The Buckeye Detection Systems (wireless monitoring) Network consists of 1-to-32 battery-powered wireless transmitters (BF-CAST), and at least one 32-channel wireless receiver (BF-LINK). Our wireless receivers take advantage of our NRTL-certified and field-proven BFC-4 controller hardware–along with a newly-designed firmware. A single Multi-Interface option module is the only unit required to add data logging, a second wired and wireless Modbus® port, and a Wi-Fi port with a web server. The unique Wi-Fi feature allows remote HMI functionality via a web enabled device. Buckeye wireless receivers allow responders to view real-time data and historical trends on smart devices prior to entering a hazardous area.
The battery-powered wireless transmitter is based upon our proven BFT-48 wireless transmitter and is compatible with existing BFT-48 systems. BDS-NET enhancements include power on/off via the magnetic wand, dual gas sensor capability, easy battery replacement, and the ability to separate the sensor up to 15-feet from the transmitter using a four-wire sensor separation kit. The BDS-NET wireless monitoring system is designed for rapid and easy deployment for both temporary and permanent monitoring applications.
Supports single/dual and local or remote “Smart” temperature compensated sensor
modules.
• Alarms, gas range and other parameters are stored in the Smart Sensor module and may be
edited by the user. Changes are periodically broadcast to the BDSNET wireless receivers to
ensure identical readings at all locations.
• Allows restore of factory settings from the Smart Sensor plus back up and subsequent restore
of user settings if parameters are accidentally corrupted or lost.
• Password protected with Low and High security levels.
• Easy to change Lithium battery.
• Three adjustable independent alarm levels per sensor.

• 5 front panel LED’s indicate alarms and communication status.
• Suitable for Division 2 hazardous locations.
• Available either in rugged cast aluminum or economical and durable UL-94 injection molded
Displays monitored readings and alarms from 1 to 32 BDSNET monitors.
• Limited setup required as channel parameters are periodically received from the BDSNET
sensors via the wireless network.
• Includes 8 programmable 5 amp relays to control lights, horns, fans, etc.
• “Acknowledge” feature allows audible devices to be silenced during alarms.
• Graphic LCD displays Engineering Units and bar graph for each active channel.
• Event log captures time and date stamps for multiple sensor events including: powerup,
alarms , calibration and communications errors.
• Ideal for use with solar power requirements (100 – 240VAC or 10 – 30VDC).
• Both 900 MHz and 2.4 GHz FHSS wireless options available.
• Touch and magnetic keypads are standard for non-intrusive calibration.
• Password protected with Low and High security levels.
The Multi-Interface module is a plug-in PCB option for the receiver which adds a tremendous amount of functionality and features and can be easily added to the BF-LINK receivers. The below features are provided with this option:
• Wi-Fi access point for web enabled devices to view BDSNET Receiver embedded
web pages including real time and historical sensor readings, channel parameters and remote
set up capability.
• Data logging storage of more than 1 year of readings and alarm history.
• RS-485 and wireless Modbus® slave port for transmitting data to BFC-16
and BFC-64 channel controllers.

The BDSNET wireless network is designed with maximum performance and east of setup.
The wireless equipment is easy to deploy since all BDS wireless equipment utilizes both 900MHz and 2.4GHz frequency ranges. Advantages are provided by the powerful BDSNET transmitters, as the wireless equipment can maintain solid connections to all components of the wireless network, despite obstructions that are common to typical installations. Once the wireless signal is received at the Wireless Controller (Server) there are multiple connection options available such as Wi-Fi, Wireless Modbus, and USB data logging.
2.4GHz frequency range: 2400 – 2483.5 MHz with 42 hops.
• 2.4GHz conducted transmit power is 125mW / 21dBm.
• 2.4GHz indoor/urban range: Up to 1500 feet with 7dBi collinear antenna.
• 2.4GHz outdoor RF LOS range: Up to two miles with high-gain antenna.
• 2.4GHz receiver sensitivity: -98dBm.
• 900MHz frequency range: 902 – 928 MHz with 50 hops.
• 900MHz conducted transmit power (selectable): 10mW-1W/0-30dBm.
• 900MHz indoor/urban range: Up to 3000 feet with 2dBi dipole antenna.
• 900MHz outdoor RF LOS range: Up to five miles with high-gain antenna.
• 900MHz receiver sensitivity : -100dBm enclosures.
A typical BDSNET FHSS Client / Server wireless monitoring system consists of one BDSNET
Receiver configured as the network’s Server, receiving wireless data from up to 32 Single Gas or 16 Dual gas BDSNET wireless transmitters. Additional BDSNET Receivers may also receive the same BDSNET transmitter’s data and act as remote alarm stations and displays, but must be configured as a Client since only one Server is permitted per network. BDSNET wireless transmitters are powered by an internal lithium battery while BDSNET receivers require either 100 – 240VAC or 10 – 30VDC and are very suitable for solar power.
