that will be known as Transmitter
#2. Wait at least 5 seconds for the corresponding status LED to change color.
o Press and hold the Status button on the Transmitter that will be known as Transmitter
#3. Wait at least 5 seconds for the corresponding status LED to change color.
o Continue this process until all of the Transmitters are successfully paired. Then, Press
the Receiver’s Pair button for 3 seconds. This will turn off the Receiver’s “discovery”
mode.
o Each paired Transmitter should now have a lit LED on the Receiver, associated with
its Transmitter pair. To check that each have been properly assigned, open and close
the fiber optic loop, and see if the Receiver shows a changing green-to-red-to-green
LED next to the correct number for that transmitter. This will also validate that the
fiber optic loop has been installed correctly.
