Description
The Potter SignaLink™ Bridge is a fully supervised wireless bridge
designed to be attached to any non-explosion-proof dry contact sprinkler
monitoring devices. It removes the need to hard wire sprinkler devices
to each other, and operates on a 2.4 GHz frequency. Devices are able to
communicate with each other up to a maximum of 800’. All enclosures are
weather and UV resistant polycarbonate. There are no external antennas.
The antenna is incorporated into the circuit board of each device.
Transmitter Model WTX-M
The transmitter enclosure has a threaded nipple, O-ring and locking nut
for mounting directly to the conduit entrance of any dry contact device
not listed as explosion proof. The transmitter provides two ying leads
for connection to the normally open contacts of any listed dry contact re
alarm device. The connection is supervised for opens and shorts using the
supplied 5.1k ohm End Of Line Resistor. The transmitter does not latch,
it follows the status of the sprinkler switch it is connected to. The unit is
powered by two (2) AA size 1.5 volt Lithium Iron/Disulde batteries. The
device includes a cover tamper switch as well as an LED to indicate when
the battery meter has been reset. See g 1.
Receiver Model WRX-R
The receiver contains a fail safe dry contact output than can be monitored
by any UL listed re panel zone or monitor module. The receiver enclosure
has an opening for 1/2” conduit. The receiver follows the status of the
transmitter so there is no reset switch, no sounder and no need for human
intervention. The receiver can be powered by the auxiliary power of the
re panel or UL 864 or UL 1481 listed 24 VDC supply with regulated
limited power output and battery backup. See ordering information on
page 10 for optional power supply. The receiver contains Individual
LEDs for; Power, Alarm/Supervisory, transmitter or repeater trouble,
Tamper, Communication Error, Low Battery and EOLR trouble to aid in
troubleshooting. See g 2.
Repeater Model WR
The repeater can be powered by one 3.6 volt D size Lithium Thionyl
battery or by the auxiliary power of the re panel or UL 864 or UL 1481
listed 24 VDC supply with battery backup. See ordering information on
page 10 for optional power supply. Per UL 864, if the repeater is powered
by batteries it must be dedicated to only one transmitter repeater pair. If the
repeater is powered by a listed supply it can support multiple transmitters.
The device includes a cover tamper, pry-o tamper switch, an LED to
indicate when it is transmitting, and an LED to aid in resetting the battery
meter, see g 3. For mounting to a post, use the optional post mounting kit
#0090221, see g 6.

Wireless Supervisory System
Site Survey/Setup Tool
The Wireless Setup Tool, model WST, is required for installation. See document #5401608 for more information regarding the setup tool. The tool is
used to check signal strength between all devices among other features. It is strongly recommended a site survey be conducted before installing the
wireless system. Failure to conduct a thorough site survey may result in communication errors later. The installer should determine where the transmitter
will be located. The receiver shall be mounted adjacent to the re panel. Typically, higher on a wall allows the receiver to “see” over obstructions and
provides a better path for the wireless signal. Keep in mind that the metal framing of a drop ceiling can aect the signal. The receiver should not be
installed near a large metal object as that could attenuate the signal. After identifying the location of the transmitter and receiver the installer should
walk around and in between the areas where the transmitter and receiver will be installed and look for possible obstructions to the wireless signal such as
metal fences, metal doors, wired glass and other metal objects. The installer should investigate to determine if the normal business processes throughout
the day might result in an obstruction between the transmitter and receiver. Possible obstructions could include the movement of equipment or fork
trucks, trac patterns for shipping, deliveries, trash pickup, food trucks, etc.
In addition to the above-mentioned scenarios, there is the possibility of interior building changes such as the relocation of metal le cabinets or shelving
or changes to the interior of the building that could aect the signal path. Document and keep as much information about the site survey as possible.
This will come in handy if someone must return for troubleshooting later. The notes may be helpful to determine what, if anything, has changed. When
bidding wireless jobs, it may be wise to consider that a repeater may eventually be needed.
The setup tool can be used to measure the strength and quality of the communication signal between all Potter wireless devices on the network. The
setup tool also allows the user to pair devices together, check battery life, add or delete repeaters, check trac on the default communication channel,
change channels and other functions. Wireless devices communicate on a specic channel on their selected frequency. Heavy trac on a channel can
lead to communication issues. The setup tool allows the installer to check for trac on the default channel and if necessary, to change the channel.
Potter wireless devices are factory set on channel 4. The installer may want to inquire if a wireless network is running at the facility and what channel
it is and change the Potter devices to a dierent channel.

Wireless Supervisory System
Device Pairing
The Potter wireless devices do not require any programming to operate. The only requirement is to pair together the devices that will communicate with
each other on the network to form a wireless system. This can be accomplished in one of two ways.
1. Use the Wireless Setup Tool on a laptop to enter the unique MAC ID of the transmitter and receiver that will be communicating with each other
on the wireless system. This process is described in the literature with the Setup Tool.
2. Cycle the power on the transmitter and receiver to put them in Learn Mode and then use the cover tamper switches on each to force them to send
their MAC IDs to each other. This process is described in the following section.
Important: Please read all the pairing steps BEFORE starting the process so you are familiar with it. Have both devices to be paired on a workbench
and have the necessary power supply/batteries ready to be connected/inserted.
The transmitter and repeater (if used) must be paired to the receiver to allow them to communicate with each other. The transmitter and repeater are
individually paired to the receiver. First pair the transmitter to the receiver. If repeaters are used, they will be individually paired one at a time to the receiver
after the transmitter pairing is complete.
Note: When power is rst applied to the devices, they go through a power-up cycle for about 3 seconds. All the LEDs on the devices will ash during this
time. After the 3 second power-up process, they are in Learn Mode for about 40 seconds. The pairing must occur during the Learn Mode.
IMPORTANT NOTICE REGARDING BATTERY LIFE
Battery operated devices spend most of their time in battery conservation mode. They only communicate to indicate an event or for the required
periodic supervision signal to the receiver. The receiver then puts the device back into conservation mode. Do not leave batteries in a device that is not
installed as part of an active system with an operating receiver. If a battery powered device does not receive conrmation from the receiver, the device
will continuously try to contact the receiver resulting in a low battery alert within a few days. If devices are not immediately going to be installed after
pairing, remove the batteries after pairing. The pairing will remain after battery removal.
LED Conditions in Learn Mode:
• On the receiver, only the WTX-M & WR LEDs will ash simultaneously. See g. 2, page 7 for location of LEDs.
• On the transmitter, only the BATT RST LED will ash. See g. 1, page 7 for location of LEDs.
Pairing Process:
1. Apply 24 VDC to the receiver.
2. Install the batteries in the transmitter/repeater (or apply 24 VDC power supply to the repeater if used).
3. Wait about 3 seconds until only 1 LED on the transmitter is ashing and only 2 LEDs on the receiver are ashing.
4. SLOWLY press the transmitter/repeater cover tamper switch holding it down long enough each time to make sure the 2nd LED on the transmitter /
repeater turns on each time the switch is pressed.
5. After the 5th activation of the switch/lighting of the 2nd LED, both LEDs on the transmitter/repeater will ash rapidly for a few seconds.
6. The devices should now be paired. Verify a successful pairing by releasing the tamper. The WRX-R should display a tamper error for that transmitter/
repeater.
The Learn Mode LEDs will continue to ash until the Learn Mode times out. There is no need to do anything during this time. When the Learn Mode LEDs
stop ashing, the devices are ready to be put in service. If a repeater needs to be paired, remove power from the receiver and start over at step 1 above. The
devices will remain paired together even after power is removed. There is no need to re-pair them after removing power and re-applying power for eld
installation.
If multiple repeaters are paired, the technician should record on each Repeater whether it was the rst, second or third repeater paired to aid in
troubleshooting later. Repeaters must be installed in the order in which they were paired. Repeater # 1 should be closest to the receiver and repeater #3
is closest to the transmitter.

Wireless Supervisory System
WRX-R - Receiver
The Receiver provides a dry contact output allowing it to be monitored by any zone or monitor module of any re panel as just a dry contact input.
The Receiver follows the status of the transmitter so it does not have to be manually reset after activation. When the device connected to the transmitter
restores to normal, the transmitter will send a restoral signal to the receiver causing it to restore to normal.
The Receiver provides three terminals for connection to the FACP, see g 2. Connect the EOLR from the FACP across the COM and EOLR terminals.
Connect the zone from the FACP across the COM and NO terminals. The EOLR and NO terminals are connected internally by a failsafe relay contact
that is normally energized closed. In the event of a trouble signal from the transmitter or repeater, loss of communication or loss of power to the
Receiver, that relay will drop out and initiate a trouble at the FACP. An alarm or supervisory signal from the transmitter will result in a relay closing
across the COM and NO terminals initiating an alarm or supervisory condition on the FACP depending how the panel is programmed.
Devices do not need to be re-paired when batteries are replaced or if the unit is powered down.
If a WR must be replaced, the wireless Setup tool must be used to remove the MAC address of the old device from the system. Then the new device
can be paired using either the Setup tool or the cover tamper switch.
WTX-M - Transmitter
The Transmitter is designed to be connected to any product not classied as explosion proof that provides a dry contact output. Remove the locknut
from the threaded nipple of the Transmitter, make sure the O ring is properly installed on the nipple and insert the nipple through the ½” conduit opening
of the device. Install the locking nut on the inside of the device and tighten rmly in place.
Connect the two wire leads of the Transmitter and the supplied 5.1k ohm End of Line Resistor across the normally open contacts of the device to be
monitored. Polarity is not a concern.
Installation
Maximum line of site communication is approximately 800 feet between devices. Metal objects can greatly reduce signal strength. A chain link
fence can almost completely block a signal if the fence is too close to the transmitter, repeater or receiver. Metal shelving, walls with metal framing,
metal doors, windows with wired glass, vehicles, all have an eect on the ability of the wireless signal to pass through.
For best transmission/reception of wireless communication, it may help to attempt to install the Transmitter in a position so that it is not completely
obstructed from metal. Rotating the Transmitter enclosure so that it can “see” around the metal Potter device, pipe, valve, etc. may help communication.
When mounting the repeater to a post, it may be necessary to rotate the Repeater on the post to achieve best signal reception/transmission.
Installation shall be performed by qualied personnel and in accordance with all local and national codes and ordinances and the approval of the local
AHJ.
CAUTION
Wireless devices shall not be used as the primary initiating device to activate water or agent suppression systems. Wireless devices may experience
communication or interference issues which could result in an unintended discharge or a failure to discharge.
• The receiver needs to be connected to a latching trouble zone and re-sound every 4 hours (if silenced). The receiver cannot be monitored by
a zone that uses alarm verication.
• The receiver shall be mounted adjacent to the re panel.

Testing
1. Activate the sprinkler switch. The Alarm/Supervisory relay on the Receiver shall change states within 10 seconds.
2. Restore the sprinkler switch back to the normal state. The Alarm/Supervisory relay on the Receiver shall restore back to normal within 10 seconds.
3. Disconnect a wire from the Transmitter to the sprinkler device. The trouble relay on the Receiver shall change states within 10 seconds.
4. Reconnect the wire to the sprinkler device. The Trouble relay on the receiver shall restore to normal within 10 seconds
5. Remove the cover on the Transmitter allowing the cover tamper switch to activate. The trouble relay on the Receiver shall change state within 10
seconds.
6. Depress the cover tamper on the Transmitter. The trouble relay on the Receiver shall restore to normal within 10 seconds.
7. Remove the battery from the Transmitter. The trouble relay on the Receiver shall activate within 84 seconds.
8. Reinstall the battery in the Transmitter. The trouble relay on the Receiver shall restore to normal within 10 seconds.
9. Replace the cover on the Transmitter and make sure the Receiver is in a normal condition.
10. Repeat steps 5 and 6 for any repeaters.
Note: The times noted above are the maximum times allowed. Actual times will be signicantly less with the possible exception of the missing battery test.
Battery status is checked every 84 seconds so it depends where in that 84 second timing cycle the battery was removed.
WR-Repeater
Per NFPA 72, if the repeater is powered by an external power supply, the repeater is allowed to support multiple transmitters and receivers. Although
the repeater may support more than one receiver, it can only be paired to one receiver. This selected receiver will display the status of the repeater.
If a repeater is powered by a battery, that repeater shall only serve one transmitter/receiver set. This is so that in the event that if the repeater loses its
sole source of power, it does not aect more than one transmitter/receiver set.
The Wireless Repeater is designed to be mounted to a wall or a post using the optional post mounting kit, see g. 6. When installing the Repeater
outdoors, it may be necessary to install the device so that it is above vehicular trac.
When mounting to a wall make sure the surface is at enough to activate the pry-o tamper on the back of the unit. When mounting to a post, follow
the instructions that come with the post mounting kit to ensure that the pry-o tamper on the back of the Repeater will operate correctly.
There is a weatherproof rubber plug in the conduit entrance on the bottom of the Repeater enclosure. When powering the Repeater with batteries, leave
the weatherproof plug in place. When using an external power source, remove the plug to connect the conduit. The Repeater can be powered by an on-
board battery or an external power supply. It is shipped from the factory in the External Power mode. To switch to battery power, remove the 4 screws
holding the cover in place and move the jumper from Com and Ext Power to Batt & Com. See g. 3.
For class A operation, the repeater must be powered by a UL 864 or 1481 listed supply with battery backup. Every repeater must have a backup repeater
to provide dual communication paths and each repeater must have it’s own UL864 or 1481 battery backed up power supply so the loss of one power
source only aects one repeater. If the system would normally require one repeater, two must be used. If the application would normally require two,
four must be used, etc.
Please note, only 3 repeaters can be paired to a receiver. If additional repeaters are required for class A operation, the additional repeaters would be
paired to subsequent receivers.
After the devices are paired and installed, the signal strength between all devices should be checked using the Wireless Setup Tool. The signal
strength between all devices shall be above a minimum of 53%. Anything below 53% may result in communication errors. See document 5406108
for information about the setup tool.
Battery Information
The batteries will last 1 year under normal use. When the battery level reaches a point where there is a minimum of seven days of power left, the
Transmitter and/or Repeater if powered by batteries will transmit a low battery signal to the Receiver. At this point the batteries should be replaced
as soon as possible with the correct batteries. The batteries may last longer than 7 days from the initial low battery signal. Additional life depends on
temperature, signal strength and number of transmissions. It is possible to determine remaining battery capacity using the Potter Setup Tool.
Testing of the wireless devices shall be conducted upon completion of the installation and periodically thereafter in accordance with the testing
requirements of the devices they are monitoring, applicable NFPA codes and ordinances and/or the authority having jurisdiction. (Manufacturer
recommends quarterly or more frequently)

SignaLink™Bridge
Wireless Supervisory System
After replacing all of the batteries with ones that are correct and fully charged, the battery meter must be reset to prevent false low battery signals.
Important: Please read these steps before starting the process for familiarization purposes.
Note: Immediately after installing new batteries, the device goes through a power-up cycle for approximately 3 seconds. All LEDs on the device
will ash during this time. After the power-up process, the device is in Learn Mode for approximately 45 seconds. During this time, the BATT
RST LED will ash. DO NOT interact with the device while any LEDs are ashing.
Reset Procedure:
1. Install new batteries that are the correct model and charge.
2. Wait until all LEDs have stopped ashing, approximately 50 seconds after new batteries have been installed.
3. SLOWLY press the cover tamper switch, pressing down until the BATT RST LED ashes once, then release the cover tamper switch.
4. Perform step 3 ve times. After the 5th ash, the LED will ash rapidly a few times and then go out.
The Battery Meter is now reset. The wireless setup tool can be used to verify the meter was reset successfully
It is not necessary to re-pair devices after replacing the batteries.
Battery Meter Reset Procedure
DO NOT RECHARGE, OPEN, CRUSH, HEAT ABOVE 212°F
(100°C), OR INCINERATE. KEEP BATTERY OUT OF REACH
OF CHILDREN AND IN ORIGINAL PACKAGE UNTIL
READYTO USE. DISPOSE OF USED BATTERIES PROPERLY.
REPLACE BATTERY WITH BATTERIES DESCRIBED
ABOVE. USE OF ANOTHER BATTERY MAY PRESENT A
RISK OF FIRE OR EXPLOSION.
CAUTION
Do not reset the battery meter without replacing the batteries.
By law, these batteries cannot be shipped by air.
Maintenance
No maintenance is required other than replacing of batteries as needed. See the battery replacement instructions above.
CAUTION
If the batteries in a battery powered device are not replaced in a timely manner after the device sends a low battery signal, that device will eventually
quit communicating. At that point it will not be able to send a low battery signal or any other signal so the only visible indication will be the COM
ERROR LED on the receiver.
DO NOT leave batteries in a device that is not installed as part of an active system with an operating receiver. If a battery powered device does not
receive conrmation from the receiver, the device will continuously try to contact the receiver, resulting in low batteries in a matter of a few days. If
devices will not be immediately installed after pairing, remove the batteries after pairing. The pairing will remain after battery removal.
