Networked Gas Detection SensorCar Dealership Service Area: Honeywell Analytics E3Point system installed to protect service technicians from Carbon Monoxide exposure. The E3Point system has become the industry standard for CO detection in commercial space. 

E3Point Honeywell AnalyticsE3Point Networked Carbon Monoxide (CO) Sensor located in service technician’s work area. Networked sensors are easy to install and only require 4 wires. Versions of the E3Point sensor include: Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Oxygen (O2), Hydrogen (H2), Hydrogen Sulfide (H2S), Methane (CH4) and Propane (C3H8).


Gas detection calibrationCalibrating an E3Point Carbon Monoxide sensor is required to ensure proper accuracy and functionality of the sensor. Calibration is quick and easy, and each sensor can be commissioned in less than 5 minutes.


301C Controller Honeywell AnalyticsThe Honeywell Analytics 301C Controller communicates with a network of E3Point Carbon Monoxide (CO) sensors. The 301C is capable of monitoring a network of up to 96 sensors. Versions of the 301C controller are also available with data-logging and Bacnet IP communication abilities.


Honeywell Analytics Gas Detection ControllerWiring the 301C controller is clean and simple. The 301C is freely programmable and features 4 onboard relays and 1 Horn Buzzer for sequencing of ventilation systems and alarms.


Honeywell Analytics E3Point CO SensorStand Alone version of the E3Point Carbon Monoxide (CO) sensor. This sensor is located within a Service Drive Thru area small enough to require only one sensor in the space. The Stand Alone CO sensor has 2 onboard relays and a Horn Buzzer. In this application the sensor is wired to energize an exhaust fan, open the garage doors and sound an alarm horn in response to increasing levels of CO in the space.

Part 2: Start Up of A Carbon Monoxide (CO) Gas Detection System

This blog is Part 2 of our three part case study on Implementing a Carbon Monoxide (CO) Gas Detection System in a car dealership’s service area. Read Part 1:  Designing a Carbon Monoxide (CO) Gas Detection System

Once the install was complete, CCI was onsite for system start up and commissioning. This project was divided up into 3 areas of the building.

Honeywell Analytics E3Point CO SensorArea #1: Service drive-thru reception area
The first area we programmed was a small service drive-thru reception area. This space was small enough to require only one standalone CO sensor. We programmed the sensor’s onboard relays to energize an exhaust fan and open garage doors when CO concentrations reached a low level set point. We then programmed a horn alarm to sound at a high level set point.

Networked Gas Detection SensorArea #2 & #3: Service garage
The second and third spaces were two large areas in the service garage. For this application we used a series of eight CO sensors spread throughout the two spaces. The sensors were all networked back to a central control panel near the service manager’s office. For this application we implemented a zoning strategy for the 2 spaces, Zone #1 consisted of five CO sensors, Zone #2 consisted of three CO sensors. The controller was programmed so that if any one sensor in a zone reached a low level CO set point, a relay onboard the 301C controller would energize and call on the zone’s exhaust fan and make up air unit. We also programmed the controller to sound an alarm once a high level CO set point was reached.

We then used a cylinder of CO test gas to test the accuracy of the CO sensors and re-calibrated the sensors as needed. Functionality of the mechanical equipment was also tested as part of the system start up. Once the commissioning was complete we returned to the office and drafted a Factory Authorized commissioning report for the building owner.

This project was a classic example of Carbon Monoxide detection in a commercial space. The Honeywell Analytics E3Point products provide a top of the line, reliable system that can be trusted to deliver results. Just as important, for the experienced contractor this system is quick and simple to install and commission.

Solutions for Expanding the Number of I/O Points in the Field

ACnet MS/TP and Modbus RTU input and output modulesContemporary Controls now offers BACnet MS/TP and Modbus RTU input and output modules to provide a convenient way for expanding the number of I/O points in the field. These modules, called “Cube I/O”, are compact, cost-effective modules available with analog and digital inputs and outputs in varying combinations.

In a MS/TP application, if the controller is short a few I/O points, the Cube I/O is an easy addition. Wire the module to the MS/TP communication cable, use the existing 24 VAC power (assuming your other devices are half-wave rectified) and discover the points as standard objects via a BACnet client. You are now ready to build on your application.

Need some retentive inputs for counting utility pulses (gas, water, air, electricity) but your controller is not retentive, or cannot support an accumulator function, or has no free input points – no problem. Use the BMT-SI4 (4 independent points) accumulating pulses at a rate of 16 pulses per second. Expand the scope of the project with minimal additional expense.

The analog MS/TP and Modbus RTU input modules both support 10K type 3 thermistors, 0 to 10 VDC, and in addition Balco 500 RTD and PT and NI sensors. Cube analog input module provides support for a comprehensive variety of sensors for those applications requiring standard and specialty sensors.

Planning on using the BASgatewayLX to convert some Modbus data to BACnet/IP instances? If you need to pick up some additional points, either input or outputs the Cube I/O can be added to the BASgatewayLX and the head end BACnet/IP controller can read and write the added Cube I/O in addition to obtaining the data from the Modbus device(s). Need to add some retentive pulse accumulators? Use the Modbus RTU MR-SI4 to get the job done.

Use the Cube I/O with the BASremote. Need to add some I/O but don’t need the flexibility of the universal inputs and outputs of the BASremote expansion module. Plan to use the appropriate Cube module(s) connected to the Modbus port of the BASremote. You can even power up the Cube I/O from the BASremote Auxiliary Power Output terminals. Clean and simple.

The BACnet MS/TP and Modbus RTU Cube I/O modules offer the following module combinations:

  • 4 or 10 point input module
  • 4 point retentive pulse input module
  • 8 point analog input module
  • 4 point relay output module
  • 4 point analog output module
  • 4 point input and 2 relay output module

Modules have the following operational specifications:

  • operates at 20 to 28 V AC /DC
  • selectable baud rate of 9,600 to 115,200 for both MS/TP and Modbus RTU
  • 2 wire RS485 communications
  • operating temperature of -5 to 55 Degree C
  • DIN rail mounted
  • LED’s for bus activity, error indication and I/O status
  • polarity reversal protection
  • small size

The modules are designed to minimize wiring. If multiple Cube I/O modules are used in an installation each module can be jumped to the module next to it, and then the next module jumped to the next and so on. This provides a quick and clean installation. All power and communications are jumped between the modules. In fact the Cube line offers a 24 VDC power supply that can be the head end of a chain of jumped Cube I/O.

Carbon Monoxide (CO) Gas Detection System Case Study: Part 1

Carbon Monoxide Detection

E3Point Standalone Controller

Control Consultants, Inc. was tasked with designing and implementing a Carbon Monoxide (CO) gas detection system for a car dealership’s automotive service area.

We began the project in the design phase. Our engineering team reviewed mechanical plans and construction documents to determine the proper system sizing and control strategy. A Honeywell Analytics system was chosen based upon engineer’s specifications, and our design resulted in a system consisting of the following:

Our engineers drafted point-to-point wiring diagrams using AutoCAD and provided a full submittal package to the project’s MEP engineer. Once the submittals were approved, materials were provided to the mechanical contractor for installation.

After the install was complete, CCI was onsite for system start up and commissioning

The Largest Valves In The World

Ball Valve

Source: Nord Stream AG

The Nord Stream natural gas pipeline in the Baltic Sea is the largest sub-sea pipe line in the world. It is 760 miles (1224 km) long and goes between Vyborg Russia and Greifswald Germany. Some of the pipes are over 3 ½ feet in diameter and over 1 1/2 inch thick. As you can imagine the valves in this pipeline are <b>huge</b>! 10 custom designed valves were manufactured for this project by Petrovalves Srl in Italy. At 102 tons each and over 30 feet high, the double-gate valves for the project are the heaviest valves in the world. The valves protect the entrance and exit of the pipeline and are capable of pumping 55 billion cubic meters annually. The Nord Stream pipeline has been supplying natural gas to Europe since November 2011.

Check out this video of the largest valves in the world to see how Nord Stream transported the 102 ton valves from Italy to the German Baltic Sea to be installed for the pipeline.

While CCI doesn’t sell the largest valves in the world we do sell valves online. CCI also assembles Honeywell Ball Valves and Valve Actuators here in our warehouse so that we can offer a large assortment valves with a short lead time.
