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 Re- Transmitted at 900 MHz to a 900 MHz Receiver up to 1,000 feet away. The 900 MHz receiver picks up the information from the re- peater and then passes it along to the 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. Duct Temperature Transmitter Mounting 418 MHz Up to 100 Feet Transmitter Transmits the Temperature Information 900 MHz Receiver Receives the Temperature Information from the Repeater and passes it on to the Analog Output Modules Analog Output Modules Converts the Temperature Information into an analog resistance, voltage or current for the BAS controller Fig. 2: 900 MHz Wireless System 900 MHz Up to 1,000 Feet Repeater Receives the 418 MHz Temperature Info from the Transmitter and Re-Transmits it at 900 MHz up to 1,000 feet Fig 3: Wireless Duct Temperature Sensor Mounting and Hole Pattern, Rotate 90° for Horizontal 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 stratified air, coils or humidifiers 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. 418 MHz Up to 100 Feet Transmitter Transmits the Temperature, Humidity, Setpoint and Override Info 418 MHz Receiver Receives the Temperature, Humidity, Setpoint and Override Info from the Transmitter and passes it on to the Analog Output Modules Analog Output Modules Converts the Temperature, Humidity, Setpoint and Override Info into an analog resistance, voltage, current or relay for the BAS controller Fig. 2: 418 MHz Wireless System19705_ins_wireless_duct_temp_xmitr Installation and Operating Instructions Wireless Duct Temperature Transmitter 418MHz Building Automation Products, Inc., 750 North Royal Avenue, Gays Mills, WI 54631 USA Tel:+1-608-735-4800 • Fax+1-608-735-4804 • E-mail:sales@bapihvac.com • Web:www.bapihvac.com rev. 04/21/15 2 of 5 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 defined sequence on the transmitter and output module. The train- ing process is easiest on a test bench so the units are within arm’s reach of each other. Training can be done in the field but requires two people and a set of walkie talkies or cell phones. Place an identification 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 flash about once every 20 seconds, indicating a transmission. (The flash 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 flash 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.)

Battery Connectors Transmitter Module 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 film 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’s should be mounted as far away from metal plates or bars as possible to avoid RF energy being reflected 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, floors, 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.

The text and figures 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 fit 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 fit 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 first 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 configuration 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 fit onto one piece of DIN Rail, then mount another piece nearby and attach your additional modules. Connect wires from the right side of the first 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 configuration 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 fit in one straight line on the surface, then mount a second string of modules nearby. Connect wires from the right side of the first string of modules to the left side of the second string of modules. (See “Extending the RS485 Network...” on pg. 5.) This configuration requires one or more Pluggable Terminal Block Connector Kits (BA/AOM-CONN). Fig. 7: Receiver & output modules mounted on DIN Rail.

The wireless receiver and Analog Output Modules are interconnected and require module power along the “Power Bus” terminals. The bus can be powered from either the receiver end on the left or the last output module on the right side. Be sure you have enough DC current or AC VA for all the devices on the bus. 2. The Current Output Module (BA/COM) signal is LOOP POWERED and must be externally powered with 9 to 36 VDC separate from the Power Bus. The Loop Power must be connected to the Current Output Module before it can be trained. 3. Be sure to follow the polarity (+ or –) symbols listed on each receiver and the output modules to maintain communication and Power Bus integrity.

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. - Retrain the Analog Output Module. - Check for proper wiring and connections from the output modules to the controller. - Check to see if the controller’s software is configured properly. - Check to see if the correct output module is connected to the correct controller. 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 indefinitely. • 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. Possible Problems: Temperature or Humidity is reading its low limit or high limit, or the LED at the top of the Analog Output Mod- ule is blinking rapidly: Temperature or Humidity reading is coming out the wrong output module Temperature or Humidity reading is incorrect Extending the RS485 Network between the Receiver and the Analog Output Modules The Analog Output Modules may be mounted up to 4,000 feet away from the receiver. The total length of all the shielded, twisted pair (TSP) cables shown in Fig 12 is 4,000 feet (1,220 meters). Connect the terminals together as shown in Fig 12. If the dis- tance from the receiver to the group of Analog Output Modules is greater than 100 feet (30 meters), provide a separate power supply for that group of Output Modules. BAPI’s VC350A-EZ Voltage Conv. and a small transformer are a perfect solution.
