READ BEFORE OPERATING
All individuals who have or will have the responsibility of using, maintaining, or
servicing this product must carefully read this manual. The product will perform as
designed only if it is used, maintained, and serviced in accordance with the
manufacturer’s instructions.
The B5C is a state-of-the-art transmitter that can operate as an independent, stand-alone
system or as part of an integrated system. Setup procedures are simplified with user
friendly push buttons and LCD menus.
The B5C is the Q5C gas transmitter with BACnet® MS/TP master protocol. Therefore,
the B5C does not support the 4-20mA and VDC analog output.
BACnet MS/TP protocol is a peer-to-peer, multiple master protocol based on token
passing. Only master nodes are allowed to send and receive tokens on the MSTP
network. Passive slave nodes on the other hand may only transmit data frames on the
network in response to a request from a master node. Passing the token represents
overhead in the sense that the messages used for managing the token do not carry data
that is useful to automation or monitoring.
The B5C can be set to be a Master Node or a Slave Node in the field. Factory default is
master node.

2. Installation
2.1 Enclosures Physical Dimensions
The enclosure is a NEMA 4 rated enclosure and can be wall mounted with 4 screws. To
maintain the NEMA rating, it is important that the conduit opening is sealed upon
installation.
2.2 Location
The transmitter should be mounted where the gas to be measured is most likely to be
present. This location will be dependent on the source of the target gas and whether that
gas is lighter or heavier than air. Air circulation and mixture should also be taken into
account.
CO gas is lighter than regular air, it can be mounted on the walls at least a couple of feet
below the height of the ceiling. As the transmitter has a digital read-out, placing it at
about eye level is strong recommended.
The location should be accessible for the purposes of routine re-calibration and periodic
sensor replacement. Sufficient room should be left to allow the enclosure cover to be
removed and the connection of the calibration adapter to the sensor chamber. For sensor
element replacement there will need to be enough room to remove enclosure cover and
the sensor board assembly.
NOTE: The transmitter can also be installed in limited outdoor environment - An
ambient air environment that is not climate controlled and is not in direct contact
with the elements of nature, such as wind, rain, sleet or snow. Examples of limited
outdoor environments include parking garages, construction complexes, sports
venues, boats and recreational vehicles.
NOTE: Avoid mounting the transmitter near 600 VAC switchgear and other
sources of radio frequency and/or electromagnetic interference. While RFI/EMI

protection is built in to the transmitter, excessive levels of interference may cause
instability in the output signal.
2.3 Terminals
B5C Terminals
2.3.1 Wire and Cable
Terminal blocks TB1 to TB7 accept 12 AWG to 24 AWG wire. Use 16 AWG or 18
AWG wire for the power supply in long wiring runs, which can be up to 1km (1,000
meters) long.
We recommend using BELDEN 9841 for communications. This wire has 120 ohm input
impendence, which will eliminate RS-485 communication problems.

2.3.2 RS-485 Terminator
The terminator on each end of the RS485 run is designed to match the electrical
impedance characteristic of the twisted pair wire, and will prevent signal echoes from
corrupting the data on the line. The terminator should be enabled on BOTH ends of the
RS485 run. Short and medium length Modbus/485 runs can operate without the
terminating resistor. Longer runs may require the terminating resistors. But adding
terminator dramatically increases power consumption.
Factory default setting is disabled terminator.
The B5C supplies this resistor on the main board, and it is chosen using a jumper at J4.
J4 1-2: Terminator Disabled / OFF (default)
J4 2-3: Terminator Enabled / ON
2.3.3 RS-485 Driver Replacement
RS-485 lines in heavy industrial environments are sometimes subjected to magnetic
disturbances causing sufficient inducted power surges to damage the driver integrated
circuit (IC). This IC (U6) has a socket on the circuit card for ease of replacement in the
field.
2.3.4 Relays Output
The B5C has three onboard programmable Single-Pole Double-Throw (SPDT) relays.
These relays can be used to control other equipment, such as fans, lights, horns, etc.
eliminating the need for a separate controller.
Three terminal blocks (TB1, TB2 and TB3) are located on the main board. Each relay can
be programmed individually.
Switching capability of each relay is:
1.0 A maximum resistive load at 30 VDC
0.3A maximum resistive load at 125VAC

2.3.5 Note for B5C:
The B5C supports BACnet MS/TP protocol and can be networked to form a BACnet
MS/TP network.
The B5C default baud rate is 38400bps.
Each B5C on the MS/TP network must have a unique BACnet MAC address and unique
Device Instance Number (Object ID).
B5C valid MAC addresses are 0-127 for master node, 0-254 for slave node.
B5C default MAC address is 126.
Default Device Instance Number (Object ID) is 4005.
The B5C power supply and RS-485 connection are similar to the Q5C. The B5C doesn't
have terminal blocks TB4 and TB6.
Avoid running communication wires or sensor input wires next to AC power wires or the
relay output wires. These can be sources of noise that can affect signal quality.
The B5C has a half wave rectifier on board. You will damage devices if you mix half
wave and full wave rectifiers on the same AC source. Use extreme caution when
sharing a common AC source. Sharing a common DC source is less problematic.
When the B5C input power is AC, the 24VAC can be either grounded or non-grounded.
Polarization is very important when the B5C is connected to a network. Make sure the
Neutral is connected to the GND of TB5.

3. Function and Configuration
3.1 Indicators
The indicators consist of five LED’s – two to indicate RS-485 digital communication,
three to indicate the status of relays 1-3.
3.1.1 RS485-TX/RX:
When the B5C is connected to a controller system via RS-485, the traffic of the
communication can be monitored visually through the two RS-485 indicators. One is RX
LED, which indicates the data stream received in from the controller. The other is TX
LED, which indicates the data stream out of the B5C.
Note: If the TX LED or the RX LED is always ON, is indicative of a communication
problem. See Troubleshooting for RS-485.
3.1.2 Relay 1-3 LED:
Indicate the status of each relay. When the relay is actuated/closed, the relay LED is ON.
When the relay is de-actuated/open, the relay LED is OFF.
Note: If you set the relay to be Normally Energized (Fail Safe), the relay LED will
turn ON at non-alarm state and turn OFF at alarm state, because the LED reflects
the relay coil status.
