Wireless System Overview
418 MHz System:
The transmitter measures the Duct Temperature and
sends the data at 418MHz to the 418 MHz Receiver up
to 100 feet away. The transmit rate is about once every
20 seconds with an estimated battery life of 5 to 8 years
with two high-capacity 3.6V lithium batteries.
The transmitted info is picked up by the 418 MHz
Receiver and passed along to an Analog Output Module
which converts it into an analog resistance, voltage or
current which is then hard wired to the analog inputs of
the BAS controller.
900 MHz System:
The transmitter measures the Duct Temperature and
sends the data at 418MHz to a Repeater up to 100 feet
away. The transmit rate is approximately once every 20
seconds with an estimated battery life of 5 to 8 years
using two high-capacity
3.6V lithium batteries.
The 418 MHz transmitted
info is picked up by the
Repeater and then ReTransmitted at 900 MHz to
a 900 MHz Receiver up to
1,000 feet away. The 900
MHz receiver picks up the
information from the repeater and then passes it

Duct Temperature Transmitter Mounting
First train the transmitter and output modules as
shown above on the next page.
1. Place the sensor in the middle of the duct
away from temperature stratied air, coils or
humidiers to achieve the best temperature
reading.
2. Drill the probe hole as in the hole pattern graphic
shown below. Insert the probe into the duct.
3. Mount the enclosure to the duct using BAPI
recommended #8 screws through a minimum
of two opposing mounting tabs provided. A 1/8
inch pilot screw hole in the duct makes mounting
easier through the mounting tabs. Use the
enclosure tabs to mark the pilot hole locations.
4. Snug up the sensors so that the foam backing
is depressed to prevent air leakage but do not
over-tighten or strip the screw threads.

Installation and Operating Instructions

Analog Output Module Training
The installation process requires that each transmitter is trained to its associated output modules so that they receive communications
from the correct transmitter. This is done by pushing buttons in a dened sequence on the transmitter and output module. The training process is easiest on a test bench so the units
are within arm’s reach of each other. Training can be
done in the eld but requires two people and a set of
walkie talkies or cell phones. Place an identication
mark on the transmitter and associated output module
after training so they can be matched at the job site.
Any transmitted variable can be trained to more than
one output module. If a Repeater is used, be sure it is
powered and within reception range of the transmitter
and the 900 MHz Receiver to train the output modules.
TRAINING PROCEDURE
1. To train an output module to the temperature
transmitter, select the Resistance, Voltage or
Current Output Module you want to train and
connect it to the wireless receiver. Note: Multiple
output modules can be trained to the same transmitter variable if desired.
2. Apply power to the receiver which will supply power to the connected output
modules. The power LED on the receiver will light and remain lit. (Current Output Modules
must have loop power supplied to the module itself before they can be trained.)
3. Open the BAPI-Box cover on the transmitter and remove the battery tabs or install the batteries,
observing polarity as shown in Fig 4. The small LED on the transmitter module will ash about
once every 20 seconds, indicating a transmission. (The ash is very quick.)
4. Press and hold down the “Service Button” on the top of the output module (Fig 5) that you wish
to train. Then, press and release the “training button” (see Fig 4) on the transmitter module.
When the output module receives the “training transmission” from the transmitter, the output
module’s red LED will light. Release the “Service Button” on the output module and the red
LED will go out. The transmitter and output module are now trained to each other. During
normal operation, the output module’s LED will ash about once every 20 seconds indicating data reception.
5. Mount the transmitter at the desired location (as shown on the previous page), removing the batteries if needed. (The units will
remain trained to one another through power failures and battery replacement.)

Mounting and Locating of the Antennas on the 418 MHz Receiver, 900 MHz Receiver and the Repeater
The 418 MHz Receiver, 900 MHz Receiver and Repeater may be located inside a metal enclosure but their antennas must be outside
the enclosure. The 418 MHz Receiver comes with a 418 MHz Dipole Antenna. The 900 MHz Receiver comes standard with a 900 MHz
“Whip” Antenna but is available with a 900 MHz Dipole Antenna. The Repeater comes standard with a 418 MHz Dipole Antenna and a
900 MHz “Whip” Antenna, but is available with a 900 MHz Dipole Antenna.
To mount the 418 MHz Dipole Antenna or 900 MHz Dipole Antenna, peal off the protective lm from the adhesive pad and stick the
antenna to a wall or other non-metallic support so that antenna is vertical for best reception. Antenna’
from metal plates or bars as possible to avoid RF energy being reected back or blocked on the other side of the metal. An antenna will
not work inside a metal box. Mounting to drywall between studs, ceiling tiles, brick, or concrete is very common.
Transmission distance performance will vary based on environment. 100 feet is the maximum that can be expected if there are no
obstructions. In general, each obstruction will half the expected transmission distance. Obstructions include but are not limited to;
walls, partitions, oors, ceilings, doors, tinted
glass, ground, many people, vehicles, foliage,
rain, snow and fog. Metal (solid or screen)
blocks the RF signal preventing propagation but
also can bounce the signal around the potential
obstacle. Wood, drywall, plaster, brick, and
concrete attenuates the signal but will let it pass
(if it’s not too thick) at a reduced signal strength.
Anything that holds water absorbs the signal
to the point of blockage like rain, fog, people,
ground, dense foliage etc. Elevator shafts and
stairwells usually block RF signals.
The 900 MHz “Whip” Antenna simply screws
onto the 900 MHz Receiver or the Repeater.
Mounting the antenna on a metal surface may
limit reception from behind the surface.
Note: The Dipole antennas above are displayed horizontally to show dimensions but

Mounting of the 418 MHz Receiver, 900 MHz Receiver and Analog Output Modules
rev. 04/21/15
The 418 MHz Receiver, 900 MHz Receiver and Analog Output Modules can be
mounted in snap track, DIN Rail or surface mounted. The text and gures refer to
the 418 MHz Receiver, but the mounting process is the same for both receivers.
SNAPTRACK MOUNTING
Push in the blue mounting tabs on the bottom of the receiver and output modules.
These units will now t into the board slots of 2.75” snap track. Insert the receiver
at the far left of the snap track, then insert each analog output module and slide it
to the left until its connectors are fully mated into the receiver or the next analog
output module. You may attach up to 127 analog output modules to a receiver.
If your output modules cannot t in one piece of snap track, then mount another
piece of snap track nearby and insert the additional modules. Connect wires from
the right side of the rst string of modules to the left side of the second string of
modules on the second snap track. (See “Extending the RS485
Network” on pg. 5.) This conguration requires one or more
Pluggable Terminal Block Connector Kits (BA/AOM-CONN).
DIN RAIL MOUNTING
Push out the blue mounting tabs on the bottom of the
receiver and output modules. These units will now snap
onto DIN Rail. Catch the EZ mount hook on the edge of the
DIN rail as shown in Fig 8. Then rotate into place.
Attach the receiver at the far left of the DIN Rail, then attach
each analog output module and slide it to the left until its
connectors are fully mated into the receiver or the next
analog output module. You may attach up to 127 analog
output modules to a receiver.
If your output modules cannot t onto one piece of DIN Rail,
then mount another piece nearby and attach your additional modules. Connect wires from the
right side of the rst string of modules to the left side of the second string of modules on the
second DIN Rail. (See “Extending the RS485 Network...” on pg. 5.) This conguration requires
one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN).

SURFACE MOUNTING
Push out the blue mounting tabs on the bottom of the receiver and output modules. Attach the
receiver to the surface by inserting a screw in each blue tab. Attach Analog Output Modules by
placing each one against the surface and sliding it to the left until its connectors are fully mated
into the receiver or the next analog output module. Attach each module to the surface with two
screws, one in each blue tab. You may attach up to 127 analog output modules to a receiver.
If your output modules cannot t in one straight line on the surface, then mount a second string
of modules nearby. Connect wires from the right side of the rst string of modules to the left
side of the second string of modules. (See “Extending the RS485 Network...” on pg. 5.) This
conguration requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN).

Possible Solutions:
- Check for proper wiring and connections from the output modules to the controller.
- Check to see if the controller’s software is congured properly.
- Check for proper power to the receiver, repeater (if used) and output modules.
- Retrain the Analog Output Module.
- Check that the associated transmitter is transmitting (the LED will ash about once
every 20 seconds when it transmits). If not, replace the batteries. Check that the
associated receiver is receiving the tranmissions (its LED will blink right after the
transmitter LED if it receives that transmission.) If it is not receiving the transmissions,
move it closer to the transmitter or reposition the antenna for maximum reception.
Note: The receiver will receive transmissions from all transmitters that are within
range, not just the one you are testing.

Analog Output Module Default Status when Wireless Transmission is Interrupted:
If an output module does not receive data from its assigned transmitter for 15 minutes, the red LED on the top of the module will
blink rapidly. If this happens, the individual Analog Output Modules will react as follows:
• Resistance Output Modules (BA/ROM) calibrated for temperature will output the highest resistance in their output range.
• Voltage Output Modules (BA/VOM) calibrated for temperature will set their output to 0 volts.
• Current Output Modules (BA/COM) calibrated for temperature will set their output to 4 mA.
• Voltage Output Modules (BA/VOM) calibrated for humidity will set their output to their highest voltage (5 or 10 volts).
• Current Output Modules (BA/COM) calibrated for humidity will set their output to 20 mA.
• Setpoint Output Modules (BA/SOM) will hold their last value indenitely.
• Relay Output Modules (BA/RYOM Units Only) will go to their default state (example: open for a normally open unit).
When a transmission is received, the output modules will revert to normal operation in 60 seconds or less.
