Installing Remote Units
Read MODBUS address 40016. This will contain the remote ID of the next remote you will be
adding to the network. Label the next remote to be added with the value contained in address
40016. This is done to create a reference between the remote and the MODBUS map.
NOTE: The first 8 remote units correspond to Gateway LEDs 1 through 8.
Additional remotes will use LED 8 to display sensor events.
When a sensor event occurs, a heartbeat is missed, or the remote‟s
battery is low, the Gateway will light up the appropriate LED 1 through 8.
1. Loosen the 4 screws and remove the lid to the remote
enclosure. Take out the PC board and place it onto the
lid. Set aside for later.
2. Place 2 wraps of Teflon tape in a clockwise fashion
around threaded connection as shown.
3. Run sensor wires into the remote case, leaving a few
inches of extra wire outside of the case.
4. Attach the remote case to the sensor or conduit, leaving
the case opening face up.
5. Snap the battery into place on the back side of the pc board,
aligning the +/- as indicated below.
NOTE: Use only Tadiran TL-5903-S 3.6 volt Lithium batteries.(See
How to Install a Battery in the Remote.)
6. Replace the PC board into the casing, battery side down.

Section 50 00-02-0674
04-16-10 - 15 -
7. Trim wires and strip ends approximately 9/32 inch
minimum.
8. Place wire ends in slot and screw down until snug.
NOTE: Make sure wire connects directly to
the J301 terminal without looping the wire
inside casing.
9. Rotate the remote unit clockwise to 90° vertical
position.
10.Repeat steps 1-9 for each additional remote unit. Do
not replace lid until the remote has been activated
and is recognized by the Gateway.
NOTE: The sensor resistance must be less than 25K Ohm. If the sensor
is greater than 25K Ohm, excessive current will reduce battery life.
11.Follow the instructions for “Remote Activation”. Ensure the signal is recognized by the
Gateway before replacing the lid in the next step.
12.Replace the lid. Hand tighten all 4 screws, then tighten-to-snug in a cross pattern to
ensure even seating, as illustrated below.
IMPORTANT! In order to meet NEMA 4 requirements, ensure all 4
screws are used to hold the lid in place.

Learn Operation
NOTE: After performing the Learn Operation, you will want to reset the
heartbeat counters so that accurate statistics can be recorded. Use the
PC to send a command to the Gateway to Reset Heartbeat Counters (see
page 13). This will clear any LED fault lights on the Gateway as well.
NOTE: The remote and Gateway must be a minimum of 2 feet apart at all
times. If the units are placed closer than 2 feet apart, either unit may
experience temporary loss of RF functionality. If this occurs, simply
remove power for at least 30 seconds. Subsequent to powering back up,
verify functionality
NOTE: Fifteen remotes can be added to the network.
NOTE: In the event a remote has been deleted from the network,
subsequently adding a new remote will fill in the next available remote
location. For instance, if remote #3 was removed from a network of eight
remotes, then a new remote will be added as remote #3.
1. Verify the Network Address has been programmed on the Gateway (see page 10).
2. Prepare the Gateway for the Learn Operation (see page 11).
